SATA III SSD Comparison time!

Um....so what's everyone's take on the Vertex 3 Max IOPS vs. the Intel 510?

75,000 IOPS write sounds pretty nuts to me, and the Vertex 3 seems to be kicking the 510's butt in terms of seq. write.

The 75,000 IOPS (around 292MB/s) is only on highly compressible 4k write speeds at high queue depths, though really I haven't seen any really break 70k IOPS (around 269MB/s) in that regard. For incompressible/random 4k write speeds at high queue depths they're down to 32k IOPS (125MB/s).

Still better than the 510s though, which don't do 4k randoms well (slower than a X25-M). For sequential write speed Vertex 3s are anywhere from 160MB/s for incompressible to 450MB/s for compressible. Intel 510s sequential write speed stays steady at 315MB/s for either.

Long term performance degradation wise, the 510 has a Marvell controller (like the C300) and Intel firmware, so it should hold up well as both Intels and C300s do. I have no idea how a Vertex 3 will hold up yet. The newer SandForce controllers seem to have made a great many improvements over the older ones, so I doubt their performance will so catastrophically flatfline like the older SandForces, but... they're still SandForce drives, so good luck with that, I suppose.

They both look pretty yuck to me, I'd rather get a Crucible C300, Crucible M4, or RAID multiple smaller Intel 320s.
