Scorpio gets a bigger sting

Western Digital launches its largest ever capacity notebook drive with the introduction of the 320GB Scorpio

In a bid to satisfy the need for larger notebook storage options, Western Digital has begun shipping its 320Gbyte Scorpio hard drives, the firm's highest ever capacity models for notebooks.

This newest variant of the Scorpio line makes use of the standard 2.5-inch notebook form factor and is compliant with the latest specification of the Serial ATA interface - allowing for a maximum transfer speed of 3Gbits/sec between the drive and the motherboard's Serial ATA controller.

The drive also makes use of a 5400rpm spindle motor and boasts 8Mbytes of cache memory to help improve reading and writing performance.

In terms of spindle speeds, the Scorpio is currently outclassed by Hitachi's Travelstar and Seagate's Momentus lines, which offer models with 7200rpm spindle motors (the faster the spindle motors, the faster a drive performs). On the capacity front however, the 320Gbyte Scorpio drives is larger than the biggest drives in both Hitachi and Seagate's 2.5-inch lineups.

Notebook manufacturers such as Acer have already begun outfitting their notebooks with WD's new Scorpio drives. Users will also be able to upgrade their existing notebooks by purchasing these drives as standalone upgrades, through Western Digital's website or via the firm's dealer network.
