This didn't just happen over night, it was a long process to get to where we are and took many great minds. It would be cool to see a documentary more into the history and evolution of this stuff. It's cool to see old physical records people used to listen to music on and the old cameras they used to take pictures physically vs digitally.

We have these big brains and eyes gotta use them for something.

That can't be right. I learned this along with much more detail some 40 years ago. They were called books, we carried them and had to read/study them. The professor played the role of the video with blackboard showing the concepts. And we were required to write a low level program to read/write data on disks as part of the class. Don't get me wrong, I love that there's videos and that regular users can see inside the components of a computer system.

Agreed. Meanwhile, too many people pay to watch lame sports/shows. Just a few hours ago, I proceeded with signing up for TH-cam Premium....because of Branch Education. And I hope that some of my payments go to Branch Education for their efforts.
I have 10+ years of experience working with SSD firmwares, but hadn't understood SSD internals so better in such a short time. Thank you for this informative video !!!
what always gets me with all these highly intricate parts are not only the high levels of complexity that is built into them, but also the fact that someone devised a way to etch out literally nm of material in such a specific and highly accurate manner and that there's little to no mistakes on every sold product.
This is SO incredible. I consider myself a tech enthusiast, and knew that it was very complex, but it's truly shocking how intelligent people are; the designers of SSDs, and their predecessors, are unbelievably brilliant.
It really puts into perspective how far behind the rest of humanity is we all thrive off of a technolgy that only a hand full of humans can even build from scratch. Like monkeys that enjoy macaroni and cheese but have no idea how to make it them selves.
That is also exactly how televisions work, or some "holographic" cubes work. And it is based on how every computer has been working these last 40 years or so
@@thepiyushsharrma I will. I think I'll explore communication satellites and the engineering of how a satellite phone on earth can communicate with something in space. First I gotta finish a few episodes more on SSDs/ VNAND
I bought a 4TB external SSD that fits in my hand so I was curious how it's possible and how it works.. It's insane how the tech world has made it possible to store so much data it such a small place..
Same here. Yes, it's like magic what these smart people create! Kudos. I hold it in my hand, and knowing that 2 complete Movie Projects are stored there. Despite the bad times, what a wonderful time to be alive.
I totally forgot this was a free video that the creator made just to educate whoever comes across it. Very good production value and the information is given at a level which is both accessible to those with little to no understanding of technology while still being informative to those who are technical but have no experience with this particular technology. Massive kudos!
Thanks!! I appreciate it. It is indeed growing incredibly fast. It’s just insane how quickly companies can turn around new designs of SoCs and other microchips.
@@DP-ot6zf yea thats very true its the apiece of success when you think its normal to have such a device in your pocket to the point where you cant live without it! TRUE!
Well memes can help bring the stress down from your system through laughter and joy, which in turn will make you able to be more productive, of course when not abused. And complaining about your life is the first step before actually doing something about it, and we all need a first step. So there you go, Divine Wisdom still there, untouched, within you, within your device.
I like how you demonstrate the basics of electronics "building blocks" and "duplication". Many circuits follow this standard recipe; create a circuit and duplicate it. Good job getting all of the information across in a fun visual. Funny how far we have come from the simple D-latch memory.
seems more like the companies care about having "the best" camera but in reality, people just want a decent camera - which most higher end phone has these days. I mean.. can you tell which picture is taken with which phone? Imagine having a 200 pic collage taken with the top 200 mobile phones, and you just had to guess which phone took which picture. You can't. this whole "camera race" is lame My old S7 edge took great pictures and i cant really tell based on my albums when i switched phones (i got the S9 these days - replaced S7 due to screen having "pink lines" for some reason)
An additional thing to this video is I read an article about SSD drives that said the controller also keep track of how many times a cell has been used because the number of times a cell can be used is limited compared to traditional hard drives. The controller actually locates the least used cells in memory and that's where it saves information, in other words a file could be all over the place bit by bit instead of stored sequentially.
The controller in a HDD does similar things. Your data in the HDD isn't stored sequentially in most cases as well. But sequentially writes (and reads) are faster and therefore preferred when possible.
@@JustSomeGuy009 Yes, correct, so back in the days we used these programs that would rearrange the files they are stored sequentially because with a mechanical read/write head it improved the speed of reading files and also prolonged the life of the drive.
@@JustSomeGuy009 It's really not the same thing at all. For solid state memory, getting blocks in order that way is not especially important, but what is important is not writing to the same cell too many cells over the course of its life. Wear leveling is the usual name, and it's important.
There's a surprising amount of art related skills. Designing PCBs are pretty much a massive multi layer connect the dots, I've done it, and made little pictographs in the corner of my PCBs for fun.
One of very rare videos, that are not afraid of being technical. I loved it, especially comments through subtitles, adds some replaybility and also had me know more about the content. I hope I can learn more here. Being a CS student who like computer systems, and hence love to interact with lower layers, I find this very insightful
I'm an engineering student Finally you're the only person who given me the answer of this mystery . You have worked hard for spreading your knowledge. I'll tell my friends to subscribe your channel
There's no "perfect" way of speaking. Pronunciation varies and language evolves over time due to this. This is the first thing you learn in linguistics. There is no "right" or "wrong" way to pronounce words, within reason. Spelling, on the other hand, has no variability.
I graduated from engineering university but I did never fully understand how these memory cells work . Watching your video for 18 min enlightenmented my whole life
Understanding how this kind of stuff works while watching it on my phone made me lock the screen and literally just stare at it and imagine how incredible it is that there is this much technology in such a tiny device
I usually don't write comments. But man, your explaining is so concise and clear, that I can follow along seamlessly. The solid state drive technology is absolutely mind-blowing and so incredibly fast.
i am a tech enthusiast and just started a channel about technology and gadgets so i wanted to learn more about gadgets technology to help more people and gain knowledge and found your video now i feel like i know only 10% .... so much to learn about. ty
