Christopher, I just want to say that I've built my own computers since the 90's. But I only do it once every 5-10 years or so. Back then I bought books, especially "Build your own 386 PC and save a bundle." Each time I went to build a new PC, it got paradoxically harder. The internet had the information, but it was scattered and took a while. Your channel helps a lot for a guy like me who can't spend a lot of time keeping up on the technology. Thanks!
Yeah..actually building your own PC is pretty easy, it's selecting the right parts for it that has gotten harder, between the CPU socket options, RAM types, etc..

You are of great value to people like me who sometimes struggle to keep up.
I can relate to your comments on punch cards, and Mark sense and the TRS computer. I had an equivalent to the TRS which was Australia's answer to the TRS which was the Dick Smith TRS 80. My son learnt programming on this computer at the age of six. His first program was the game meteorite. This brings back fond memories of 4k memory utilisation a tape drive to store programs alot of peeks and pokes.

Thank you for the memories. The computer had a bit of disastrous end. I came home from work and I went to see my son who had dismantled the computer and had the parts all over his bedroom. I said to him well you now understand how to dismantle a computer and is valuable knowledge. That computer never worked again. He went onto design computer farms to render images.

@@ExplainingComputers I used to one the support and development of a transaction processing operating system back in the 1970s which could have over 1,000 online users and had 768 kB of ferrite-store main memory at around 10-12 transactions per second. Something called an ICL System 4, which was a licensed copy of an RCA Spectre which was the first attempted IBM 360 clone (and basically bankrupted RCA). It was a 24 x 7 system with disk mirroring and full, dual transactional logging. It, and a second machine of the same specification provided all the central air cargo handling system for the UK as well as automated customs clearances. It used 3,600 RPM 14 inch 30MB disk packs called EDS 30s. Massive things that the size of curling stones. That system got ported onto IBM mainframes and the same core systems ran until near the end of the century. For some other applications (notably RAF stores management) the operating system ran for another 10+ years beyond that. At the end of my career I was working with machines with 256GB of main memory, 128 CPU cores and disk storage arrays in the petabyte range. So, coming from the days when every bit counted, we are now in an era of profligacy, or so it seems.

