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..
Plextor's DRAM buffer aids in keeping latency low for both reads and writes. Here we see a steady .1ms average read latency.
The write latency can spike when the M5 Pro's aggressive garbage collection kicks in. After the GC run is over the write latency goes back to very low levels.
