AIDA64 offers 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 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 and Toshiba.
Last week we looked at a drive with a lot more variation in the read access time test and we were starting to worry if the latest SandForce firmware was the cause. Luckily today we can say that it wasn't a firmware issue.
The Chronos Deluxe held the minimum .21ms read access time throughout the test other than a tiny blip on the graph. Access time is the area where you feel an improvement when coming from a mechanical drive, but it's often overshadowed by the large transfer rate numbers put on the board by SSDs.
The write latency held steady as well with an average of .22ms.
