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.
The Z5K320 was able to beat the WD Scorpio Blue in the average read access test and is very close to the performance of the 7,200 RPM drives.
The Western Digital Scorpio Blue had an issue with the write access test most likely due to its advanced format configuration. With the WD data not available we turn to the other drives and this is where things start to get interesting. Hitachi's Z5K320 actually scored better than the 7K500, a 7,200 RPM drive.
