Performance in Intel IOMeter Sequential Read & Write Patterns

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

On the first graph we see that the Scorpio drive yields only to the Seagate ST9100823A and shows about the same linear read speed as Hitachi HTS541080G9AT00. I would also like to note that in case of smaller data blocks processing, it is also defeated by Samsung MP0804H.

The second diagram shows the linear write speed. Scorpio drive managed to become the leader when working with smaller data blocks (up to 4KB inclusive). Then, starting with 8KB data blocks, it moves to the stable second position after Seagate ST9100823A.
