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 Crucial RealSSD C300 has higher latency than most SSDs, but the HighPoint RocketRAID 2760 is able to keep that in check when using RAID settings. Even though the HPT controller doesn't have onboard cache, the latency is lower than we found on both the LSI and Adaptec controllers. The Adaptec actually ran into some issues where latency would spike, like we see when using JMicron controlled SSDs.

When it comes to write access times, the HPT RocketRAID once again was able to keep the latency lower than what we found on a single drive. The other controllers cache did come into play here and we see both the LSI and Adaptec taking advantage of their 512MB cache.
