Ziff Davis' WinBench 99 includes three benchmarks, which are valuable for hard drive tests: The Disc Inspection Test, as well as the Business and High-End WinBench. The Business WinBench for hard drives is something like the SYSmark for complete systems: It will give you a good impression about the drive's performance under real life conditions. However, you should never base a buying decision on just one single benchmark. This one uses the same applications that run in WinStone 99.
High-End Disk Winmark
The high-end version of the Disk WinBench runs simulations based on professional applications. This time Quantum is able to beat the rest with their new Fireball Plus AS.
