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 see the results of linear reading. The best result here belongs to Western Digital Wd1200VE HDD. Out of four hard drives we are paying special attention to today, it looks best of all. It outperforms Samsung HM120JC when working with smaller data blocks and runs almost equally fast with the Samsung solution in all other cases. At the same time, it yields to the linear read speed leader – the Seagate ST9160821A HDD. Both 100GB models from Samsung and WD run slower than their elder brothers, but the Western Digital WD1000VE is again performing linear reading faster than the Samsung HM100JC fellow. They have also turned out the slowest of all the hard drives we looked at today.
The general picture has hardly changed if you look at the diagram with the linear write speed measurements. Once again Western Digital WD1200VE and Samsung HM120JC manage to achieve much higher results than their 100GB counterparts. At the same time the WD HDD is once again doing better than the Samsung one thanks to more convincing results when working with data blocks of smaller size. The Western Digital WD1000VE is also achieving a convincing victory over the Samsung HM100JC. As we can see again, even the fastest solutions from the four HDDs in question cannot compete with the leader – Seagate ST9160821A.
