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.
Let's start with the GIGABYTE RAID 0 tests with two Barracuda XT's. Our tests show a 30 MB/s increase at the maximum transfer speed over a single Barracuda XT and close to 55 MB/s on average. We were hoping to see higher numbers, closer to 2x the transfer speeds, but we didn't get there.
In the single drive tests we see everything performing at nearly identical speeds no matter what controller or drive combination was used.
The write tests were quite a bit different for GIGABYTE's RAID 0. Here we see no benefit at all by using two Barracuda XT's in RAID 0 at the maximum speed, but the chart filled in the average and minimum speeds quite nicely.
The single disk write tests were all right together and within the margin of error.
