The QD of a real workload would depend on the device it is being ran on. If Anand ran it on an HDD first, it would sort of make sense. HDD can't keep up = QD rises. If he ran it on an SSD then QD would probably be 1ish. I surely hope QD7 is not being forced onto the SSDs by his benchmark, as that would make it useless.
Actually, Iodrive helps a bit with loading times. 1s decrease taking me from 7.5sec to 6.5sec in l4d. 4x X25-E in R0 is exactly the same 7.5s as a single X25-M though. Indilinx is slower at about 8s.
