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 and Toshiba.
The SanDisk Ultra Plus doesn't sacrifice latency for sequential performance, here we see the read latency for a set of drives and the Ultra Plus 256GB manages to stay competitive.
The write latency is higher than what we like to see coming from a Marvell based drive with a DRAM buffer.
