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 SLC flash does offer much lower access times when compared to the same controller used with MLC flash. The Marvell based drives use DRAM buffers, but the SuperSSpeed S301 SLC delivers equal read latency without a DRAM buffer.
The SLC write latency is also much lower than the MLC LSI SandForce drives. This should lead to higher IOPS performance at lower queue depths.
