I'm looking for generic advice on hardware to use for "mid-sized" postgresql servers, $5k or a bit more.
There are several good documents from the 9.0 era, but hardware has moved on since then, particularly with changes in SSD pricing.
Has anyone seen a more recent discussion of what someone might want for PostreSQL in 2017?
The rules haven't changed much, more cores (even if a bit slower) is
better than less, as much ram as the budget will allow and:
SSD
But make sure you get datacenter/enterprise SSDs. Consider that even a
slow datacenter/enterprise SSD can do 500MB/s random write and read just
as fast if not faster. That means for most installations, a RAID1 is
more than enough.
