Gary passes along a PSA

Gary passes along this info…

“I didn’t see this here, and your blog is usually the first place I look for “SBS” (er.. essentials now) information:

Samsung 850 EVO SSD drives do NOT get along well with Windows 2012 R2.  In an essentials server, they’ll produce 100% crashes, and in any other 2012 R2 server, they’ll produce crashes any time the write cache is turned off (which happens when a server is promoted to a DC — which happens 100% of the time for Essentials.)

Sadly, nothing about the crashes leads a person to believe that it’s the SSD drive, but it has been narrowed down by several people.

There’s quite a bit of information once you know what to search for.  Isn’t that always the case?

Here’s some links:

This guy had the problem, even though it wasn’t narrowed down:
