Performance in Intel IOMeter: Sequential Read and Write Patterns

In order to better study all the nuances about the hard disk drives performance, we tested the sequential read and write speeds, which showed how quickly the testing participants can process ordered requests with linearly growing address. The obtained results are given in the table and on the diagrams below.

Let’s start our discussion with the sequential reading. The diagram above shows that WD2500SD is the winner. It outperforms its opponent as a single drive as well as in the array. It manages to achieve its maximum advantage when working with 4Kb and 8KB data blocks. The overall advantage in sequential read speed is seen when working with the data blocks from 2KB to 1024KB.

The next diagram reflects the sequential write speed of the testing participants. Here the laurels are again won by WD2500SD HDD. This solution is more efficient in both cases than its rival, especially when we have an array. It yields a little bit only in the regular work mode when processing 1KB and 2KB data blocks.
