I can see a lot of room for improvement in the random reads, but I'm quite impressed with those max throughput numbers. I believe that adding the SSD cache should greatly improve the random reads.
Any idea why my random tests are so low? It seems a bit lopsided to have reads that fast and random crawls at 1100 IO/s
