Seagate Barracuda 7200.10 750GB Hard Drive
HD Tach 3.0.1
The four HD Tach metrics that we sampled for each drive are Random Access, which is largely dependent on spindle speed of the drive, Read Average, Write Average and Burst Read throughput. Again, Read and Write Average scores are what we would consider the most meaningful to the end user. On the other hand, Burst Read is typically tied to a drive's on-board cache and SATA interface speed.
This is more along the line of what we expected after seeing the Sandra results, at least when looking at the transfer speeds. Here we are most interested in the Average Write and Average Read marks as well as the Random Access time. The 7200.10's Average Write and Read scores are pretty good, especially Average Read. The drive's Burst Read is quite impressive, but this doesn't mean as much to the end-user in the real world. Unfortunately, the Random Access time posted by the 7200.10 was the slowest of all three drives.