If in doubt, I'll visit a dodgy website using a sandboxed web browser or via a virtual machine.
Outstanding. Thanks! I just spent a day figuring out that I could not put an M.2 drive in my machine, and get the performance I hoped for, since my MB doesn't have a second PCIE 2 slot which would be required to support the adapter card properly. And, since the MB only has SATA2, which can't get my SSD anywhere near to it's rated speed, I am now ordering a VERY similar used MB with SATA3, USB3 and digital audio out. All things I want and for a good bit less than a PCIE - M.2 adapter and M.2 drive. Not as fast, but fast enough!
I upload ever Sunday. :) There are several PC build series on this channel -- the most popular starts here: th-cam.com/video/mIQfFIBjfXE/w-d-xo.html And I have a PC upgrade series, starting here: th-cam.com/video/2o-p5Wq6MoQ/w-d-xo.html Good luck!
That part about the interfaces types are well explained 👍 End user need to pay attention especially on those m.2 types I work with one of the storage manufacturer, and the reason why theres so many interfaces (even those SAS and U.2) is because to give options for consumers/data-centers to migrate to ssd while still use their existing HBAs thats probably still under warranty (not all datacenters have the budget of amazon/fb)👌
This channel is massively underrated. His way of to the point explanations also providing revelant side informations and avoiding techincal jargons...what more can I say. I've seen many similar videos, but nothing comes close to his way of explaining things...
@@ExplainingComputers there is this saying here "Kuchto log khyenge, logo ka to kam ha kehna" which basically means "People would say something, it's their duty to speak". One cannot please everyone, and knowing you didn't do them wrong why bother with their remarks (well it is always good to listen to remarks and improve on things). So yes keep on doing what you do and looking forward to more vids!! 😄
Okay, C.B. What's With This, "Let's Go & Get Started" Stuff!?! I Wanted To "Take A Closer Look"! But You're The Man!! I Bet You Could Explain Algebra & Make That Interesting Too!!
I generally dislike when companies break from standard for their own nomenclature, but I agree with Samsung on this one. It's clear that bits per cell will be growing for a while so, rather than forcing customers translate [M,T,Q,P] -to> [2,3,4,5], using "Multi" generically makes more since. In fact I'd argue that we should get rid of the "M" altogether and just straight to 1LC, 2LC, 3LC, .. [n]LC
Although the LC part *also* doesn't make sense because a 2LC flash has 4 voltage levels, not 2. And a 3LC has 8 voltage levels, not 3. They should be called 1-bit cell, 2-bit cell, etc. 1BC, 2BC, 3BC, ...
I'm Illuminated, as usual. When you explain things such as SSDs I can absorb it much easier than trying to plow through it myself. My thanks for this episode and of course all episodes. These are my "go to" videos for all things computer.
As someone who once owned a 5 1/4 inch IDE (PATA) 60Mb (Yes, megabytes) HDD which along with its controller board (itself larger than some desktop motherboards today) was larger than a house brick and weighed about the same, I just want to express my gratitude for today's form factors. 😁
@@Kevin-mx1vi Looking things up, it seems that was called ATA and first used in 87. It was in 94 Western Digital came out with a variation of ATA they called IDE. There improvements of ATA-4 which then used the 80 pin cable. I guess WD continued to call it IDE., but in 2000 they came out with what they called Ultra ATA with 133MB/s transfer speeds.
Your ssd lessons has helped a lot, especially the previous ssd lesson on formatting ssd drives. That lesson came in at the right time. Found out the hard way that ssd drives when purchased are unformatted and don't show up when connected to your laptop, even with magician software already pre installed. Poor documentation from Samsung forced me to return it believing it was faulty. After seeing that video of yours is when I learned about how to format it. Thank-you. A grateful Manitoba Canadian.
And now some companies like Apple solder their SSD NAND chips directly to the laptop motherboard/logic board, rendering storage upgrades (practically) impossible.
not only that but if it fails, the whole computer becomes useless... i dont like apple for many reasons.. now they tie the camera serial number to the board so you cannot even repair THAT..
Things like that are practiced for many years now, i have 7y old ASUS laptop and it has RAM soldering on board, luckily they provided another slot where you can put standard SO-DIMM memory.
This will become standard when the devices get more and more integrated. At some point, you will have just a single chip (or block) unit for the consumer market. No upgrades, no fixes, but cheaper, more efficient and more powerful. Could take some years to get there though.
Awesome explanation Chris 👍 The advent of the SSD and the more often than not ability to double the RAM in older store bought laptops was a game changer and hardware upgrade/ revival blessing
Another excellent video. Not just for those interested in technology, but for all people looking to buy/upgrade a computer. My hats off to you again, sir. :)
I have been searching for an explanation like this for months, since I started my homelab journey and realized what a mistake I had made with my storage choices. This is the best explanation I have seen, and thanks to this video I am subscribing to this channel and taking a look at the suggestion hardware videos (specifically PCIe).
Wow! I recently discovered this channel and it is the best I have ever come across in the explanation of computer technology. The explanations are clear, thorough, and concise . The graphics are outstanding and very well timed with the explanations. The presentor has a a strong breath of the subject and speaks with a great cadance. This is truly top of game speaking from the perspective of 35+ years experience in the professional tech industry!
Thank you good sir, this video has cleared up a lot of misinformation I have either been given, or presumed on my part. I feel much better armed with this information in selecting, and purchasing a new SATA SSD upgrade for my Dell Latitude E6430. Once again thank you for all you do in teaching us your viewing public.
Thank you for making this video. I have been trying to look for clear explanation of these difficult terminologies online but only to get more confused as I read them. Your video has definitely made this concepts so much clearer and easy to understand. GREAT JOB!! Subscribed.
