Western Digital releases 1TB laptop hard drive
Published: 28 Jul 2009 08:53 BST
Western Digital on Monday announced two laptop drives that offer "extreme" amounts of storage: the Scorpio Blue 1TB and the Scorpio Blue 750GB. Prior to this announcement, the largest laptop hard drive available was 500GB.
The largest desktop hard drive currently on the market is 2TB. The Scorpio Blue 1TB drive, though half the capacity, is still impressive considering a 2.5-inch laptop drive is much smaller than a 3.5-inch desktop drive.
The new WD laptop drives are the first that use 333GB per platter technology.
The Scorpio Blue hard drives support the Sata 2 (3Gbps) standard but have a thickness of 12.5mm, as opposed to 9.5mm in other 2.5-inch drives. This means the new drives will not fit in all 2.5-inch slots in laptops.
For this reason, WD designates them as a perfect fit for portable storage solutions, and they will be used in WD's new My Passport Essential SE Portable USB drive.
Other than capacity, the new Scorpio Blue drives also feature a set of advanced storage technologies, including the following:
- WhisperDrive, which is WD's technology that uses seeking algorithms to produce one of the quietest 2.5-inch drives available.
- ShockGuard, which helps the drive better withstand shock, such as accidental drops and vibrations.
- SecurePark, which is a mechanism that parks the recording heads off the disk surface during spin up and spin down and when the drive is off. This ensures that the recording head never touches the disk surface to improve long-term reliability.
Both new drives come with 8MB of buffer memory and spin at 5,200rpm, which is slightly slower than the 5,400rpm speed of mainstream laptop drives.
The Scorpio Blue 750GB drive (model WD7500KEVT) is available now and costs $190 (£110). The 1TB version (model WD10TEVT) is, for now, only available configured into the My Passport Essential SE USB drive, but it will be available as an internal hard drive in a few weeks. It will cost $250.
