Performance in Intel IOMeter Sequential Read and Write Patterns

The low-level Intel IOMeter benchmark was used to test the linear read and write speed of the hard drives. During the test session there was a stream of read/write requests sent to the drives with the queue depth=4. The data block size changed every minute. As a result we can see the dependence of the linear read/write speed on the data block size.

At first let’s take a look at the linear read speed. On the first diagram we can clearly see that the performance difference between the Seagate Momentus 5400.3 (ST9160821A) and the rest of the test participants. The new HDD is evidently faster than the opponents when we come to the data block size of 8KB and up.
