Well, I can relate! I'm 73 and I've been at it for 25 years, so we must've gone to different schools together! That video helped me a lot....I wasn't up to snuff on those storage options either. I sure don't miss those IDE cables!
Hey sir, the ADATA xpg 8200 pro m.2 NVME is at a great price! Check it out. Pure raw performance rivaling the Samsung 970 pro but a fraction of its cost. I would love to be able to tinker with hardware when I am at your age! Must have great stories and interesting hardware over the years of your builds. I am way younger than the entirety of the duration you have built PC! Have a nice day!
One point of order - Originally, the flat 40/80 pin cables were NOT called PATA ( PATA is a retronym ), they were referred to as IDE or just ATA and only renamed as PATA after SATA became available.
Well pointed out. I've plugged in quite a few IDE cables. But mainly I'm replying to praise the word 'retronym.' Never heard it before, and it's a beauty for this linguaphile. ;-)
As your signaling frequency goes up, the distance between the wavefronts on the parallel interface become harder to synchronize. As a result, you have to build in delays in the protocol resulting in efficiency in transfers. Going with parallel/serial allows you to have several synchronized serial "lanes" that don't necessarily have to be time-synchronized on the wavefront for signal clocking. So PATA became SATA and SCSI became SAS - and PCI became PCIe...
Love your succinct but clear explanation. I'm an old techie, too, I still remember pushing RAM chips into my first 8 MB motherboard and the HUGE upgrade from my 20 MB MFM hard drive to the big 60 MB RLL.
I also remember the RAM boards with the reams of chips and when they would stop working, just reseat the chips and be on your merry way. dust was not your friend.
Being in IT for a long time, I have to say that this is a great video. I don't miss the days of IDE cable management. It's also nice that motherboards are much more clearly labeled now than they used to be.... :)
Yea.. worst part I remember about computer setup, apart from those AMD processors that required you to nearly jam a screwdriver through your motherboard in order to install the heatsink, was sitting there with a flashlight at odd angles, trying to see those microscopic letters on the board, to figure out where to put the stupid tiny wires just so the power/restart button on the case would work.
Make sure you've got the master/slave jumper set correctly on the back of EACH drive connected to the IDE cable or your 4x CD-ROM Drive simply will not compute (you can always opt to plug this directly into your ISA Sound Blaster Card :P)
I, too, started in IT in the "ESDI/MFM/RLL/SCSI" era, but retired about the time these SSDs really began replacing the ole "spinning rust" drives, thus I was pretty much in the dark regarding the M.2 SSD's. Subscribed and thanks for enlightening me!!
Thanks very much for this info. I’ve had an NvME drive in my system for nearly 3 years and had my M.2 slot set to SATA as my ASU’s Z170 board has that as the default setting because there isn’t an auto option. My system is noticeably snappier loading and opening apps now.
Great explanations, when I saw those old cables it brought back memories of trying to build my first PC, having to run a jumper on certain pins depending on the hardware and setup. Thank god one of my roommates was an engineer with a lot of patience.
I must admit I know the differences between M2 SATA & NVME, but you still went above and beyond on the details. I still learned something I didn't know before. Kudos on covering this topic. Well done! I will check out your other content.
The way you talked and explained, it felt like a very close person was speaking to me about something we both love. Thank you kind sir. You got my subscription!
Love the history lesson, My first homebuild had a 10MB Stepper motor HD that connected to a card rather than the MoBo. My fourth build had all SCSI-2 interfaces. My next build will have NVMe M.2 Boot drive, on an x16 interface.
