Performance Test
This test checks the performance of your hard disk. It
determines the data transfer rate and track-to-track seek time
based on the transfer size, seek count, and the amount of data
transferred.
The interleave factor is the most critical factor in determining
disk performance. Changing the interleave factor can drastically
change disk performance.
The program measures the data transfer rate in kilobytes per
second. To measure the data transfer rate, the program reads
64KB of data 15 times and counts the number of timer ticks
using this formula:
Transfer rate = (64KB x 15 x 18.2) /# timer ticks
The program measures track-to-track seek time in milliseconds
using this formula:
Seek time = (#timer ticks x 1000) / 18.2 x 200
The number of seeks is 200.
A higher data transfer rate and a lower seek time indicate better
disk performance.
