Hello, my SSD health is showing 80%. Used for almost 2 years.
SSD model is Toshiba TS256GMTE220S 256.0 GB. Checked with Crystal Disk info and hwinfo64.
Is this bad?
No this is not bad at all. It is a relatively small drive, which do wear out faster because they tend to be fuller and so there are fewer cells to spread the wear amongst. To slow down wear, don't keep unnecessary files.
Another way to look at it is to consider that it is a $30 component (at current prices). If it lasts 10 years, that's a cost of $3 per year. Surely that is acceptable?
If it really concerns you, then when it gets down to 20% health (predicted to be 6 years from now), replace it with a new one (by that time, a much bigger drive).
