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 new spare area, 256GB down to 240GB user capacity helps reduce latency. The MDSSD BP4 scores a solid .04ms in our read access test. This is a little higher than want we recorded with the 240GB version, but it's still very low.
Phison, the controller maker responsible for the S8, still has a bit of an issue with write latency. The large spike in the write latency test came at the same point where the spike occurred in the sequential read after heavy random write test.
