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 new Toshiba Toggle Mode flash has been putting up some very impressive latency numbers. Here we see the M3 Pro delivering an amazing .07ms read latency performance. This comes very close to the OCZ Octane's .06ms that we recorded a few months ago, the lowest we've seen to date.
Access time and especially read access time is what makes your Windows, applications and general computing experience feel much faster when using SSDs. Most of the manufactures like to talk about their large read and write sequential performance because big numbers are more marketable than small ones. It is these small numbers though that you can really feel while using your system.
The write access times on the Plextor M3 Pro 128GB are the lowest we've recorded to date on a computer, non-PCIe drive. I don't think it is electrically possible to get any lower with SATA.
