Do those SSD's have capacitors (aka power loss protection)? I took a
look at the spec sheet on samsung's site and I don't see it mentioned.
If that's the case it could certainly explain the performance you're
seeing. Not all enterprise SSD's have it and it's a must have for Ceph
since it syncs every write directly to disk.

You may also want to look for something with a higher DWPD so you can
get more life out of them.