I purchased an mSATA to M.2 converter card for an older iMac (late 2013) that was originally setup as a hybrid drive. I breathed in new life into the machine and am typing this comment from it. The HDD was replaced with an SSD 2.5in with a SATA interface, but this made a huge difference in speed overall: the boot drive is a 1TB (the mSATA >M.2) Samsung EVO 980 and the, formerly a harddrive, is now an EVO970 (also 1TB). I can probably use this machine for a few more years (although still stuck with DDR3 memory).
I swear, Mr Christopher Barnatt has the most honest and true look as well as an honest and true-sounding voice. One would be hard pressed to disbelieve anything he says. Honestly, even if he did an advertisement, I'd buy the product simply because he said so haha. Definitely one of the more calming people to listen to when it comes to tech channels.
I have two 2280 M.2 on my laptop and they are fast. Things have changed so much when I built my first computer which was a 386 as its so easy nowadays.
In 1982 I designed and built 8 bit memory cells and at the time they had 2000 ns, all hand wired. I was going to 12 bit even 16 bit but it was at time was to complicated to wire input amps and 65536 output amps. The where chips could do 12 bits a/d but they were 1/10 second and cost $400 a piece. I had 8 of them in a machine that weighted up to 3 lbs. They were weight vegetable memory cells ;.)
My first experience with SSD, was a Mini PCIe in the Dell Mini 9 Netbook in about 2008. A big UK supermarket online shop (now defunct) had a sale on them, it became popular to hack to OSX Snow Leopard with an Install DVD purchased from Amazon. Videos on youtube showed them booting faster than genuine Macbooks of the day. The standard STEC SSD was only 4GB running UBUNTU. It was common to order a bigger and faster 'RunCore 32GB' from the USA to perform this hack, the RunCore came with a Micro USB socket to help format or file transfer. I did mine without the use of a Mac which was tricky to say the least. I still have the original 4GB drive in a pot somewhere.
@@Sup_D No idea why U.2 connects are available on mainstream board, but there are no consumer drives that uses U.2, only Enterprise drives (both HDD and SSD).
Good sir, your videos are always the highlight of a nice weekend. From the synthy intro, to your relaxing explanations, it's a treat. Keep up the wonderful work!
In the past (pre-2000s), we generally have kept a home computer 5-10 years. As retro computing and collecting old computers have become a thing, and backwards compatibility of the OS has been unreliable, the legacy hardware can be expected to run indefinitely, thus I would personally find drives with the maximum life span possible as my selected choice, provided the OEM company offers it as an option. The HHD gradually failing in our first home computer, an IBM compatible, was one of the deciding factors in whether we kept the computer, or donated it to the school (as an alternative to scrapping / recycling). It made sense at that time, but in retrospect I definitely regret having given up that computer-it had historical significance as well as my personal nostalgia. Not all software and updates are available on the internet, thus some things I've wanted to keep have become lost forever as I wasn't able to copy it to a reliable drive.
My SSD is from 2012 ,an old 128GB OCZ and my HDD is from 2009 , a 1TB Seagate baraccuda. Used every day, I think I hit the hard drive jackpot. Going to upgrade to a 500GB PCIe SSD soon! Great video.
Wow, I miss the old days of just having PATA or SATA HDD's.... It's great we have speed and capacity these days, but the technobabble is strong :-) But you went a long way to explain... so thank you Christopher! I think the Samsung way is kind of better in clarity, but, I am still an old duffer who uses SATA :-)
Not the subject of this video! But I do have an episode on "SSD Life Expectancy": th-cam.com/video/-XZNr7mS0iw/w-d-xo.html On your second point, I would consider "data recovery if an SSD does dead" to be a non-issue. If any drive fails -- SSD or HDD -- data is restored from a backup. Nobody should be wasting time and money trying to recover data from a failed drive.
This video couldn't have been timed better with the new PS5 and Xbox Series S/ X consoles now utilising mass storage SSD's for the first time. I even learnt a few new things so the video is highly appreciated!
Of course. Gamers will kill there ssd drives faster than a normal person. Because some gamers downlaod ton of games every day and then format it and download it again.
It does sound worrying to begin with, but when you think about it, even if you have to replace your SSD after 5 years, it's not that bad. Even replacing my fancy expensive drives, imagine how much better and cheaper the replacement will be in five years. I'll probably want more than just a new drive by then, anyway.
Again, thanks for a very informative video, subscribed too. I am thinking about upgrading my PC and this information gave some points to think about and ideas to consider. Now just need to see if finances will also agree with those ideas. The everlasting struggle between ideas and means...
I remember the 60MB 5.25 "brick" HDD I hade as the first one on my old Amiga. Much like floppies, I commonly download files larger than the entire capacity of that storage now...
Back in the mainframe days we had big disk drives the size of a washing machine, and the storage medium was a disk module with a set of about 5 or more 14 inch platters with an iron oxide coating for the data storage. A big one like this held an amazing 300 megabytes of data. When the computer was busy doing a lot of data transfer, the read/write heads would dance back and forth with enough momentum to even shake the disk drive. flic.kr/p/7zuKiQ
I freaking love this channel. I'm trying to inform myself about different types of SSDs for my laptop and he's already done a vid on the subject 3 years prior.
@@ExplainingComputers ..(*sound of 2 drums and a cymbal falling off of a cliff..*) There are a lot of interesting alternatives for data storage, but be aware of the drawbacks, too...like the clay tablets someone mentioned above, data density is rather poor, plus you have the needle-wear degradation problems when you use them often. :-) (As far as oddball techs go, I've always been fond of the internet via messenger pigeon protocol...I wonder if anyone's ever worked on the speed and reliability issues with that? :-) )
Well...maybe... until someone jumps on the floor or bumps your storage device and the needle jumps a groove leaving a scratch behind. Good luck getting that needle to track correctly from now on. :)