Damn, this vid was so straight forward and super informative. No sponsors and no ads he just wants to help explain to those who did not understand. Salute to you king
I still have my old tower with a amd semperon and all the glory of IDE....really been thinking about dragging it out just to try to install windows 10 on it...lol
Lol, i still have my IDE drive in my PC, just because it works (after 7,2 years of power on, and about 15 years since i bought it) and because i can :D
I never liked IDE but it brings back some fond memories of when I was just a kid tinkering with old computers and teaching myself how they worked. Up until now I've always had old hand-me-down computers, so I've become very familiar with the old interfaces. Only when I built my first computer last year did I upgrade from IDE. I skipped SATA altogether and went straight to m.2 and NVMe. I now have a SATA drive as well and I was surprised how easy it was to connect. Just two small cables, no jumpers, and effortless cable management.
Ah yes. "When I was just a kid..." 1980ish messing with an 8K Commodore computer using a cassette recorder data storage. Yes, exactly the same cassettes we used for music. Things have changed quite a bit since I was a kid.
I don't miss being on hands and knees looking for the little jumper that sets the master/slave. Drop it once, it will bounce to the most improbable place...
@@BLKBRDSR71 I think you're referring to hard drive head seek sound and it depends on the drive. Samsung Spinpoint drives click, whirr, clunk and grind a lot even SATA whereas WD drives are almost silent
I just found out about M.2 SSD about two weeks ago. I'm amazed you knew all this in 2017! The video is very informative and you explain everything in a way that's very understandable and eloquent. The humor is a definite plus, too!
Yes! Very well done sir, and extremely useful for me. I've been seeing prices start to go way down on these devices, but I was having a hard time figuring out the format of the hardware. The whole "M.2" nomenclature is quite confusing, but you helped me out A BUNCH! Thanks so much :)
I've never felt the urge to like a video and subscribe to a channel more quickly. What an amazing explanation, with no computer elitism and so much wholesome fun and enthusiasm. Thanks for being such a wonderful host! (:
This is my first time installing an NVMe on my new build. Been using HDDs for the past 20 years. I've watched many videos on youtube about NVMe SSD. So far yours is the easiest to understand 👍
@@yummyramen2821 yeah but believe it or not I've had more Sata cables go bad then I ever had ide cables go bad, the ends of the connectors are very fragile on sata
Your explanations are probably the best I've ever heard, plus I've also learned more from your other viewers' comments! Fantastic. Subscribed, and will return often. Thank you Carey AND other viewers!
I know this is 3 years old & tech has moved on but I'm playing catch up! You're like that one decent teacher at school (long long time ago!) that actually had a passion & an interest in their subject, they explained & taught in a way that not only made facts interesting, those facts sunk in to my thick head & more importantly STUCK cos I enjoyed the lesson! Another great vid Carey 😊
I’m an old timer too, DOS=Damn Old System. Thanks for the video it makes a lots of sense. I liked the small SATA cables, having built many machines wrestling with the old parallel IDE cables, but being an old tech I knew that parallel can be faster. Now that it’s down to the drive being a small circuit board mounted to the motherboard the old hard drive bottleneck which is a decades old problem is mostly resolved.
Once again, another great educational video. The transition from MFM to RLL was painful for some of us. Got stuck with a case worth of Miniscribes when the company went bankrupt.
I have "mantled" and dismantled so many computers in my day, and lately find myself swapping M.2 SSDs dozens of times per week (we manage a park of around 6800 end-user computers) and now knowing this I am better able to understand the dos and don'ts - Thank you for the clarification!
Brother, watching this video is like taking a trip in a time machine to my own youth. Love the Shirt!! I just found you today and I love your low-key and detailed presentation style. You are a natural teacher and you deserve a dedicated video production studio.
Hey, Carey. Tomorrow night I'm helping my buddy build his first gaming computer. It will be the first one I've ever built and we're going to use your videos as a guild. Thanks for all the information to make this build possible.
I would have loved to have had you as a teacher back in the day. I like the "info-tainment" channels like Jayztwocents and all, but sometimes you just need to have the facts explained to you in a no-nonsense way that's easy to understand. You deliver that perfectly.
I quit building PCs during the IDE era and had a heck of a time configuring an m.2 raspberry pi, ordering wrong parts from eBay, etc. This video completely clarifies everything. Thank you.
