Seagate today preempted CES by launching a major update to its Barracuda drives. The 7200.12 is the first desktop hard drive to fit 500GB of data on to a single platter and manages to hold 1TB by using just two platters versus as many as four on other disks. Condensing the data improves reliability by reducing the points of failure and also improves performance through sheer density. Seagate itself estimates sustained transfer speeds of 160MB per second and thus competes more closely with some solid-state drives.
The incident is unlikely to help Microsoft gain ground against Apple's iPod, which accounts for about three-quarters of the digital music player market.
