The Deskstar 40GV really starts to shine in IOMeter. A quick glance at the table shows the 40GV as having the highest number of I/Os per second under all loads and access patterns.
Interestingly, the 5400 RPM Seagate U5 does not seem to fare as well compared to the 4500 RPM Fireball lct20, generally scoring lower except under the Video Workstation access pattern. The purpose of the Video Workstation access pattern (which consists of 100% sequential writes) is to simulate a digital NLE environment, where video is captured to the hard drive. Thus, the faster a hard drive can write, the more suitable it is for storing bandwidth intensive data like digitized video. This seems to be more of Seagate's forte.
