Really, one terabyte isn’t enough? If so, you’ll be pleased to know that your insatiable need for more digital storage has left Seagate no choice but to announce the world’s first 1.5TB hard drive. The half-terabyte jump over previous highest capacity 1TB drives, Seagate is happy to point out, represents the largest jump in capacity in hard-drive history. The 3.5-inch Barracuda 7200.11 uses perpendicular magnetic recording, which squeezes more 1s and 0s per square inch than conventional drives, to pack 1.5TB of storage space over four platters. Seagate isn’t sharing pricing details yet. The drive will begin shipping in August.
