SSD Wear leveling count?

[DampDog]

Just a quick question. I have a Samsung 840 series. I estimate I've had installed for about 4 years. Never had even the slightest issue with it, however I ran 'Samsung Magician' last evening and noticed that the wear leveling count was 90. I thought that the wear leveling figure was a guide as to how much life there still is in the drive. If that is the case, would "90" indicate it's 90% worn? Or the other way round and only 10% worn. Total writes = 13TB

I'd rather replace before it fails rather than pick up the pieces following a failure.

Cheers

Thanks for the pointer. According to that "Drive health is Excellent" with "Estimated life-span, 8 years, 5 months" So still tons of life in as yet. Cheers

On Samsung drives the "Wear levelling count" raw data is actually reporting the average program/erase cycles of the NAND.

If it's an 840 non pro then it will be rated to about 1000 cycles, so roughly 9% worn. It's a lot left in it yet

Cheers. Either way looks like drive still looks good for some time yet..
