If you're looking for information on the ultimate mobile ATA hard drive, our friends at the Tech Report have the scoop. Geoff just posted up a mobile hard drive round-up that'll arm you with the information you need to make an educated purchase.
"To gain a better understanding of how the performance of today's latest and greatest 2.5" mobile ATA drives looks, we've gathered seven drives from the likes of Fujitsu, Hitachi, Seagate, and Western Digital. This mix of drives includes a little of everything, including a 160 GB perpendicular monster and a couple of 7,200-RPM speed demons. We've also thrown in a lowly 4,200 RPM drive that will serve as a handy reference point for anyone considering upgrading their laptop's hard drive. Join us as we subject this collection of drives to a punishing array of performance, noise level, and power consumption tests in search of the ultimate ATA laptop drive."
