Hey all again,
As I was preparing to configure one of my servers with M.2 SSD's, it occurred to me that there is a bit of bad mojo surrounding them. This is disappointing because I am trying to use as much hardware as I already have and not buy any more unless it is necessary or can be financed by selling some of my other, unused hardware.
The SSD's in questions are these: Samsung PM953 M.2 (MZQLV960HCJH). Mine are 960 GB. It's impossible to find anything about them on Samsung's site, so perhaps even Samsung have "disowned" them..? As far as I understand, there is an issue with the way these SSD's perform write caching, so that when data is written by the OS it isn't able to be confirmed as being committed to disk until some time later. And this leads to performance degradation and increased risk of data loss in case of power loss? Have I got the basic story right?
If so, they are not really enterprise drives, and probably more suitable for a workstation or home server. No?
Thanks for any guidance!!