@@AnthonyElsom Excellent, my man. There's so much negatively surrounding using Windows 7 still but honestly I see no cause for concern. I mean the internet is literally the only access point for potential viruses or exploits and I'm buggered if I'm going to change my whole ecosystem and methodology just for one small factor like that. If in doubt, I'll visit a dodgy website using a sandboxed web browser or via a virtual machine.
Outstanding. Thanks! I just spent a day figuring out that I could not put an M.2 drive in my machine, and get the performance I hoped for, since my MB doesn't have a second PCIE 2 slot which would be required to support the adapter card properly. And, since the MB only has SATA2, which can't get my SSD anywhere near to it's rated speed, I am now ordering a VERY similar used MB with SATA3, USB3 and digital audio out. All things I want and for a good bit less than a PCIE - M.2 adapter and M.2 drive. Not as fast, but fast enough!
That was the clearest most straight forward explanation of SSDs I have yet heard! Excellent by any standard!
Excellent and useful content. Very professional, well explained and straight to the point. Thank you very much.
Address the point right away, no dummy introductions. Excellent!
Thanks.
hope this guy still uploads vids. i don't know how to build pc or know anything about it, but by watching this, i get some good info Thanks Master!
I upload ever Sunday. :) There are several PC build series on this channel -- the most popular starts here: th-cam.com/video/mIQfFIBjfXE/w-d-xo.html And I have a PC upgrade series, starting here: th-cam.com/video/2o-p5Wq6MoQ/w-d-xo.html Good luck!
That part about the interfaces types are well explained 👍
End user need to pay attention especially on those m.2 types
I work with one of the storage manufacturer, and the reason why theres so many interfaces (even those SAS and U.2) is because to give options for consumers/data-centers to migrate to ssd while still use their existing HBAs thats probably still under warranty (not all datacenters have the budget of amazon/fb)👌
Old-timer here, in computers since the early 70s. This is a great overview of new storage technologies that are difficult to keep up with. Thanks.
This channel is massively underrated. His way of to the point explanations also providing revelant side informations and avoiding techincal jargons...what more can I say. I've seen many similar videos, but nothing comes close to his way of explaining things...
Thanks for this. I am getting some very negative feedback today, so you kind works are very much appreciated.
@@ExplainingComputers there is this saying here "Kuchto log khyenge, logo ka to kam ha kehna" which basically means "People would say something, it's their duty to speak". One cannot please everyone, and knowing you didn't do them wrong why bother with their remarks (well it is always good to listen to remarks and improve on things). So yes keep on doing what you do and looking forward to more vids!! 😄

