Seagate is definitely positioned to become an even bigger player in the world of mobile hard drives.

Seagate has launched three new families of notebook hard drive under the Momentus monicker. The most radical drive is the hybrid Momentus 5400 PSD (Power-Saving Drive) which adds 256MB of Flash memory to a 5,400rpm SATA300 2.5 inch hard drive.

The Momentus also has 8MB of conventional cache memory. The highest capacity model of PSD will achieve 160GB of storage with two platters and four read/write heads.

Non-volatile Flash memory can be used to store system files to allow Windows Vista to boot faster as the notebook can load files into system memory before the drive platters have started to spin. Seagate claims the drive allows Vista to resume from hibernation 20 per cent faster than a conventional hard drive…. Source: Reg Hardware
