Seagate recently unveiled the world's first 1.5-terabyte desktop and half-terabyte notebook hard drives. The 3.5-inch Barracuda 7200.11 packs 1.5TB onto four platters and delivers a sustained data rate of up to 120MB/second. The 2.5-inch Momentus 5400.6 and Momentus 7200.4 are available in capacities up to 500GB and are tough enough to withstand up to 1,000 Gs of shock. The Momentus 7200.4 also offers a 7200-rpm spin speed and a 16MB cache.
The debut of the Barracuda® 7200.11 1.5TB hard drive, the eleventh generation of Seagate’s flagship drive for desktop PCs, marks the single largest capacity hard drive jump in the more than half-century history of hard drives - a half-terabyte increase from the previous highest capacity of 1TB, thanks to the capacity-boosting power of perpendicular magnetic recording (PMR) technology.

The Barracuda 7200.11 hard drive combines proven PMR technology, components and expert manufacturing to provide 1.5TB of reliable storage for mainstream desktop computers, workstations, desktop RAID, gaming and high-end PCs, and USB/FireWire/eSATA external storage.

Seagate’s new 2.5-inch half-terabyte 5400- and 7200-rpm drives - Momentus® 5400.6 and Momentus 7200.4 - deliver the best combination of capacity, mobility and durability for mainstream and high-performance notebook computers, external storage solutions, PCs and industrial applications requiring small form factor.
The Barracuda 7200.11 1.5TB will ship to retailers in August 2008. The Momentus 5400.6 and 7200.4 hard drives are scheduled to ship some time during the fourth quarter of 2008. If you'd like to read more, Seagate's entire press release can be found here.
