Everest Random Access Time
Everest Ultimate and Corporate Edition offer several different benchmarks for testing and optimizing your system or network. The Random Access test is one of very few if not only that will measure hard drives random access times in hundredths of milliseconds as oppose to tens of milliseconds.
Drives with only one or two tests displayed in write the write test mean that they have failed the test and their Maximum and possibly their Average Scores were very high after the cached fills. This usually happens only with controllers manufactured by JMicron.
All of the data given to us and even the spec sheet suggest that the new VR200M should have lower read access times, but the Marvell SATA 6G controllers adds latency that we wouldn't see if the drive were tested on an Intel SATA controller. Still, Marvell owns the consumer SATA 6G market right now and we have to work with the hand we are dealt.
The same is true with the write latency. In this test, though, the VR200M is able to give better results than we see from the VR150M, but if both were tested on the same controller the SATA 6G VelociRaptor would give us even better results.
