Workstation Pattern

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

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

Rating (Workstation) = 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.

The HDD from Western Digital wins the full-capacity test but the HM250JI is close behind. The other 5400rpm drives are slower and equal to each other.

It’s different when the test zone is limited to a 32GB partition: the two groups change places, the Hitachi becoming the leader and the Samsung sinking to fourth place. The MHX2250BT is the slowest of all again.
