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.
Access time is very important when it comes to your RAID arrays. With mechanical drives the latency tends to increase as you add more drives to the array, but with SSDs the numbers are steadier. In all three of our arrays on the ARC-1882i we recorded a read latency of just .13ms.
The write latencies increased on the Areca as the complexity of the RAID increased. Still, the latency was very low and lower than the LSI.
