A new capacity and performance ceiling has been set in the world of 5400 RPM 2.5" HDDs.  The Seagate Momentus 5400.3 not only has the biggest space amongst all shipping parallel-ATA 2.5" HDDs, but also performed extremely well.  Looking back at smaller 5400 RPM drives, the 5400.3 exceeded them in nearly all test categories.  Best of all, the 5400.3 is backed by a 5-year warranty.
