Teac HD 15OT & HD-15 PUK A

3. HD Tach

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 systems 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 80GB HD had a slightly higher average reading speed while burst speed was much higher than the 60 GB HD. According to HD-Tach, the FUJITSU MHT2080AT that comes installed in the HD 15OT is an overall faster hard disk than the FUJITSU MHV2060AT.
