Your results are consistent with the benchmarks I've seen. Intel SSD have much
worse write performance compared to SSD that uses Sandforce controllers, which
Vertex 2 Pro does.
According to this benchmark, at high queue depth the random write performance
of Sandforce is more than 5 times that o

So the Intel 710 kind of sucks latency wise. Is it because it is also
heavily reading, and maybe WAL should not be put on it?
A couple quick thoughts:
1. There are a lot of moving parts in the system besides the SSDs.
It will take some detailed analysis to determine the cause for the
