Performance in Intel IOMeter WorkStation Pattern
With the help of this pattern the benchmark imitates the workload typical of a regular workstation, which is limited at 32 requests queue. The results were taken for the drives formatted as a single partition, and as a 32GB partition.
This graph demonstrates the performance of our hard disk drives when they work via USB 2.0 interface. WD2500B007 is an indisputable leader here. It is especially evident for queue=1 and then the advantage gets somewhat smaller as the queue depth increases.
As soon as we shift to FireWire interface, the performance of our drives grows up significantly when the queue reaches 16 requests. The reason is probably the same: IEEE1394 controller knows to arrange the request queue the right way to ensure optimal performance. WD2500B007 looks bets of all here.
