Tom's Hardware has benchmarked four 2.5" Hard Drives From 500 GB To 1 TB

Over the past few years, 2.5" hard disk capacities have grown by leaps and bounds. And although they're still typically slower than 3.5" drives, performance in the 2.5" form factor continues to increase due to higher data density. Today, even 2.5" drives positioned as quiet energy-savers manage sequential transfer rates over 85 MB/s, while more performance-oriented disks sport transfer rates just shy of 100 MB/s.

We're adding four new drives to our 2012 Mobile Hard Drive charts: Hitachi's Travelstar 7K750 and Travelstar 5K1000, Toshiba's MQ01ABD100, and Western Digital's Scorpio Blue WD5000LPVT. Among these four models, only the Travelstar 7K750 is performance-oriented. The Travelstar 5K1000, Toshiba's disk, and the Western Digital drive are “green” offerings that focus on low noise and low power draw.