I just ordered a new 2TB NVMe M.2 SSD after checking everything, and just realized I forgot to double-check the pin arrangement on the actual motherboard! But thanks to your video, I now know that I got the exact right drive. The retailer/assembler put a regular SATA drive in the SATA3_1 slot, so I’ve been using the slowest storage speed my PC can offer… and with only 250 GB of storage. Now I’ll be getting ten times the speed for ten times the capacity! The new drive wasn’t expensive, either. Now I just need to check that BIOS setting when it arrives, and I’ll be good to go. It’s always good to check this stuff so you don’t miss out on things you already partially paid for :D
Thanks for the great video.. Regarding serial vs parallel buses, I believe the speed potential of each is not so clear cut. From a naïve view, parallel buses should be capable of transferring more bits per clock cycle at the same clock speed that serial buses are capable of. But in reality, clock skew becomes a problem for parallel buses, which is the problem of signals arriving at slightly different times on different lines of the bus. This problem is exacerbated with more lines, and with physically flexible buses. This limits the smallest time of a single clock cycle of a bus to be greater than the minimum variability in the transmission times across the lines of a such a bus. In contrast, while serial buses transmit fewer bits per clock cycle than parallel buses, they are capable of a higher potential clock speed because they are less susceptible to the problem of clock skew. Then low voltage differential signalling (LVDS) was developed, which introduced the revolution of very high speed serial connections, as seen with USB, FireWire, etc. With LVDS, a bit in a serial line is transmitted with its inverse, requiring two wires for one bit. The received signal is understood as the difference between these two lines. This has the effect of cancelling out electrical noise, which should effect both lines pretty equally. On top of that, the two wires carrying such pairs of inverted signals are twisted, meaning that the mathematical area enclosed by the two wires is very close to zero, since the sign of the area of each subsequent "loop" between each twist alternates between +1 & -1,and the areas of all the "loops" are quite similar. This leaves a net area with which to pick up magnetic noise close to zero. Thus, magnetic noise is greatly reduced, too. In such arrangements, there isn't even a separate clock line, eliminating the possibility of clock skew between the clock line itself and the single, serial signal. Instead, the clock is inferred from the data signal. The speed potential of LVDS serial lines appeared in things like SATA and serial SCSI - serialised versions of older, parallel standards. In the case of PCIe, each "lane" is an LVDS serial connection, albeit without the possibility of twisting pairs to reduce magnetic noise. Each lane runs at somewhat separate clock speeds, notwithstanding the fact that there's a very fine limit on how different those speeds can be. Data is sent serially down each PCIe lane at one or more bytes at a time, depending on the exact standard. Sequences of data are split and sent down multiple PCIe lanes, in the case of "x2" & greater PCIe arrangements, roughly in parallel. Within the fine limit within which signal skew can be tolerated across multiple lanes, circuitry reconstitutes the data in the right order. So even though PCIe can have multiple lanes, it is still not a truly parallel bus. It's a roughly parallel set of serial connections, each seeking to exploit the high speed advantages of LVDS.
Having juggled with ATA cables for the better part of my youth, I found this explanation so easy and direct, with none of the marketing jazz and distractions from the central point of the upgrade.
Molex Plugs, they either get stuck into a drive or fall out of a drive. You guys forget about "Micro Jumpers" and SCSI, I/O Addresses, IRQ conflicts with sound cards or com ports, and Device ID Nightmares. I do miss the old MFM and RLL "jet turbine" sound effects though.
I would just like to say I found this video to be very informative, as this is my first time as a viewer i have definitely clicked the subscribe button. Thanks
It’s been 20+ years since I have built a computer. Now I have a teenager that wants a gaming pc. I have the foundational understanding of how to to build one but did not comprehend the new technology, until this video. I remember the days of master/slave and SCSI drives. Thank you for this video
I'm trying to build my first computer and thoroughly trying to research what all these acronyms and numbers mean and what they actually mean in layman's terms. This video helped a lot. Thank you for the great explanation and background information!
