SMART diagnostics work perfectly, but you need a tool that can evaluate
them reliably, and smartctl usually can't do that. You also need
software with which you can update the firmware of the SSDs. When Linux
was still supported for most of my SSDs, I regularly installed firmware
updates.

Maybe I can do something with smartctl for my two NVMe SSDs, but for the
5 SATA SSDs I get nothing that is particularly helpful. While my oldest
SSDs are in another PC, I still suspect that the Power_On_Hours are not
necessarily correct. I might be mistaken, but I guess that some are
running for longer. For the NVMes I don't trust the Data Units Read,
Data Units Written, Host Read Commands and Host Write Commands. Through
regular backups of large amounts of data I have good reason to doubt at
least the amount of read data. I might be mistaken here, too.

The KIOXIA software provides a health status. I wonder if Available
Spare - Available Spare Threshold - Percentage Used (obviously from the
spare not from the actual capacity) = percentage of remaining health?