Technology is a very broad concept. The technologies existed. CMOS was invented in the 1960s. Nand Flash memory is a direct development of EPROM. And so on. Basic manufacturing principles also remains pretty much the same. (One example of this continuity: Large parts of the industry switched from metal gates to self aligned gates made out of polycrystalline silicon in the late 1960s, but went back again to metals (cu or al) around year 2000, for better performance in CPUs.) But, sure, the "constant" shrinking (until now!) of transistors has made manufacturing and processing techniques much more elaborate and expensive since 1978.
You guys didn't experienced on your time but take note all improvements currently are just and ideas in your time, and still they are using bit. in short they can't skip inventing from 1970's directly to 2020
You are not alone mate, I designed a product that first used 1K memory, it was soon replaced by a 4K static ram, then they stopped making those as technology moved on so fast, I had to change my pcb layout to accomodate bigger chip , then that became obsolete and had to use a 16K chip with 15K going to waste, only 1 K being used, so these have become obsolete now for quite some time, over a decade ago, but you can still buy some old stock, so now no one bothers with 128K, or 256K and all of these are now becoming defunct replaced with serial memories, of mega and giga bits!
@@mgabrielle2343 Hmm... Perhaps in the 1970s. But things have been pretty stable since the mid 1980s. You can still buy static RAMs as small as 8Kx8 (i.e. brand new, no old stock). The ubiquitous 32Kx8 SRAM (62c256 an similar) are still considered a standard component, with several different manufacturers over the world.
This is the first time I appreciate the multiple ads in a video, it helped my brain to catch up what's been said. Superb narration! Didn't realize 17min has passed so quickly. 👍
I absolutely loved the creators comments, given extra important information while adding insight of how much work went into this video. Gives a greater perspective on how much work good teaching methods actually take
This is an amazing visual explanation. I worked in flash-based data recovery for 2 years. I was familiar with the logical structures and relative sizes of pages, blocks and banks (the 8 stacks of chips inside the physical package), but I could never visualise them physically before watching this video. At least not the internal structure of the blocks. I have seen many X-rays of VNAND, and your depiction of the 8 staggered banks top of each other, with the rows of copper wire bonds between them was 100% accurate. I think I’d love to see your take on how flash controllers work, how they translate coherent binary from say an ascii text file, to the heavily obscured mess that actually gets written to the NAND. If your file is made up of the binary ‘1010 1010’, that is not the sequence that gets stored physically, Contiguous logical data like that ‘1010 1010’ sequence will first get split up and scrambled with a XOR pattern, than turns it in to effectively ‘random’ data. It then gets split across different pages, belonging to different blocks on different banks. This is called the “flash translation layer”, effectively the layer of logic that converts logical data storage to physical data storage. All this is done so that any given file is stored in as many separate pages as possible. You can only access one page per block at a time, so it would be slow to have to wait for every page to be read sequentially if your whole file is stored in one block. Instead, if you split a single file across many blocks and many banks, you can read multiple pages of that file simultaneously, speeding up the read and write processes. This method of parallelising data access is why solid state drives have become so fast. Instead of having one person read a 100-page book page-by-page, you split the book up in to 100 separate pages, and have 100 people read a page simultaneously. Once they’ve each read a page, it’s quicker to rearrange them in to the order of the pages they read, than it would have been to wait for one person to read all 100 pages.
Awesome video! I am a VLSI engineer who worked on LPDDR3/LPDDR4 and memory controllers myself, I can say this is really a great way to introduce a memory chip !😄
As an nand flash controller engineer, this is the most clearly video description about nand flash’s structure I’ve ever seen ... that’s an amazing job! Thanks for sharing.
wonderful video, the explanation is very clear, i am Vietnamess, your clear and slow voice not only help me understand a lot this information but also everyone on whole the world, thank you so much
I never said that on youtube in my entire life except when I discovered your channel but: I feel terribly thankful to be born at that time to have the chance to access such quality educational content for free and honestly realizing that at the end of your video made me sincerly feel emotional and I had tears from such wholesomeness. And believe me, getting emotional for something like this rarely happened in my life. Sincerely, Thank you for you time, work, dedication, ability to explain. These 17 minutes felt like 3.
Am a Mechanical engineering final year student, I wondered how it works since my 10th standard... It's a superb video, the graphic design explain the content in such that each and everyone could understand it very easily. Loved it. Thankyou
Thanks!! I don't search for conspiracy theories, or care much for them- but I bet there's one that says microchip technology was given to us by aliens.
@@Nikkk6969 I mean it's extremely difficult to reverse engineer modern SOCs. I don't see how anyone could reverse engineer a chip likely more complex than the ones we have today. The Field Effect Transistor was proposed in 1926 and there was a long history of research into electricity before that. en.wikipedia.org/wiki/Transistor And if a probe crashed on Earth that would mean a lot more should be finding us because of how large space is and how far apart planets are. There would need to be many populated planets out there sending out probes in many directions. It will take Voyager millenia before it finds a planet.
@@chaoticmasterpiece That old Moores law does not really hold anymore. Physical limits in scaling are reached for most kinds of chips. But NAND Flash (used in SSD) are built in multiple layers. So that's why they can continue to develop without even shrinking the transistors any more. Processors get far to hot for that method. Many other types of chips do as well.
It really blows my mind what our species has managed to achieve. All of these unfathomably complex technologies sitting in the palm of my hand as i type this. Really gives me a newfound appreciation for being born in this era of our history.
Wow, this really is amazing. The incredible small sizes of technology - if there weren‘t people like you describing it, it all would be like obscure magic.
it's still obscure magic. how can the charge trap be read? like how does it receive the signal to send the message of how many charges it holds? fascinating
Yea its one of the many things we use everyday that are JFM( Just F**king Magic) But yea how they are able to read each cell and how precise is that voltage per cell would be cool to know also what material or element are they made of? Its like most things in tech we have now in that its a voodoo black magic onion and there's always a more incredible thing as you go deeper into the next layer.
Defense world is essentially decades way ahead of the civilization is told! It's scary but awesomeness too. I also love the fact I will never decide to be on the wrong recieving end of the USA 🇺🇸!
Brother you are the king in our hearts. Amazing video that explains in graphic information that we all need to know and understand. I’m a fan of your work. Love it all