Your detailed computer build videos and tips helped me a lot while building my own PC. Thanks for the sincerity and effort you put in making those incredibly instructional videos.
Thanks for this explanation. It is so simple even a three-year-old kid would understand. Exactly how it should be explained without unnecessarily complicating things.
Hello from Brazil! I've been watching tons of vídeos to check these differences explaned and you were the only one who was able to explain it in a way I could understand. Thanks!
I always remember using those IDE cables that has to reach the master drive, slave drive and still reach the MoBo.. and many times it was a tight fit without a centimeter to spare.
Thank you so much for posting this video! I'm one of those "old schooled" who started putting rigs together since the 1990's (early 1990's) and I know about the PATA vs. SATA cabling nightmares, etc. There are a lot of videos out there that attempt to clarify the M.2 vs. NVMe confusion but after watching them, it leaves even more confused. This video was very well made, with great and quick intro explanation as to the development of the different technologies and the actual visuals with sizes and installations--and compatibility issues, including the very important BIOS setup! Thanks again, and keep up the good work!
GREAT video!! I've watched ~4 videos and read SEVERAL articles on this, as I am completely new to this... yours instantly made it click! Going back to the roots was the PERFECT way to explain it, thanks man!
I have no doubt that you are an educated person. I love it when I listen to someone knowledgeable and he knows what he talking about. I really appreciate this lovely video. Thanks
Best explanation I ever heard. In 50 years, I never unnderstood it as you just explained. Thank you. You understand, you work it, and you teach it, 🌟 🌟 🌟 .
Most excellent clarification. I was getting mad trying to insert a 2019 NMVe card to an Alienware that apparently only takes M.2 (SATA) cards with two notches. P.S. Nice time capsule with the Origami PATA cables of old. And yes, they did messed-up airflow in a gaming rig.
I actually hope someone familiar with computer memory and bubble gum formulae stumbles in here. Maybe they can explain how to store more than one bit per bubble which would be eight sticks/chewers per byte.
Best explanation I had seen on youtube. And I am including all those made in this 5 years gap since this video was made. I wanted to leave a comment and I am hoping that you still make videos like this. Now I have to go to suscribe... cheers!
Holy Cow, this is an incredibly great video. I have found this M.2 vs NVME very confusing, but you have done a brilliantly clear job of explaining it. I used to build computers with PATA, etc. but lately only buy used HP Z workstation for myself and my clients. Getting older ones without mboard M.2 NVME sockets equipped with an adapter so they boot the OS can be a headache because of adapter compatibility. As for gaming, I used to setup DOOM Novell networked for 3 computers on my home office, I wonder if that's what you were referring to. PS I like your gas range and exhaust system too! Thanks a lot.
@@gerald8573 I mean, yeah, and you could probably carve a few characters onto it with a toothpick, or something. So it's not like it can't store ANY information.
Great video - I think your's is the best at explaining the differences..... Just off to make sure my BIOS isn't set in auto... Which I am 99% sure it is :(
Hi. Great video! No you did not confuse me. I’m an old school computer guy too, so the fact that you went back to hay day of IBM and the crazy connections we had to deal with, that actually helped me. Now I know what I’m buying when it comes to PCiE in the realm of storage. Thanks.
This is by far one of the best videos I have watched. Very well explained. I built a few computers and didn't even know there was a difference till today. Thank you
I'm running 2x 970 Pro on RAID 0 on an Asus Z370-i.... love it... Don't think I will ever use SATA SSD or spinning drives on anything but backup/archives/NAS again.
I remember going from IDE HD to a lower level SATA it was impressive. Than the lower level SATA HD to a SATA 3 SSD even more impressed. Than from the SATA 3 SSD to a M.2 NVME and was blown away. It still amazes me and I upgraded ~Sept 2019. Some game times went from 3-5 minutes down to ~20 seconds.
