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.

HDTach is one of the standard benchmarks for storage devices and it shows an interesting story for the OCZ 64GB SSD.  The burst speed of the drive is pretty low; only 59.8 MB/s.  That is well below even the WD Scorpio drive and compared to the new WD VelociRaptor it doesn’t even come close.  The average transfer rates on the SSD are mixed with a read speed of 54.1 MB/s and write of only 26.9 MB/s. 

Where the drive is really impressive is in the random access time – at only 0.2 ms it is in another world when compared to platter-based hard drives.  The reason for this is the fact there is no read head that needs to move to location before data can be “drawn” from the drive.  So while the OCZ SSD can GET to data world’s faster than the competition it’s the MOVING of large amounts of that data that the SSD falters in.