Everyone take a second and imagine how insanely large the .blend file for this video must be. Now imagine all the memory cells that contain the data. Imagine how crazily advanced it is that some electrons zooming through metal on a PCB are able to be processed by a CPU, GPU, and an SSD for storage. Then they get sent to a screen on your phone and give you an animation like this. My brain is thinking of all the tiny pieces that go into it and above all I just wonder how the heck it got like this. Amazing video, a gem of TH-cam.
Back in 1988 I was working as a contractor to Intel and was approached by an engineer looking at a problem they had to address cache memory. On a napkin I had with my lunch one day I scribbled out something similar to this design (but very simplified). It appears that my concept was accepted and multiplied a few million times. Glad I was able to help.
Using photolithography, layer by layer with harsh strange chemicals & very expensive highly specialized tools in building that cost billions with high operating costs that run 24/7
Very very pure water & clean stable electricity are two of the key ingredients + acids & precision polymers & robots & automation of the most precise type for high volume high throughput // to make billions of chips
Thanks to Branch Education Team, being a SSD Firmware Developer it is hard to visualize that how the memory cells behave inside SSD but with animations you created it is became very very helpful to visualize and understand the concepts more clearly. Can you make a video on challenges of developing or using more number of bits to a single cell like TLC, QLC etc. Thanks for the very nice animations.
The first computer I used had HDD and read floppy disks. When the first comercial SSD's arrived they blew everyone's mind how much faster they were compared to HDD, but they were still very expensive and had very limited storage, so the usual solution was to pair a small capacity SSD as the boot partition and a HDD for large volume storage. Today, I am amazed that SSD's have advance far enough that you can do away with slow HDD completely. For the first time, I am using a computer with no HDD at all, and after having been stuck with a slow HDD machine for a while, the speed and comfort this new computer provides is bliss. I still use an external HDD for extra storage, but this will probably be the last HDD I ever purchased. The next external drive, if i ever need one, will be an SSD.
When did you see 12MPx picture taking up hundreds of megabits of memory? Raw from my 14MPx camera is about 12 megabytes (x8 is roughly 100 megabits and even raw often uses some sort of lossless compression algorithm). This calculated size of the picture is stored only in ram.
After seeing your marvellous videos, I started paying huge respect to my mobile and Laptop, and to the engineers and to YOU. These things are beyond description but you splendidly explained it. And the animations are Awesome. It feels that you have spend a lot of time and effort to make these videos. Thank you. I respect you.
And for that work, you (people) pay their wages so they van afford their life plus a meal at McDonald's. So no complain and no regrets, you paid for your memes.
What I find the most mindblowing isn't so much the concept of memory, but the feat of manufacturing these complex structures. I mean, a flash trap has to be the size of what... a fraction of a micron? How do you make something that small, that also has a functon?
Bravo! You take the art of teaching to new heights. Most people can not imagine how many hours of hard work has gone into producing this 17 minutes of extremely information dense educational video. I for one would appreciate if at the end of the video you would add how long it took you to produce this amazing educational content. It is easy to take your work for granted just as it is easy to take the work of those amazing engineers for granted. Thank you sit! I hope the rest of us prove to be worthy of your amazing efforts!
I'm so impressed that how simply you explained one the most complicated and advace engineering technology. Great!! Gave this video a like too.(I give likes very rarely) Great animation+explanation+content. Well done!!
Here I am watching this video a second time on another browser, just to be able to upvote it. I use computers since the 80s but never really thought about how flash memory works and just took it as a given tech´. This video does a good job explaining the technology behind it on a basic level so anyone can understand it. Great job on the visualisation!
Glad you enjoyed it! Yeah! I've used Flash drives / SD cards since when they first came out, and only now, 20 years later do I finally understand how they work.
I believe no University or college can teach such a complex topic in Such an easy and intersting way, Hat's off to you... You have put a lot of effort for this single video...The best explanation of SSD in the whole Internet ♥️ Kudus to your effort ♥️✨
Yeah! I was an engineer for a long time, and I always felt I did so little- I would design just a number of cable harnesses and mechanisms, and it would take me half a year to a year to fully finalize it.
(Long comment incoming, but I really do wholeheartedly mean everything I said here) First time ever doing a paid comment, but I feel like this one is well worth it. I really feel that this video was one of the most enjoyable ones I've ever watched in multiple years of using youtube. It was clear and explained things in an easy-to-understand way that I found extremely easy to understand, and I really found my mind blown away by the sheer scale of this technology (especially in the final chapters). The models and animation are borderline impeccable and (as a visual learner) made the information much easier to digest, whilst keeping everything simplified. I want to support your vision of creating engaging content to educate as many people as possible - I think that's truly a great cause. These 2 pounds are the best way I have of doing so right now. I'm really glad I've discovered this video. Edit: I've just rewatched the video again with the comments, and I feel kind of sad knowing that I won't be able to find many other videos out there that will give me as much of a enjoyable and wholesome experience to this one. I wish I could just magically erase this memory from my brain (maybe with 40v like they use to erase the blocks? lol) just to watch it again for the "first" time (and then again with the comments lol) also I'm starting to wish I went for a higher donation tier, 2 pounds is starting to seem quite stingy for such an amazing learning experience I hope comments like mine reach Teddy (the founder of this channel) so that people like me can let him know how much we appreciate their videos. I doubt that this comment will ever be read by him (as of writing, there are 7,361 comments on this video) but if by any chance, this comment reaches them, let me know. It would make my day.
Thank you for a wonderful video explaining how computer memory works. I am now 61 [in the year of 2021] years old and it took me watching twice just to digest half of the explanation. The patient voice of Phil Lee and superb animation encourage me to watch it again. Yes, I will watch until fully memorized it in order to understand thoroughly, probably it would take me another four or five times...LOL. For now I have to stop and let every steps of the explanation sink in.
Same for myself!An excellent, informative video; great narrative and instructor. Thank you, I hope to view as many as possible (me being computer illiterate) thanks again!
this is the kind of education I love to see, because without being able to independently conceptualize these very small concepts it's easy to get frustrated. I still can't say that I fully understand how this works but what a great explainer!

