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.

LSI SandForce based drives used to have a little higher latency than other SSDs, but decreases in flash geometry and increased capacity per die hasn't helped latency. The LSI SandForce drives have stayed about the same when it comes to latency, but the other drives have caught up.

The latency issues with drives using new 20nm IMFT flash and 19nm Samsung TLC flash really shows itself when measuring write latency. The PNY Prevail 240GB keeps the latency steady across the test.
