Why does an SSD fail?

Question

Solid State Drives

A small server is running on Win Server 2012r2, several HDDs are combined into one hybrid pool (non-critical folders without duplication, critical ones are duplicated) using StableBit DrivePool. And then one day I decided to add the KINGSTON SV300S37A60G SSD as a cache drive to speed up work with small files.
And then the problems began. After some time (usually about a week), the SSD drive falls off, it is not treated by a normal reboot, only by a physical blackout. Changed the firmware - does not help. Changed cables - did not help.
There is a suspicion of a non-working TRIM, tk. the trimcheck utility does not show that TRIM is working, although CrystalDiskInfo shows that the disk supports it.
Disk defective? Throw it in a laptop and take another? If the other, then what is the best price-quality?
Or is there some other way out?

Answer 1

Why does an SSD fail?

The reasons may be different.
To begin with, it would be nice to decide what it means to "fall off"? Disappears from disk manager? Or just the cache stops working?

There is a suspicion of a non-working TRIM, tk. the trimcheck utility does not show that TRIM is working, although CrystalDiskInfo shows that the disk supports it.

Lack of TRIM will simply reduce the write speed and nothing more.
I doubt that a slow write will cause the disc to fall off - although I repeat, it's not entirely clear what it means to fall off.
Regarding the work of TRIM - CrystalDiskInfo reports that the disk understands such a command.
This does not mean that someone sends this command to him, and even if someone sends this command, it is not a fact that it reaches the disk.
Reid and StorageSpace don't usually let her through.
You can work great without trim - leave a lot of reserve, and that's it.

Disk defective?

Maybe. Electronics is a complex thing, and has the ability to break down, even if new. It doesn't matter if it's HDD, SSD, or graphics card.

Answer 2

The disk is most likely normal, I have the same kingston v300 480 GB, in software RAID0 the centos 6 system, but I randomly fall off every 3-4 days 1 disk out of 4, I don’t even know what to do. The warranty is still a year left, but I think they will say that everything is in order.