This is SO incredible. I consider myself a tech enthusiast, and knew that it was very complex, but it's truly shocking how intelligent people are; the designers of SSDs, and their predecessors, are unbelievably brilliant.
It really puts into perspective how far behind the rest of humanity is we all thrive off of a technolgy that only a hand full of humans can even build from scratch. Like monkeys that enjoy macaroni and cheese but have no idea how to make it them selves.
That is also exactly how televisions work, or some "holographic" cubes work. And it is based on how every computer has been working these last 40 years or so
Well this is just covering V- NAND memory there's different types out there that work a bit differently but same general concept
in a matter of years, someone is going to replicate a human mind with the ssd concept.

Every part of smartphone is a miracle of engineering
Most people today : nah, we only care about the camera
seems more like the companies care about having "the best" camera
but in reality, people just want a decent camera - which most higher end phone has these days.
I mean.. can you tell which picture is taken with which phone?
Imagine having a 200 pic collage taken with the top 200 mobile phones, and you just had to guess which phone took which picture. You can't.
this whole "camera race" is lame
My old S7 edge took great pictures and i cant really tell based on my albums when i switched phones (i got the S9 these days - replaced S7 due to screen having "pink lines" for some reason)
That's true- I think this camera push is really driven from the marketing dept. And that the marketing team needs something for differentiation.
@@BranchEducation The Android was originally intended to be used for camera devices so can't really blame them
It's a way for them to make you give them money. Money is want they want in the end.
😂😂though camera indeed too. People only cares about MP😂😂
An additional thing to this video is I read an article about SSD drives that said the controller also keep track of how many times a cell has been used because the number of times a cell can be used is limited compared to traditional hard drives. The controller actually locates the least used cells in memory and that's where it saves information, in other words a file could be all over the place bit by bit instead of stored sequentially.
If every bit of complexity is written down and documented, which I'm sure it is, the resulting amount paper would probably crush me if I got under it
The controller in a HDD does similar things. Your data in the HDD isn't stored sequentially in most cases as well. But sequentially writes (and reads) are faster and therefore preferred when possible.
@@JustSomeGuy009 Yes, correct, so back in the days we used these programs that would rearrange the files they are stored sequentially because with a mechanical read/write head it improved the speed of reading files and also prolonged the life of the drive.
Yes. This is commonly called wear leveling, and it's very important for flash memory cells.
@@JustSomeGuy009 It's really not the same thing at all. For solid state memory, getting blocks in order that way is not especially important, but what is important is not writing to the same cell too many cells over the course of its life. Wear leveling is the usual name, and it's important.

