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.
Samsung units have always been very good at caching, and do very well here.
The lower latencies of the V4S and Vertex Turbo score higher than their cousins.
Samsung controllers don’t seem to like how HDTach performs its sequential read test, scoring lower than expected.
All Indilinx units did well on reads and writes. The Vertex Turbo did not break from the pack as much as we would have liked to see.
