Hd Tach 3: 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.
Same story, different board when it comes to our HDTach Average Read scores. Both boards score right with the pack.
Burst speeds are good on both the XFX 650i Ultra and the 680i LT boards. They score near the top here, though you would be hard-pressed to notice any difference in any of the boards in real use.
