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 cached fills. This usually happens only with controllers manufactured by JMicron and Toshiba.
We spend so much time looking at SSDs like HDDs and focusing on the data transfer performance when the biggest performance gains come from the access times. This is how long it takes the drive to respond to your request for data. This is also what makes your new SSD 'feel' fast with instant response.
In the read test we see the RunCore Pro V 2.5" SATA III delivering on average response that takes a quarter of a millisecond. I had a bit of a laugh while writing that because it is so fast we might as well call it instant. I wish my coffee came out that quick!
The write access time was measured almost as fast. At the bottom of the charts you can see the Western Digital VelociRaptor, one of the fastest consumer platter drives ever built in relation to access time. As you can see, the Pro V is much, much quicker.
