AIDA64 offers several different benchmarks for testing and optimizing your system, or network. The Random Access test is one of very few (if not the only), that will measure hard drives random access times in hundredths of milliseconds, as oppose to tens of milliseconds.
If a drives has only one or two tests displayed in the write test, it means 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.
Latency is the one area where I expected to see performance increases, but after testing both Intel PCIe, and AMD PCIe, it looks like we won't see a major latency decrease. We'll have to see what happens when m.2 SSDs move to PCIe 3.0 with 128/130b encoding.