Very good and clear explanation of the various formats. I used to work as a repair technician and can remember floppy drives 8", 5 ¼" and 3½" . Then came CD and DVD drives Iv'e noticed that a lot of modern cases do not have a bay for CD/DVD.
We used to make our own floppy and HDD cables. It was way neater and less origami required when you had exact lengths. It was pretty easy. In the end probably easier than dealing with all the mess of the ribbons over life of the system.
Yep, because the CS jumper never worked right either...or the scsi cables were so tight and twisted you were sure the connectors on the HDDs would break off.
Gr8 shirt Carey, one of my fav old school games, lots and lots of quarters 😄. I know what U mean and I remember those old ribbons, those were the days, appreciate the info 👍🏾👏🏾
I immideately liked and subscribed to the channel. What a clear explanation. Those flashbacks to IDE days brought back those memories of assembling my first PC.

On top of that, the two wires carrying such pairs of inverted signals are twisted, meaning that the mathematical area enclosed by the two wires is very close to zero, since the sign of the area of each subsequent "loop" between each twist alternates between +1 & -1,and the areas of all the "loops" are quite similar. This leaves a net area with which to pick up magnetic noise close to zero. Thus, magnetic noise is greatly reduced, too.
In such arrangements, there isn't even a separate clock line, eliminating the possibility of clock skew between the clock line itself and the single, serial signal. Instead, the clock is inferred from the data signal.
The speed potential of LVDS serial lines appeared in things like SATA and serial SCSI - serialised versions of older, parallel standards.
In the case of PCIe, each "lane" is an LVDS serial connection, albeit without the possibility of twisting pairs to reduce magnetic noise. Each lane runs at somewhat separate clock speeds, notwithstanding the fact that there's a very fine limit on how different those speeds can be. Data is sent serially down each PCIe lane at one or more bytes at a time, depending on the exact standard. Sequences of data are split and sent down multiple PCIe lanes, in the case of "x2" & greater PCIe arrangements, roughly in parallel. Within the fine limit within which signal skew can be tolerated across multiple lanes, circuitry reconstitutes the data in the right order.
So even though PCIe can have multiple lanes, it is still not a truly parallel bus. It's a roughly parallel set of serial connections, each seeking to exploit the high speed advantages of LVDS.
IDE days. Always bring tears to my eyes :)
I cry tears of soy
Sure Lock sounds gross
That og Xbox cable and Xboxhdm
I still have ye olde computer in my grandma's house xD 40gb drive with WinXP on it :')
yeah but SCSI (Scuzzy) was pretty decent back in the day. I'm old leave me alone.
Having juggled with ATA cables for the better part of my youth, I found this explanation so easy and direct, with none of the marketing jazz and distractions from the central point of the upgrade.
It helps me in 2021 to build my pc. great man
This was extremely informative. Thank you for taking the time to clear this up.
Molex Plugs, they either get stuck into a drive or fall out of a drive. You guys forget about "Micro Jumpers" and SCSI, I/O Addresses, IRQ conflicts with sound cards or com ports, and Device ID Nightmares. I do miss the old MFM and RLL "jet turbine" sound effects though.
then there was DOS
I've got a triple height 5 1/4" MFM drive (10 Mb - Wohooo!) that sounds like a jet turbine firing up!
Two words... Dip Switch
Or flipping tiny DIP switches to set multipliers for the CPU....
I would just like to say I found this video to be very informative, as this is my first time as a viewer i have definitely clicked the subscribe button. Thanks
It’s been 20+ years since I have built a computer. Now I have a teenager that wants a gaming pc. I have the foundational understanding of how to to build one but did not comprehend the new technology, until this video. I remember the days of master/slave and SCSI drives. Thank you for this video
I'm trying to build my first computer and thoroughly trying to research what all these acronyms and numbers mean and what they actually mean in layman's terms. This video helped a lot. Thank you for the great explanation and background information!
