HDTach 3.0.4.0
HD Tach will test the sequential read, random access and interface burst speeds of your attached storage device (hard drive, flash drive, removable drive, etc). All drive technologies such as SCSI, IDE/ATA, 1394, USB, SATA and RAID are supported. Test results from HD Tach can be used to confirm manufacturer specs, analyze your system for proper performance, and compare your performance with others. HD Tach is very easy to use, quick, and presents data in easy to read graphs, including the ability to compare two storage devices on screen at the same time for easy analysis.
In our Burst Speed test the Raptor X and its 150 GB/s controller really shows the weaknesses of the old drives and the VelociRaptor is able to push past the 750GB Caviar drive by a noticeable margin. The average read/write speeds of the VelociRaptor are also just impressive as well and easily beat out both of other hard drives in our test today. How? Well take a look at the random access times the drive is pulling in: 6.9ms – 17% faster than the Raptor X and 98% faster than the Caviar drive.
