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.





Starting with a new drive, the first few tests allow us to get the drive out of fresh out of box (FOB) performance and into a consumer steady state. Reading across the drive we hit a maximum of 443MB/s and averaged 421MB/s. This level of performance is pretty standard on SandForce drives with firmware based on 5.0.3 and 5.0.4.




Write performance is slower on SandForce drives with 512GB of NAND flash. Here we hit just over 400MB/s average, but there is nothing slow about that.
