WorldBench
WorldBench uses scripting to step through a series of tasks in common Windows applications. It then produces an overall score. WorldBench also spits out individual results for its component application tests, allowing us to compare performance in each. We'll look at the overall score, and then we'll show individual application results.

WorldBench's overall score suggests that the Barracuda XT isn't any faster than the Caviar Black when working with common desktop applications. Let's dig into the individual application tests for a closer look.

The 'cuda is a little slower than the Caviar in Photoshop. Note that there isn't much difference in drive performance between Intel's P55 3Gbps controller and the 6Gbps Marvell chip.

The results of WorldBench's office and multitasking tests are pretty much a wash.

In Nero, however, the Barracuda notably trails the Caviar Black when the Western Digital drive is hooked up to the Marvell controller. If you're running on the P55, though, the 'cuda's a little quicker than the Caviar.
