HD Tune 3.50 Pro measures disk performance to make comparisons between drives or disk controllers. In the 3.50 Pro version, the user can measure not only drive performace as a whole, but there is a more precise file benchmark and random access benchmark as well.
Random Access Benchmark:
For the File Transfer test, I will take a file straight off my hard drive that is 2GB in size containing various file types and transfer it from a source hard drive to each hard drive and time how long the transfer takes. Time will be in seconds, with a lower time being better.
In the read benchmark, the Barracuda XT is the highest performing drive in three out of the four categories - the Raptor sees a lower access time due to the 10,000 RPM spindle speed. In the File Transfer test, the Barracuda XT carries a slight advantage over the 1.5 TB drive on the 6Gb/s controller, but when the 2TB drive is used on the SATA 3Gb/s controller it takes 3 seconds longer to move the data.
