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.

Just four points separate the fastest drive from the slowest in WorldBench, with the Caviar Black 2TB sharing the lead with Seagate's Barracuda 7200.12.

Among WorldBench's multimedia editing and encoding tests, only Photoshop performance really seems to be affected by our choice of hard drive. The two-terabyte Black takes the lead in that test, followed closely by its predecessor and then a Caviar Green.

Scores are very close through WorldBench's office and multitasking tests.

In the Nero test, the Caviar Black 2TB pulls up a little short of the 7200.12. The new Black is faster than the old model, though.
