ACDSee PowerPack

Photoshop doesn't prefer one hard drive over the others, but ACDSee definitely has a taste for Caviar. The 750GB SE16 bests the Raptors by more than 10 seconds here, and it's more than 20 seconds ahead of the 'cuda.

The Caviar SE16 750GB doesn't score any wins in WorldBench's multitasking and office application tests, but scores are pretty tight all around.

WinZip and Nero both exploit faster drives, and the 750GB Caviar turns in the quickest time in each test. Its margin of victory is particularly impressive in Nero, where the fastest Raptor trails by 17 seconds.
