As a laptop lover, its music to my ears to hear that the venerable Seagate has released and begun to ship a 160GB notebook drive. The drive utilises the perpendicular recording technology, and operates at 5,400rpm. Known as the Momentus 5400.3, the drive aims to minimise power requirements and extend battery life. It uses an Ultra ATA 100 MB/second interface. There is a SATA version planned for release later in this year.
