IPEAK/Heat Tests

- Combined Read/Writing Tests

Intel's IPEAK test results combine both reading/writing actions and give a weighted score based upon each drive's performance in each specific task. The height of each bar is the measured mean service time per disk access for a drive stimulated with I/Os from the given workload. Shorter bars represent better performance. As we will see a drive that scores well in the "Desktop" test doesn't mean that will perform the same in the "Server" mode test, since the I/O operations are different.

In the above picture you can see the weighted (Average) score of all tested drive. WD1200JB scored high enough to give a very low IPEAK Desktop weighted score of 1.14. This is due to higher reads vs. writes at the "Desktop" test. In the "Server" test, the drive delivers the lowest mark but with lower performance difference than in the previous test.

- Heat Tests

The drive doesn't support such feature through the DTemp software.
