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.
We've wrote about IMFT 20nm flash and the latency issues a handful of times before. The MyDigitalSSD SMART is a rebadged ADATA SX300 with 25nm IMFT flash. With that in mind, the new 20nm version nearly quadruples average read latency.
The write latency also increased with 20nm flash over 25nm.
