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.
RAID didn't start with SSDs. My first array was with two Maxtor 20GB PATA drives... a few years ago. The difference between the spinners in RAID and SSDs is latency.
The mechanical drives would increase latency in an array, but SSD latency in an array is nearly identical to that of a single SSD.
Since SSDs don't increase latency in RAID 0, you get the best of both worlds, great access times and increased sequential performance. Vector does well with both read and write latency.