Bravo! As a retired electronics tech, I appreciate discovering these technologies that did not exist when I was studying electronics in 1978!!!
Technology is a very broad concept. The technologies existed. CMOS was invented in the 1960s. Nand Flash memory is a direct development of EPROM. And so on. Basic manufacturing principles also remains pretty much the same. (One example of this continuity: Large parts of the industry switched from metal gates to self aligned gates made out of polycrystalline silicon in the late 1960s, but went back again to metals (cu or al) around year 2000, for better performance in CPUs.) But, sure, the "constant" shrinking (until now!) of transistors has made manufacturing and processing techniques much more elaborate and expensive since 1978.
You guys didn't experienced on your time but take note all improvements currently are just and ideas in your time, and still they are using bit.
in short they can't skip inventing from 1970's directly to 2020
You are not alone mate, I designed a product that first used 1K memory, it was soon replaced by a 4K static ram, then they stopped making those as technology moved on so fast, I had to change my pcb layout to accomodate bigger chip , then that became obsolete and had to use a 16K chip with 15K going to waste, only 1 K being used, so these have become obsolete now for quite some time, over a decade ago, but you can still buy some old stock, so now no one bothers with 128K, or 256K and all of these are now becoming defunct replaced with serial memories, of mega and giga bits!
@@mgabrielle2343 Hmm... Perhaps in the 1970s. But things have been pretty stable since the mid 1980s. You can still buy static RAMs as small as 8Kx8 (i.e. brand new, no old stock). The ubiquitous 32Kx8 SRAM (62c256 an similar) are still considered a standard component, with several different manufacturers over the world.
It's just mind-blowing . An entire galaxy of bits in this tiny piece of silicon.
And Samsung makes quite a lot of these so I guess you could call it the Samsung Galaxy ;)

