Data Transfer Test: WinBench 99 Disc Inspection Test
Here you can see which drives are the fastest - and which one are the slowest. Some applications will run better is the difference between minimum and maximum transfer speed is not too big (e.g. Quantum).
The Seagate and Fujitsu hard drives are the clear performance winners here, while these numbers don't always reflect real world performance, as we can see with the Western Digital drives.
