    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.

      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.

      @@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.

    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!

      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.

    Interesting overview. To add to that a bit of experience from a Windows sufferer.
    Biggest threat to SSD lifetime that causes lots of P/E cycles are Windows' dependency on its page file, and many apps that rely on temporary files to register some state information as surrogate global variables.
    Biggest threat in Windows to stability is "fast reboot" that is on the critical path of sound updates. So I switched that off and now my page file needs to be created every day. I have tried to run Windows without page file and theoretically this should be possible - in practice you can only run Windows, use its control panels, and run simple apps like Notepad.
    Biggest threat to I/O performance, including NVMe, is the South Bridge chip on the motherboard where most I/O devices are in competition for CPU to access them.
    To defeat some or all of these problems, I bought a PCIe add-in card that facilitates a Windows RAID 0 and gives direct access from the CPU's I/O lane to the card. With 4 lower capacity SSD that have a relatively large cache, I now get higher I/O speeds on that, than I could ever get from an NVMe on the South Bridge. And note here that even the NVMe connectors on the motherboard listed as PCIe are generally on the South Bridge.
    Now I keep my I/Os distributed across separate I/O lanes and the cheaper SSD RAID 0 array does not contain data I need to backup, ever. Or it is backed up by the application after each session like the Lightroom catalogues.
    I have seen the P/E cycles (TBW) and in product name terms Samsung EVO would have been good enough, but I still bought into the PRO version. Here I run RAID 1 with 3 arrays to keep e.g. OS and user data separate. Really important data is stored in my NAS on RAID 5 which replicates all updates to a second NAS which replicates to an offsite NAS.

      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.
