Seagate announced their 1.5 Terabyte, 3.5-inch version of the Barracuda 7200.11. The drive’s storage capacity which is 500GB more than any 3.5-inch desktop hard drive, is accomplished through refinement of perpendicular recording that allows 375GB of data to fit on each of the drive’s four platters.

The drive’s fast Serial ATA II interface delivers an industry-leading sustained data rate of up to 120MB/second for fast boot, application startup and file access. The 3.5-inch drive is also offered in capacities of 1TB, 750GB, 640GB, 500GB, 320GB and 160GB with cache options of 32MB and 16MB.

Seagate also developed a new unit, a 500GB, 2.5-inch laptop drive under their Momentus line of drives in both 5400RPM and 7200RPM flavors with 16MB of cache.
