Seagate this week began shipments of the the Barracuda XT hard drive - a product that eliminates the need to purchase extra hardware or software to overcome the 2TB barrier. Legacy PC BIOS designs and device drivers and older operating systems such as Windows XP are incapable of using hard drive capacities beyond 2.1TB. The upshot is that existing desktop drives with more than 2.1TB of storage capacity must be deployed with additional software or hardware and may also require extra device drivers to overcome this limitation.

The Barracuda XT hard drive with free Seagate DiscWizard software is a complete solution. DiscWizard software makes it simple to configure the computer operating system and device drivers to access the full 3TB of capacity on legacy systems using Windows XP and PC BIOS and on personal computers equipped with newer versions of Windows or the new UEFI BIOS. The new DiscWizard software is available for free download at www.seagate.com/beyond-2TB.

The Barracuda XT hard drive combines a 64MB cache that optimizes burst performance in cache-intensive applications such as PC gaming and nonlinear video editing with Serial ATA 6Gb/s. The 3.5-inch, 7200RPM drive's 3TB of storage capacity gives desktop PC users the most space ever available for videos, games, photos and files.

The Barracuda XT 3TB hard drive launch comes only months after Seagate introduced the Barracuda Green hard drive. The eco-friendly Barracuda Green hard drive features Seagate's SmartAlign technology to enable all the benefits of the new 4K sector standard while simplifying drive installation. SmartAlign technology works by eliminating the need for utilities often required to ensure optimum drive performance.
