Workstation Pattern

The Workstation pattern simulates the typical load on a workstation at request queue depths up to 32. This test was performed on the full capacity of the drives as well as on a 32GB partition created on them.

To calculate the overall performance rating of a drive in this test, we use the following formula:

Performance = Total I/O (queue=1)/1 + Total I/O (queue=2)/2 + Total I/O (queue=4)/4 + Total I/O (queue=8)/8 + Total I/O (queue=16)/16 + Total I/O (queue=32)/32.

When the entire storage capacity of the hard disk drive is involved, Passport 250GB outperforms the younger model, just like in the previous tests.

When we reduce the partition in question to 32GB, the gap between the testing participants increases even more.
