The diagram with the overall performance indexes shows very clearly that in case of USB 2.0 interface, the performance difference between the two solutions makes more than 1.5 times. This is exactly the advantage of WD solution over the one from Maxtor.
Integral performance coefficients for the drives connected via the FireWire interface indicate a performance growth by Maxtor 5000DV compared with the USB 2.0 case, which makes the relative gap between the rivals not so significant any more.
When we use 32GB logical drives for our tests we can notice a natural performance increase by both HDD models. When the drives work via the USB 2.0 interface the requests processing speed remains almost constant independent of the queue depth. As usual, WD2500B007 HDD looks more attractive than the competitor from Maxtor.
The drives working with FireWire interface show higher performance than in case of USB 2.0, starting with queue=16 requests.
The diagram with the overall performance indexes demonstrates that when the drives work via the USB 2.0 interface, WD2500B007 appears more efficient as a solution for a workstation disk subsystem.
Integral performance indexes for FireWire interface show that the performance gap between the rivals has become smaller, though WD2500B007 is still ahead of Maxtor 5000DV.
