This particular tutorial is excellent, and has expanded this old dog’s understanding of non-rotating storage devices. I was vaguely aware of the cycle-based limits on lifespan, and now I see the details far more clearly. Thank you..

Probably the missing part is to talk about how HDD also has a controller (many people don't realize how everything abstracted) and that both SSD and USB-flash drive sticks are both flash-based and basically the same thing. The differences are in the number of chips, etc. and how fast & smart the controllers are.

I have a good quality system nvme drive and a decent larger drive for game storage. I do a little bit of video editing but nothing that requires massive reads/writes. I might see if any good deals pop up before Christmas as drives like the Kingston Fury and Western Digital 850X have been a nice price in recent months. As Samsung recently brought out their 990 Pro drive the 980 Pro has also seen discounts. These cost so much until fairly recently so it's nice to see prices come down. Long may it last! 😁

Thanks for more very useful info Chris. It seems that as a rule of thumb in consumer SSDs the TBW figure is roughly half the numerical size of the drive and given should give many years of normal use before failure. Most SSDs also have 3 to 5 year warranties. But as a professional I have seen SSDs fail without warning long before reaching anywhere near their advertised TBW or warranty period. And once they do (unlike with magnetic drives) you can more or less forget about recovering any data from them. Admittedly in the same breath I had a WD 4Tb magnetic drive catastrophically fail two days after buying and partitioning it, and it was completely unrecoverable. So I guess having a good backup strategy is increasingly important these days.

Thanks for making sure TBW was in there. It's good to note that TBW is often used to limit warranty (like "1200TBW or 3-years, whichever comes first") but that DOESN'T mean a drive dies when it exceeds rated TBW. It does mean it's less reliable at storing data long-term + power-off. But I have SSDs at 3x their TBW still working with no errors.
