Seagate consistently snags the largest slice of the hard drive market, and it was the first manufacturer to push capacities to 750GB. However, the company has been slow to the terabyte mark, handily beaten to the punch by Hitachi's Deskstar 7K1000. Western Digital recently pulled up to the terabyte table with its Caviar GP, too, leaving Seagate's brand-new Barracuda with fresh competition in the high-capacity game.
In some ways, the new 'cuda combines the best of what you get with the Deskstar 7K1000 and Caviar GP without the baggage inherent to each. The Deskstar, for example, is blessed with a massive 32MB cache and speedy 7,200-RPM spindle speed, but needs five relatively low-density 200GB platters to reach the terabyte mark. The Caviar, on the other hand, spreads its terabyte over just four 250GB platters, but its performance is hampered by spindle speeds that dip below 7,200-RPM.