There is no way this could be explained more clearly, I appreciate this masterpiece! ❤
Ikr
This is an amazing visual explanation.
I worked in flash-based data recovery for 2 years. I was familiar with the logical structures and relative sizes of pages, blocks and banks (the 8 stacks of chips inside the physical package), but I could never visualise them physically before watching this video. At least not the internal structure of the blocks.
I have seen many X-rays of VNAND, and your depiction of the 8 staggered banks top of each other, with the rows of copper wire bonds between them was 100% accurate.
I think I’d love to see your take on how flash controllers work, how they translate coherent binary from say an ascii text file, to the heavily obscured mess that actually gets written to the NAND.
If your file is made up of the binary ‘1010 1010’, that is not the sequence that gets stored physically,
Contiguous logical data like that ‘1010 1010’ sequence will first get split up and scrambled with a XOR pattern, than turns it in to effectively ‘random’ data.
It then gets split across different pages, belonging to different blocks on different banks.
This is called the “flash translation layer”, effectively the layer of logic that converts logical data storage to physical data storage.
All this is done so that any given file is stored in as many separate pages as possible. You can only access one page per block at a time, so it would be slow to have to wait for every page to be read sequentially if your whole file is stored in one block.
Instead, if you split a single file across many blocks and many banks, you can read multiple pages of that file simultaneously, speeding up the read and write processes.
This method of parallelising data access is why solid state drives have become so fast.
Instead of having one person read a 100-page book page-by-page, you split the book up in to 100 separate pages, and have 100 people read a page simultaneously.
Once they’ve each read a page, it’s quicker to rearrange them in to the order of the pages they read, than it would have been to wait for one person to read all 100 pages.
Wow, your comment made me a bit more intelligent 🙏🏼😂

@@chaoticmasterpiece That old Moores law does not really hold anymore. Physical limits in scaling are reached for most kinds of chips. But NAND Flash (used in SSD) are built in multiple layers.

University dissertation?
The first computer I used had HDD and read floppy disks. When the first comercial SSD's arrived they blew everyone's mind how much faster they were compared to HDD, but they were still very expensive and had very limited storage, so the usual solution was to pair a small capacity SSD as the boot partition and a HDD for large volume storage. Today, I am amazed that SSD's have advance far enough that you can do away with slow HDD completely. For the first time, I am using a computer with no HDD at all, and after having been stuck with a slow HDD machine for a while, the speed and comfort this new computer provides is bliss. I still use an external HDD for extra storage, but this will probably be the last HDD I ever purchased. The next external drive, if i ever need one, will be an SSD.

It was clear and explained things in an easy-to-understand way that I found extremely easy to understand, and I really found my mind blown away by the sheer scale of this technology (especially in the final chapters). The models and animation are borderline impeccable and (as a visual learner) made the information much easier to digest, whilst keeping everything simplified.

Thank you for a wonderful video explaining how computer memory works. I am now 61 [in the year of 2021] years old and it took me watching twice just to digest half of the explanation. The patient voice of Phil Lee and superb animation encourage me to watch it again. Yes, I will watch until fully memorized it in order to understand thoroughly, probably it would take me another four or five times...LOL. For now I have to stop and let every steps of the explanation sink in.
Same for myself!An excellent, informative video; great narrative and instructor. Thank you, I hope to view as many as possible (me being computer illiterate) thanks again!
this is the kind of education I love to see, because without being able to independently conceptualize these very small concepts it's easy to get frustrated. I still can't say that I fully understand how this works but what a great explainer!
This is actually one of the best and informative videos I've seen on youtube, describing on how a SSD works.
Thank you so much for this type of content.
Out here educating people.
These are such good videos. I recommend these anytime anyone asks questions about computers
"Magnets" has left the chat.
Haha, poor HDD
PhantomPanic why do magnets suck?
PhantomPanic obviously harder to manufacture lol
this comment did make me laugh out loud...

I absolutely loved this video. I was doing a presentation about ssd's and when I found this video I got even more excited. What an amazing video with so much information. Props to the creator, keep it up
These animations, and what I assume are 3d scans, are incredible! I really respect and admire the level of investment in quality here. Instant subscribe!
