I've measured the performance of this drive from a couple of directions now, and it always comes out the same. For PostgreSQL, reading or writing 8K blocks, I'm seeing completely random workloads hit a worst-case of 20MB/s; that's just over 2500 IOPS. It's quite possible that number can go lower under pressure of things like internal drive garbage collection however, which I believe is going into the 600 IOPS figure. I haven't tried to force that yet--drive is too useful to me to try and burn it out doing tests like that at the moment.
I hope someone from Intel is reading -- it would be well worth their while to just send you a few drives, since you are set up to perform the right test, and can provide impartial results.
