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 one area I'm surprised about is the latency. PCIe is a direct shot to the CPU, so I expected to see a latency drop, but that didn't happen. I went back and tested the A110 on several motherboards going back to X58 and the latency was consistent, even with a PCIe switch in the path.
The write latency was a little higher than I expected. The other drives on the chart were tested with Intel's driver so we'll have to wait and see what comes up later with an optimized driver.
