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.

The X25-M leads the field with iPEAK workloads that include a read-intensive Virtualdub import operation as a secondary task. Otherwise, the drive's performance is mixed, and not nearly as consistent as that of the Samsung FlashSSD.

If we average all our iPEAK scores, the FlashSSD comes out ahead of the field with a mean service time of 0.81 milliseconds. The X25-M scores a second place finish with a mean service time average of 1.05 milliseconds—0.26 milliseconds ahead of the VelociRaptor, which isn't bad at all.
