Seagate's Momentus XT Reviewed, Finally a Good Hybrid HDD

The promise of Hybrid HDDs has come and gone with no champion. Today Seagate is announcing its Momentus XT, a 2.5" 7200 RPM notebook drive (9mm form factor) with 4GB of SLC NAND on board used as a read cache for frequently accessed data. The end result is a notebook drive with notebook power characteristics that performs like a 10,000 RPM VelociRaptor. We finally have something in between a HDD and SSD for those who need more space on a single drive than a SSD can affordably offer.
