iPEAK multitasking
We've developed a series of disk-intensive multitasking tests to highlight the impact of seek times and command queuing on hard drive performance. You can get the low-down on these iPEAK-based tests here. The mean service time of each drive is reported in milliseconds, with lower values representing better performance.

In our first wave of iPEAK multitasking tests, the VelociRaptor only manages the quickest mean service times for two workloads. The VR150 remains competitive with the other three, where it always lies within striking distance of the top spot, but there's no domination here—well, not unless you compare the VelociRaptor's performance with that of its predecessors, which are much slower with each workload.
