Performance in WinBench 99

I ran WinBench 99 to create data-transfer diagrams for the Western Digital drive. These are indicative of the effective bandwidth of each of its interfaces.

USB 2.0

FireWire 400

FireWire 800

These diagrams prove the high efficiency of the FireWire 800 interface. It allows the WDG1T5000N to show its full speed – the graph starts at a point of about 75MB/s! The diagrams for FireWire 400 and USB 2.0 show a nearly straight line, which means that the interface limits the drive’s speed. This is especially conspicuous with USB 2.0.
