HDTach 3.0.4.0

HDTach v3.0.4.0 


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.

HDTune, like some of the other benches used in this test, *really* did not like the HighPoint HBA. This can be seen below:

The HBA threw some serious curveballs at HDTach.

For comparison, here’s a quick HDTach run of the same drive in an external USB3 enclosure (thus bypassing the HBA):
