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!

[@VulpisFoxfire]

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..

@@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.

[@acmaras]

I started in Freshman year in high school in 1975 programming an unseen computer in our computer lab with cards and pencil marks. Between terms in tech school I got the opportunity to take a COBOL class, programming an IBM 360 with punch cards. I still have my old TRS80 computer! Today I service automated HVAC controls and computers. You, sir, help to keep me up-to-date on the technology of computers and for that I am eternally grateful. Keep up the great work! You are of great value to people like me who sometimes struggle to keep up.

[@peterslater2914]

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. My son went onto work on movies like avatar, tin tin, planet of the apes, James Bond, just to name a few. From humble beginnings to using 300 computers to perform rendering of huge images. 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.

My desktop computer has both SSD and a HDD. The main programs and the boot system are in the SSD and the rest of my files are in the other drive. The difference is huge in terms of speed. Thanks for another video. Cheers!

[@Sup_D]

I have been using HDD for 7+ years now and still on Windows 7, and was thinking of maybe buying a 2.5 SSD for boot-drive and install Windows 10 on it. But then i noticed that both my i7-4770 and Intel DH87RL Motherboard don't have any driver support for Windows 10, and since both the products have been discontinued and there is no new drivers for them, not sure what to do.

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)👌

In fact I'd argue that we should get rid of the "M" altogether and just straight to 1LC, 2LC, 3LC, .. [n]LC

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.

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.

Just bought a new 512GB NVMe to replace my 256GB one I've got now. Also bought a PCIe to NVMe adapter for my aging pc. So that's where my old NVMe drive will go to. I've also got a USB3->NVMe adapter. Very useful to test USB3 performance on SBCs. I use it to boot Linux on my PC. More than fast enough for that. I had the pleasure of working on a 32-core ARM server. All cores at 3.3Ghz. Amazing to see such performance out of an ARM CPU. I made a video about it, and wrote a review.

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.

Forget kittens THIS is the channel to watch. I've been in IT since before the PDP11 days and this channel is so much fun. Thank you

[@ExplainingComputers]

Wow, thank you!

[@dylan.t180]

Thanks once again for your fantastic videos always enjoyable and informative

SSD encryption options explained could be an idea for another video. Untangling the differences and relationships and comparisons between SED drives, ATA Passwords in BIOS, on-drive encryption vs software based.

Amazing information in a short video! M.2 SSDs were confusing me a lot and this cleared a ton of things up, thanks! Reading wikis about this has not helped as much as this wonderful video

[@ExplainingComputers]

Great to hear!

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).

Please explain also about trim, over provision and other things in ssd too

[@whatthefunction9140]

Thank-you. This cleared a lot of confusion.

Good content for many of those looking to upgrade to an SSD or upgrade their existing SSD. Thank you

13:05 I fully agree with the notation of Samsung. The industry should use this new notation.

Great video very informative yet concise

[@GaryFuller]

Another fantastic video Christopher! It's fascinating to learn new things on top of what's being covered in my degree.

SSD's also contributed to a very welcome noise and vibration reduction. The HDD spin on read and write was quite loud .

[@ExplainingComputers]

Good point -- very true.

[@chriholt]

Fascinating explanations Chris. I had no idea about the super high capacity interfaces/technologies!

[@ExplainingComputers]

Great choice of topic, and excellent coverage of the subject. Thanks.

[@deechvogt1589]

Awesome explanation video. Thanks for breaking this all down for everyone. I'm in Information Systems (Programming) and it hard to keep up on all the hardware standards. Cheers!

[@jayrowe6473]

Excellent and very informative video, which is exactly what I've come to expect from this channel. Thank you and keep up the good work!

[@ExplainingComputers]

Thanks, will do!

Nice little trip down memory lane (pun intended) for us guys that have been in IT for a very long time. I can remember working on Ferrite cores being used as storage in 1975 but was please as punch to fit a 1Tb M2 drive in my PC rebuild this year. Wonder what your 2030 version of this video will tell us?
