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 LSI MegaRAID 9280-24i4e was able to keep the read access times very low. The onboard 512MB of cache aided in giving us lower access times than we are able to get with a single C300 on an Intel ICH. Access time is what gives SSDs their advantage over platter drives.
I was very surprised to see the very low write access time delivered by the RAID 0 array; it was half that of the RAID 5 array. The RAID 5 write access time was still very low.
