Seagate reveals first 1.5TB drive, more

updated 10:25 am EDT, Thu July 10, 2008

Seagate Barracuda 1.5TB

Seagate today broke through a long-held barrier and released a 1.5 terabyte version of the Barracuda 7200.11. The storage is 500GB more than any other 3.5-inch desktop hard drive and is accomplished through extra refinement of perpendicular magnetic recording that allows it to fit 375GB on each of its four platters. The density also helps improve speed and lets the disk transfer data at a sustainable 120MB per second, or higher in bursts thanks to the extra bandwidth of its Serial ATA II connection.

The top-range Barracuda holds 32MB of cache and will be available in August at an unknown price by itself as well as built into future desktop systems. The remaining drives between 160GB and 1TB will remain in the lineup.

On top of the new flagship drive, Seagate additionally has two new Momentus 2.5-inch drives for notebooks. The 7200.4 is the first known hard drive in the class to carry 500GB but spin at the same 7,200RPM as desktop hard drives, essentially providing no compromises either in space or speed; it also carries 16MB of cache to cut down on unnecessary drive access. The 5400.6 delivers the same 500GB at a more common 5,400RPM speed and with 8MB of cache.

The two portable drives are due sometime in the fall.

    It seems

    hard drives are always announced but always shipping "sometime" in the spring/fall/summer/winter. And even then, they never ship.

    Why not just say, "we are coming out with a 10 TB drive sometime in the next few years?

    It always excites me to see hard drive news but then I am always let down to see they are not shipping immediately.
