Sample disk results
Here's a summary of what was measured for the laptop drive tested in detail previously, as well as a desktop drive both alone and in a RAID array as a second useful data point:

Note how all the seek-related information is reported here relative to the size of the area being used to seek over. This is a good habit to adopt. Also note that in the laptop rate, two commit rates are reported. The lower value is without the write cache enabled (just under the rotation rate of 120 rotations/second), while the higher one has it turned on—and therefore providing an unsafe, volatile write cache.
The other two samples use an Areca ARC-1210 controller with a 256 MB...
