They last for years with constant writes; on the order of magnitude with petabytes The properties surely vary among drives... but this isn't worth much concern

They last for years with constant writes; on the order of magnitude with petabytes The properties surely vary among drives... but this isn't worth much concern I'd throw a computer swapping this much out the window before the NAND would give up

A typical Samsung SSD is warrantied for between 100 and 500 TBW[1]. [1] https://semiconductor.samsung.com/us/consumer-storage/internal-ssd/870evo/ https://semiconductor.samsung.com/us/consumer-storage/intern...

  What are you trying to say here, that one can only expect what's warrantied? I expect nothing more than OEM support in that warranty... and that things generally continue to work outside of it. Techreport (and others, before we go down that path too) tested those along with many other drives. They were written to for more than a year and a half continuously. Sure, Samsung and others only agree to financially be on the hook for N bytes. The point is, the drive can handle it - and the situation doesn't make sense. Let's take a step back or two. We're focusing on numbers one would never even have the patience to reach while swapping

    Used drives can have life in another device or the whole device may be reused for a less taxing purpose ... if it hasn't been exhausted because of cost cutting.

      Sure, so hopefully the person before you bought a machine with sufficient memory ... and didn't walk away from it for days, if not weeks, while it was swapping. Ignore the numbers. The proposed problem is ridiculous.

> They last for years with constant writes; on the order of magnitude with petabytes For anyone else wondering, that test did use one TLC disc (Samsung 840). It had a major issue at 300TB, then went on till 800 (failed somewhere around 900). Not many new MLC/SLC in the consumer market. https://techreport.com/review/the-ssd-endurance-experiment-theyre-all-dead/ https://techreport.com/review/the-ssd-endurance-experiment-t... Unless you meant another test?

  That's indeed the test I had at the forefront. That's a good/fair distinction - QLC or whatever now is probably less reliable. My point remains, though. Worrying about the lifetime of the drive by way of memory/swapping is silly. You'd have to leave the box unusable for days, if not weeks, to meaningfully contribute to wear.
