> My intuition on this may be wrong, but it seems to me that the lack of variable seek time ought to lessen the variability in I/O performance that one hears so much about.
Take this with a grain of salt, as I'm limited in my experience, but I believe that's not entirely the case. Modern SAN controllers are optimized for very consistent latency on spinning platter disks, even under heavy load. The big benefit that I see in SSD-backed SANs is increased I/O bandwidth.