Your detailed computer build videos and tips helped me a lot while building my own PC. Thanks for the sincerity and effort you put in making those incredibly instructional videos.
Thanks for this explanation. It is so simple even a three-year-old kid would understand. Exactly how it should be explained without unnecessarily complicating things.
I never wrote comentts, But sir, you teach me something amazing, thanks a lot! I now love your cjannel!
Hello from Brazil! I've been watching tons of vídeos to check these differences explaned and you were the only one who was able to explain it in a way I could understand. Thanks!
I always remember using those IDE cables that has to reach the master drive, slave drive and still reach the MoBo.. and many times it was a tight fit without a centimeter to spare.
Thank you so much for posting this video! I'm one of those "old schooled" who started putting rigs together since the 1990's (early 1990's) and I know about the PATA vs. SATA cabling nightmares, etc. There are a lot of videos out there that attempt to clarify the M.2 vs. NVMe confusion but after watching them, it leaves even more confused. This video was very well made, with great and quick intro explanation as to the development of the different technologies and the actual visuals with sizes and installations--and compatibility issues, including the very important BIOS setup! Thanks again, and keep up the good work!
GREAT video!! I've watched ~4 videos and read SEVERAL articles on this, as I am completely new to this... yours instantly made it click! Going back to the roots was the PERFECT way to explain it, thanks man!
I have no doubt that you are an educated person. I love it when I listen to someone knowledgeable and he knows what he talking about. I really appreciate this lovely video. Thanks
Best explanation I ever heard. In 50 years, I never unnderstood it as you just explained. Thank you. You understand, you work it, and you teach it, 🌟 🌟 🌟 .
Most excellent clarification. I was getting mad trying to insert a 2019 NMVe card to an Alienware that apparently only takes M.2 (SATA) cards with two notches.
P.S. Nice time capsule with the Origami PATA cables of old. And yes, they did messed-up airflow in a gaming rig.
Would a stick of gum be a type of bubble memory?
you'd lose all the data when the bubble pops...
The user could just memorize it. It's only one bit.
I actually hope someone familiar with computer memory and bubble gum formulae stumbles in here. Maybe they can explain how to store more than one bit per bubble which would be eight sticks/chewers per byte.
The stick of gum uses Quantum Bubbles. :P
It has long-lasting memory.
I remember watching you back in 2015 when I first built my PC, thank you.
Best explanation I had seen on youtube. And I am including all those made in this 5 years gap since this video was made. I wanted to leave a comment and I am hoping that you still make videos like this. Now I have to go to suscribe... cheers!
Holy Cow, this is an incredibly great video. I have found this M.2 vs NVME very confusing, but you have done a brilliantly clear job of explaining it. I used to build computers with PATA, etc. but lately only buy used HP Z workstation for myself and my clients. Getting older ones without mboard M.2 NVME sockets equipped with an adapter so they boot the OS can be a headache because of adapter compatibility. As for gaming, I used to setup DOOM Novell networked for 3 computers on my home office, I wonder if that's what you were referring to. PS I like your gas range and exhaust system too! Thanks a lot.
I'll take the gum 😏
HENRY THE RC CAR lmao 😂
I mean it is the lowest cost
@@gerald8573 I mean, yeah, and you could probably carve a few characters onto it with a toothpick, or something. So it's not like it can't store ANY information.
I thaught it was a green m3 sticky thing
Ayo
Great video - I think your's is the best at explaining the differences..... Just off to make sure my BIOS isn't set in auto... Which I am 99% sure it is :(
Thank you for a clear and concise explanation of these technologies. 😀
Man, those first few minutes were unexpectedly emotional, held back a tear and all...
Hi. Great video! No you did not confuse me. I’m an old school computer guy too, so the fact that you went back to hay day of IBM and the crazy connections we had to deal with, that actually helped me. Now I know what I’m buying when it comes to PCiE in the realm of storage. Thanks.
