Actually, modern SSDs have lower latency than 70 microseconds:

26 microseconds for OCZ Vertex 4 (reads)


No more than 20 microseconds for Corsair Neutron GTX and Vertex 4 (writes):


While that's a significant improvement over the 70ms assumption, it's still "around three orders of magnitude slower than dram and two orders of magnitude faster than spinning disks", and doesn't really change any of the conclusions you'd have drawn using the 70ms number.

OCZ compromises a lot to get high marks on AnandTech benchmarks and great Farcry 3 FPS reports on newegg.

You should be looking at companies like STEC or higher end Intel SSDs for server applications.
