> It's as serious as in to read data consume the disk, and the faster its read the faster is consumed

Numbers, please. Quantify that or GTFO. You keep quoting stuff that implies SSDs are horrifically unreliable and burning through their write endurance alarmingly fast. But the reality is that even consumer PCs with cheap SSDs are not experiencing an epidemic of premature SSD failures.

EDIT:

> You should have noticed that SSD disks no longer come with a 10-year warranty.

10-year warranties were never common for SSDs. There was a brief span of time where the flagship consumer SSDs from Samsung and SanDisk had 10-year warranties because they were trying to one-up each other and couldn't improve performance any further because they had saturated what SATA was capable of. The fact that those 10-year warranties existed for a while and then went away says nothing about trends in the true reliability of the storage. SSD warranties and write endurance ratings are dictated primarily by marketing requirements.

    "So, on page 8's graphs, they show that 800GB-3800GB 3D-TLC SSDs had a very low "total drive failure" rate. But as soon as you got to 8000GB and 15000GB, the drives had a MASSIVE increase in risk that the entire drive has hardware errors and dies, becomes non-responsive, etc."

  • Would you care to explain how any of that supports the points you're actually making here?

    Some of what you're spamming seems to directly undermine your claims, eg.:

    > Another finding is that SLC (single level cell), the most costly drives, are NOT more reliable than MLC drives. And while the newest high density 3D-TLC (triple level cell) drives have the highest overall replacement rate, the difference is likely not caused by the 3D-TLC technology

    • "likely" not caused by. Any case I delete such spamming? link.

      Other day, if you don't mind.
