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.
The OCZ Apex 250GB SSD actually has a very good showing here in our HDTach results that includes a burst speed of over 232 MB/s (not far behind the Intel drive). When we look at the average transfer speeds the Apex drive is again impressing with a higher write speed than the Intel X25-M drive can pull off and much faster read and write speeds than any single spindle-based HDD result.
