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.

Speeds comparing the new retail drives and the original drive show very little difference in performance and thus any drives you buy will be up to snuff.  But take a look at those RAID-0 results: over 420 MB/s burst speed and 194 MB/s in sustained read speeds!  The random access time just moves down slightly – from 7.1 to 6.9 ms.