"I'm the OG, i'm the Original Gamer"
really well explained, didnt even get lost, awesome vid
excellent video now i understand the m.2 and NVMe differences -- thanks this made a subscriber
Thank you... Very big help. The pictures and diagram help 100%. Your video is simple to understand and straight to the point. Excellent!!!
This is by far one of the best videos I have watched. Very well explained. I built a few computers and didn't even know there was a difference till today. Thank you
This was seriously so much informative. Thank you 🙏
thank you for your video, super informative and very well explained. I'm looking forward to more of your videos.
32gigabits is the current nvme limit which cant be saturated by a single drive atm, it takes around 2 to 3 high performance drives to saturate it
3-drive Raid 0 NVMe.... Mmmmmmmmm...
I'm running 2x 970 Pro on RAID 0 on an Asus Z370-i.... love it... Don't think I will ever use SATA SSD or spinning drives on anything but backup/archives/NAS again.
4 years in but this is still informative AF. Thanks man!
I remember going from IDE HD to a lower level SATA it was impressive. Than the lower level SATA HD to a SATA 3 SSD even more impressed. Than from the SATA 3 SSD to a M.2 NVME and was blown away. It still amazes me and I upgraded ~Sept 2019. Some game times went from 3-5 minutes down to ~20 seconds.
Excellent, I saved this video for reference. Btw I was a Galaga champ in my town with 7.5 million score, thanks.

Damn! He's such a very well spoken person. I wish I was like that 😪
Ya I was thinking that too, natural speaker!
Me too!
Experience Speaks Bro😅😂😁
Thank you so much!! I have been searching for hours trying to understand the difference. You explained this so clearly!
Very good and clear explanation of the various formats. I used to work as a repair technician and can remember floppy drives 8", 5 ¼" and 3½" . Then came CD and DVD drives Iv'e noticed that a lot of modern cases do not have a bay for CD/DVD.
We used to make our own floppy and HDD cables. It was way neater and less origami required when you had exact lengths.
It was pretty easy. In the end probably easier than dealing with all the mess of the ribbons over life of the system.
Oh god the nightmare of scsi and ide was real.
Stephen Huxtable yip, youngsters just don't get it. W/UW/U2W/U3W... never mind wonky terminators or mixed up jumper IDs :)
LoL! You know it!... :)
Yep, because the CS jumper never worked right either...or the scsi cables were so tight and twisted you were sure the connectors on the HDDs would break off.
Don't forget to terminate your scsi cables.
lol oh the memories, ohhhh the memories!
I started in I.T. about 16 years ago. I remember the old IDE standard. I didn't even attempt cable management back then.
Optane! I worked on developing that stuff as a dry etch engineer at Micron 5 or 6 years ago. It's cool seeing someone actually talk about it...
Easy to understand with slight sense of humor. I'm subscribing after seeing this. Keep up the good videos.
Gr8 shirt Carey, one of my fav old school games, lots and lots of quarters 😄. I know what U mean and I remember those old ribbons, those were the days, appreciate the info 👍🏾👏🏾
Great video. That was an easy to follow explanation. Thank you for this straight to the point lesson.
Very useful piece of info. Thank you very much 👍🏻
It has been 14 years since my last build. Thank you for explaining the newer technology of storage.
What a lovely cruise down memory lane in the beginning. Amazing video. Great explanation. Thank you so much. 🙏
Nice video, clearly explained and comprehensive. Thanks!
2x Samsung 950 Pro's in raid 0. I'm impatient, and it was worth every penny.
When you said I'm the Orignial OG I immediately thought OMG this is the Architecht from TRON :)
Henri Allou bahahahaha
I immideately liked and subscribed to the channel. What a clear explanation. Those flashbacks to IDE days brought back those memories of assembling my first PC.
Finally an expert who can put over technical info - thanks very much.
"I'm the OG" , 🤣🤣 . Love it!
