Seagate wasn’t the first to the 7,200rpm mark, but that hasn’t stopped it from making the fastest hard drive around. The Momentus 7200.2 has a well-deserved reputation as the notebook hard-drive performance king. What you give up in space, you gain in speed—the Momentus easily eclipses the ginormous Western Digital Scorpio in read speed, access time, and all around zippiness. (Seagate has announced but not shipped a 200GB version of this drive.)
Western Digital has pulled off a significant coup with its 250GB Scorpio notebook hard drive; the device is the current capacity champion. (Fujitsu has also announced a 250GB drive but has not shipped it yet.) Packing 250GB into two platters, the areal density of the Scorpio easily outstrips that of the other hard drive reviewed here—Seagate’s two-platter 160GB Momentus drive.