Your video removed many of my confusions about SSDs
I generally dislike when companies break from standard for their own nomenclature, but I agree with Samsung on this one. It's clear that bits per cell will be growing for a while so, rather than forcing customers translate [M,T,Q,P] -to> [2,3,4,5], using "Multi" generically makes more since.
In fact I'd argue that we should get rid of the "M" altogether and just straight to 1LC, 2LC, 3LC, .. [n]LC
Although the LC part *also* doesn't make sense because a 2LC flash has 4 voltage levels, not 2. And a 3LC has 8 voltage levels, not 3.
They should be called 1-bit cell, 2-bit cell, etc. 1BC, 2BC, 3BC, ...

wow
This cleared up a lot of confusion i appreciate it
I'm Illuminated, as usual. When you explain things such as SSDs I can absorb it much easier than trying to plow through it myself. My thanks for this episode and of course all episodes. These are my "go to" videos for all things computer.
Very comprehensive and clear explanation. Thanks 🙏
As someone who once owned a 5 1/4 inch IDE (PATA) 60Mb (Yes, megabytes) HDD which along with its controller board (itself larger than some desktop motherboards today) was larger than a house brick and weighed about the same, I just want to express my gratitude for today's form factors. 😁
Indeed my first harddisk was the size of an industrial scale
The first drive i put my hands on was a 9427H-C Hawk CDD. Storage space until the end of time. I thought ... ;- )
I think those were MFM, not IDE
@@knerduno5942 Definitely IDE - I had it connected to an Amiga that had an IDE interface.
@@Kevin-mx1vi Looking things up, it seems that was called ATA and first used in 87. It was in 94 Western Digital came out with a variation of ATA they called IDE. There improvements of ATA-4 which then used the 80 pin cable. I guess WD continued to call it IDE., but in 2000 they came out with what they called Ultra ATA with 133MB/s transfer speeds.
the best SSD explaining video on the internet
Thanks. :)
One of the best videos on the subject currently on youtube. Clear and structured. Thank you for making it easier to understand for so many of us👍
Thanks. :)
Your ssd lessons has helped a lot, especially the previous ssd lesson on formatting ssd drives.
That lesson came in at the right time.
Found out the hard way that ssd drives when purchased are unformatted and don't show up when connected to your laptop, even with magician software already pre installed.
Poor documentation from Samsung forced me to return it believing it was faulty.
After seeing that video of yours is when I learned about how to format it.
Thank-you. A grateful Manitoba Canadian.
Other channels drown you in jargon - Explaining Computers does just that - explains how things work, and makes sense of the jargon. (Thank you!)
Awesome video! This explained SSD's in a way that I can understand better than most.
And now some companies like Apple solder their SSD NAND chips directly to the laptop motherboard/logic board, rendering storage upgrades (practically) impossible.
not only that but if it fails, the whole computer becomes useless... i dont like apple for many reasons.. now they tie the camera serial number to the board so you cannot even repair THAT..
Things like that are practiced for many years now, i have 7y old ASUS laptop and it has RAM soldering on board, luckily they provided another slot where you can put standard SO-DIMM memory.
Very true -- not a great practice at all.
Just more reason not to buy Apple and into their walled gardens.
This will become standard when the devices get more and more integrated. At some point, you will have just a single chip (or block) unit for the consumer market. No upgrades, no fixes, but cheaper, more efficient and more powerful. Could take some years to get there though.
As always, your videos are very informative; just the very salient points.
Awesome explanation Chris 👍 The advent of the SSD and the more often than not ability to double the RAM in older store bought laptops was a game changer and hardware upgrade/ revival blessing
Well that's not so hard. Thanks for making that perfectly clear. Clear English AND clear enunciation much appreciated also sir.
Another excellent video. Not just for those interested in technology, but for all people looking to buy/upgrade a computer. My hats off to you again, sir. :)
Many thanks.
I have been searching for an explanation like this for months, since I started my homelab journey and realized what a mistake I had made with my storage choices. This is the best explanation I have seen, and thanks to this video I am subscribing to this channel and taking a look at the suggestion hardware videos (specifically PCIe).
Please do a video on IOPS, read/write speed, seek time for HDDs, and what you'll actually need for which types of applications.
Neat idea, noted.
Great Video Chris.
This information tells me that I might have options for my WIFI slot even though you did not discuss those types of slots.
Very true.
Thanks. I'm going to upgrading a desktop with an SSD and this was helpful.
Wow! I recently discovered this channel and it is the best I have ever come across in the explanation of computer technology. The explanations are clear, thorough, and concise . The graphics are outstanding and very well timed with the explanations. The presentor has a a strong breath of the subject and speaks with a great cadance. This is truly top of game speaking from the perspective of 35+ years experience in the professional tech industry!
I love SSD. Just upgraded my favorite notebook with one, and will be able to get a few more years out of it.
Thank you very much for the clear precise information. For the history and the current options. Thanks.
Thank you good sir, this video has cleared up a lot of misinformation I have either been given, or presumed on my part. I feel much better armed with this information in selecting, and purchasing a new SATA SSD upgrade for my Dell Latitude E6430. Once again thank you for all you do in teaching us your viewing public.
thanks man this is the video that cleared all my confusions about ssds!

