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.




The A-DATA S501 is running with a little more read latency than the C300 128GB, but the S501 is still hanging in there with the SandForce SF-1200 drives.




The Marvell controller in the Crucial RealSSD C300 had some of the highest write latency speeds we have tested outside of the JMicron stuff. It looks like that is no longer an issue with the new Marvell controller.


That's it for the synthetics. We will head to the hall to get the CDM 4K numbers in the morning.
