Performance in Intel IOMeter DataBase Pattern

Let’s start with DataBase pattern. With the help of this pattern we will find out how fast the HDDs will process requests with different queue depth and writes share.

In order to illustrate the behavior of our testing participants (their work via USB 2.0 and FireWire interfaces) we made three graphs for various queue depths.

Let’s start with USB 2.0:

The first graph illustrates the HDDs performance under linear workload (queue=1). You can see that WD2500B007 is an indisputable leader here. No matter how big the share of write requests is, it is still faster than Maxtor 5000DV.

The second graph shows how fast the drives work with queue=16. As we see, nothing has changed. WD2500B007 is still far ahead of the opponent.