I purchased an mSATA to M.2 converter card for an older iMac (late 2013) that was originally setup as a hybrid drive. I breathed in new life into the machine and am typing this comment from it. The HDD was replaced with an SSD 2.5in with a SATA interface, but this made a huge difference in speed overall: the boot drive is a 1TB (the mSATA >M.2) Samsung EVO 980 and the, formerly a harddrive, is now an EVO970 (also 1TB). I can probably use this machine for a few more years (although still stuck with DDR3 memory).
Extremely interesting and informing, no bullshit, amazing!
Thanks.
@@ExplainingComputers You forgot to mention SATA DOM's.

I have two 2280 M.2 on my laptop and they are fast. Things have changed so much when I built my first computer which was a 386 as its so easy nowadays.
In 1982 I designed and built 8 bit memory cells and at the time they had 2000 ns, all hand wired. I was going to 12 bit even 16 bit but it was at time was to complicated to wire input amps and 65536 output amps. The where chips could do 12 bits a/d but they were 1/10 second and cost $400 a piece. I had 8 of them in a machine that weighted up to 3 lbs. They were weight vegetable memory cells ;.)
Wow. Not that many years ago.
Bare transistors, or were you old enough to work with core memory?
@Robert Slackware Just imagine weaving them all by hand.
@Robert Slackware Magnetism follows the same inverse-square law that light and gravity do. Neodymium magnets aren't THAT powerful.
My first experience with SSD, was a Mini PCIe in the Dell Mini 9 Netbook in about 2008. A big UK supermarket online shop (now defunct) had a sale on them, it became popular to hack to OSX Snow Leopard with an Install DVD purchased from Amazon.
Videos on youtube showed them booting faster than genuine Macbooks of the day. The standard STEC SSD was only 4GB running UBUNTU. It was common to order a bigger and faster 'RunCore 32GB' from the USA to perform this hack, the RunCore came with a Micro USB socket to help format or file transfer. I did mine without the use of a Mac which was tricky to say the least. I still have the original 4GB drive in a pot somewhere.
Thanks Christopher, i was actually confused about the difference between NVME and Sata.
And you were not alone!
Same, had a lot of confusion relating to M.2 Sata and M.2 NVMe.
Also, i didn't even know about U.2 SSD's.
@@Sup_D No idea why U.2 connects are available on mainstream board, but there are no consumer drives that uses U.2, only Enterprise drives (both HDD and SSD).
@@AlfaPro1337 Cost issues maybe?
Good content for many of those looking to upgrade to an SSD or upgrade their existing SSD. Thank you

