Is TRIM enabled?
If not that would be my first step.

Hey All,
This isn't related to 4D per se, but our 4D server is running a
mirrored RAID with two Samsung 850 Pro drives on Mac OS 10.13.x.
Recently I wiped the RAID and upgraded to the current OS from scratch
doing a clean install of everything. Now I am seeing a fairly
noticeable performance hit with write operations. I used to be able to
duplicate a 400MB file in s few seconds, but not anymore. I am not
running the new mac file system (APFS) on the RAID.
I'm thinking the SSDs need to be reconditioned. Any one have any
recommendations? (I can also connect them to a PC to do another wipe
if necessary.)
