My wife's stock M.2 SSD died (I forget the vendor, it was some South Korean brand I had never heard of) in her 2 year old Dell XPS 13. There were no warning signs, just one day it wouldn't turn on.

I searched everywhere but couldn't find a service that could recover the data. I'm guessing the microcontroller got bricked somehow. In that situation the only method of recovering data seems to be desoldering the flash chips and resoldering to a board with a working microcontroller (I'd love to be proven wrong here).

At any rate, I replaced it with a Western Digital M.2 SSD and it's been working fine since.

But, that whole episode shattered my notion that SSDs were more reliable than HDDs because of the fact that they have no moving parts.

From my experience SSDs die hard and you will get nothing back from them. I always thought they may go into read only mode but I have never seen that.

Restore form backups. Chances are if you're at the point where you're trying to do data recovery you're already hosed.

Apple had a backup solution that was easy to use.
