One of our four "big iron" (spinning disks) servers went belly up today.
(Thanks, Postgres and pgbackrest! Easy recovery.) We're planning to move to a
cloud service at the end of the year, so bad timing on this. We didn't want to
buy any more hardware, but now it looks like we have to. 
I followed the discussions about SSD drives when they were first becoming
mainstream; at that time, the Intel devices were king. Can anyone recommend
what's a good SSD configuration these days? I don't think we want to buy a new
server with spinning disks.
 
We're replacing:
  8 core (Intel)
  48GB memory
  12-drive 7200 RPM 500GB
     RAID1 (2 disks, OS and WAL log)
     RAID10 (8 disks, postgres data dir)
     2 spares
  Ubuntu 16.04
  Postgres 9.6
 
The current system peaks at about 7000 TPS from pgbench.

 
With what arguments (also initialization)?
