HD Tune Pro gives us accurate read, write and access time results and for the last couple of years has been gaining popularity amongst reviewers. It is now considered a must have application for storage device testing.
In HD Tune we get to see the performance across the drive. The single drive is able to deliver a maximum speed of around 118MB/s, but that dips to 55MB/s at the slowest point on the platters, leaving a 93MB/s average transfer speed. The RAIDed trio does much better; here we see RAID 5 averages 215MB/s and RAID 0 goes up to 268.3MB/s.
The write performance is nearly identical to the read performance. Here we see the single drive averaging 92.4MB/s and increasing very well as drives are added to an array.
