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 cache fills. This usually happens only with controllers manufactured by Jmicron.
The read latency was steady in our AIDA64 test. We recorded .09ms, around the same as the other Extreme II capacity sizes.
In the AIDA64 write latency test we were able to see where the DRAM and SLC tiering crosses over. On the chart it shows up as erratic write latency, but in the benchmark, it shows as scaled planes.
