Question SSD at 81% after 4.5k hours of use

[grubesa]

I have a "KINGSTON SA400S37480G 480, 1 GB" SSD that I've installed in a PC 15 months ago. CrystalDiskInfo says it has been on for 4472 hours, has total NAND writes of 45989 GB, 29837 GB of host writes and 94711 GB of total host reads. The health status says it is 81% good, and is currently running on 30 degrees celzius. When would the SSD approximately stop working?

hard to tell, they can last a very long time. it will probably wear out eventually once it meets all its maximum writes.. it could last for years

that's a decent amount of reads/writes for 15 months; you have twice the reads of my 960 EVO and 80% of the writes, but with mine being 5 years old...

I'd suspect their '81% health' algorithm is just being conservative, it's not as if the SSD stops working at x-percent or TBW/writes...like some Intel SSDs were darn well known for doing...

"XX% Health" is NOT a straight line determinant of when you should think about replacing it, or how long it might last.

You need to be prepared for full replacement at all times.

I've had a SSD go from "99%" to absolutely dead pretty much instantly.
