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.

"Windows Vista," you cry, "What about Windows XP?" Good question. Samsung announced its HHD (Hybrid Hard Disk) at WinHEC in May and made it clear that the drive would only be available in OEM PCs that are supplied with Windows Vista as the HHD was developed in co-operation with Microsoft.

Seagate seems to be taking a different line by directing its interest towards the notebook drive market as shipments are growing like crazy while the desktop drive market is flat.

Hybrid technology brings an extra benefit to the mobile sector as the drive can stop spinning once your files are loaded, reducing hard drive power consumption by 50 per cent, however, the Vista tie-in suggests that the Momentus PSD won't ship until January 2007. We've put a call in to Seagate and are waiting to hear what benefits, if any, hybrid technology brings to Windows XP. Read the rest of the news here.
