HD Tach Tests
HD Tach tests 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.
This benchmark is intended to determine the maximum read or write speed on the device at various locations. Hard drives, for example, have faster read/write speeds at the inside edge (mapped to block 0) of the device, so it is useful to see the difference in speed. The maximum sustained speed (lowest speed on the device) is an important metric for real time sequential access applications. The maximum speed may be important to a power user that would like to partition the drive into a high speed partition and low speed partition.
The performance is highly dependant to the HD you will use. For our tests, we present how the NexStar 3 performs with an 80GB HDD installed and we compared it with TEAC'sHT-15OT which has exactly the same HDD.
Vantec NexStar 3
The Vantec NexStar 3 reported good performance. It would appear that the VIA chipset used in the TEAC HT-15OT, is responsible for the higher transfer rates.
