Seagate launch Barracuda XT with 3TB storage capacity which is now the highest available capacity for desktop PCs.
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.
However, using their own proprietary onboard software Seagate have overcomes this hurdle making the Barracuda XT work on existing PCs without issue. We’re hoping to get one of these drives in to test when they are available.
