Seagate ships 7,200RPM 3TB Barracuda XT internal hard drive, we wonder what took so long

We've been hearing about Seagate's plans to offer an unencumbered 3TB hard drive since May of last year, but despite promises of a 2010 launch and the release of similarly large HDDs from companies like Western Digital and Hitachi, we're only now seeing the 3TB Barracuda XT shipping all on its own. We won't claim to have an explanation for the delay, but it's possible that the company's proprietary software -- which breaks the 2.1TB legacy OS barrier and enables this guy to function within Windows XP -- could have something to do with it. It might be tardy to the party, but the new Barracuda can definitely hold its own when stacked against the competition -- it spins at 7,200RPM, touts a 64MB cache, and plays nice with the 6Gbps SATA interface. It ain't the only 3TB fish in the sea, but at $280, it's definitely not dead in the water.
