While single-thread random performance is only in the middle of our test group, we see very nice performance at multi-threaded reads.

If that seem incremental, going on insignificant, bear in mind that numbers above 500MB/s for peak throughput are hammering up against the maximum capabilities of the SATA6Gbps interface.