Many thanks!
In the past (pre-2000s), we generally have kept a home computer 5-10 years. As retro computing and collecting old computers have become a thing, and backwards compatibility of the OS has been unreliable, the legacy hardware can be expected to run indefinitely, thus I would personally find drives with the maximum life span possible as my selected choice, provided the OEM company offers it as an option. The HHD gradually failing in our first home computer, an IBM compatible, was one of the deciding factors in whether we kept the computer, or donated it to the school (as an alternative to scrapping / recycling). It made sense at that time, but in retrospect I definitely regret having given up that computer-it had historical significance as well as my personal nostalgia. Not all software and updates are available on the internet, thus some things I've wanted to keep have become lost forever as I wasn't able to copy it to a reliable drive.
That's interesting just a few days ago I worked on a Dell that had a 1630,
at least it was a Wi-Fi module b-key.
Never seen one in the wild till now.
Thanks for the very detailed video of the various types of SSD's.
Maybe in another video you can discuss the value of DRAM and SLC cache and the lack of these in some SSD drives.
Thanks and noted. :)
My SSD is from 2012 ,an old 128GB OCZ and my HDD is from 2009 , a 1TB Seagate baraccuda. Used every day, I think I hit the hard drive jackpot. Going to upgrade to a 500GB PCIe SSD soon! Great video.
SSD’s the alphabet soup of storage devices. I wonder what will be available for us in the next decade? More speed, more storage, more acronyms?
Talking about alphabet soup, don't get me started on USB.
I wish I saw this as the first material when researching the M.2 / NVMe topic
Imagine this man is Linus Tech Tips's mentor and Linus features him in one of their videos......
I would rather have the Professor make an appearance on RMC The Cave, as they are both out of jolly England.
Thanks, actually watched the entire video.
Easy to learn from you.

Awesome, thank you!
Wow, I miss the old days of just having PATA or SATA HDD's.... It's great we have speed and capacity these days, but the technobabble is strong :-)
But you went a long way to explain... so thank you Christopher!
I think the Samsung way is kind of better in clarity, but, I am still an old duffer who uses SATA :-)
IDE master slave settings that's how it's done. You kids with your fancy sata cables!
I love your complete and clear explanations. You are a goto guy!
For 2021, I'd like to see more NVMe on SBC. No more eMMC and MicroSD. pls
emmc you mean ?
got my raspi hooked to an sata ssd with the Argon M.2
The difference between this and other tech channels is that this actually teaches you whereas the other ones just show you cool tech.
Anything less than TLC is very volatile. You should have talked about data retention capacity and data recovery if an SSD goes dead.
Not the subject of this video! But I do have an episode on "SSD Life Expectancy": th-cam.com/video/-XZNr7mS0iw/w-d-xo.html
On your second point, I would consider "data recovery if an SSD does dead" to be a non-issue. If any drive fails -- SSD or HDD -- data is restored from a backup. Nobody should be wasting time and money trying to recover data from a failed drive.
This video couldn't have been timed better with the new PS5 and Xbox Series S/ X consoles now utilising mass storage SSD's for the first time. I even learnt a few new things so the video is highly appreciated!
Thank you very much kind sir!

The write-rewrite cycles sound concerning....Won't gamers degrade their ssd's faster? I dont know much but id like to know more.
Of course.

@@ExplainingComputers Thanks! Going straight to it!!
It does sound worrying to begin with, but when you think about it, even if you have to replace your SSD after 5 years, it's not that bad. Even replacing my fancy expensive drives, imagine how much better and cheaper the replacement will be in five years. I'll probably want more than just a new drive by then, anyway.
@@ExplainingComputers That video definitely calmed me down. No panic!
Edit: Still don't understand over provisioning though.

Why was the name "DLC (Dual Layer Cell)" not used?
You can if you want .
In retrospect, this would have been very sensible!
So much information in 14 minutes! I was surprised how much I learned about a topic I thought I was more than just vaguely familiar with.
You didn’t even mention 5 1/4 inch hard drives. They were used for years.
I remember the 60MB 5.25 "brick" HDD I hade as the first one on my old Amiga. Much like floppies, I commonly download files larger than the entire capacity of that storage now...
Back in the mainframe days we had big disk drives the size of a washing machine, and the storage medium was a disk module with a set of about 5 or more 14 inch platters with an iron oxide coating for the data storage. A big one like this held an amazing 300 megabytes of data. When the computer was busy doing a lot of data transfer, the read/write heads would dance back and forth with enough momentum to even shake the disk drive.

There are a lot of interesting alternatives for data storage, but be aware of the drawbacks, too...like the clay tablets someone mentioned above, data density is rather poor, plus you have the needle-wear degradation problems when you use them often. :-)
(As far as oddball techs go, I've always been fond of the internet via messenger pigeon protocol...I wonder if anyone's ever worked on the speed and reliability issues with that? :-) )
Well...maybe... until someone jumps on the floor or bumps your storage device and the needle jumps a groove leaving a scratch behind. Good luck getting that needle to track correctly from now on. :)
