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.
Again our results with HDTach show the Summit drive to be a terrific performer. The burst speed, though a less important number with flash-based storage, is still nearing the maximum of the SATA 3.0 Gb/s bus. Average transfer speeds are VERY impressive including the 172 MB/s write speed that is nearly 100 MB/s faster than the rated speeds on the Intel X25-M.
