Hitachi has happily launched a trio of 3TB hard drive solutions, available as internal drive kits, external desktop drives or OEM models for manufacturers and PC system builders. The new Deskstar will be available in capacities of 2TB and 3TB and will offer a 64MB buffer and 6Gb/s SATA interface. The Hitachi XL desktop external drives will be available in capacities of 1TB, 2TB or 3TB and offer USB 2.0 connectivity, though we’d much rather have a USB 3.0 connection. The OEM drives will be available in capacities of 1.5TB, 2TB and 3TB. The Hitachi XL external hard drives are already available at $100, $170 and $250 for the 1TB, 2TB and 3TB variants respectively.
