According to the specs for database storage:

"Random 4KB arites: Up to 600 IOPS"

Is that for real? 600 IOPS is *atrociously terrible* for an SSD. Not much faster than mechanical disks.

Has anyone done any performance benchmark of 320 used as a DB storage? Is it really that slow?

Apologies if this has already been posted here (I hadn't seen it before today, and
can't find a previous post).
This will be of interest to anyone looking at using SSDs for database storage :
