It's about time. Hitachi may be the granddaddy of perpendicular media (if not, they're certainly the technology's biggest booster), but the company has been a little slow to shrink its high-capacity drives down to 2.5 inches. But the company is now prepared to follow such competitors as Seagate and Toshiba, with its own 160GB, 2.5-inch drive. The 5400RPM Travelstar 5K160 drive is expected to sell for $270 to OEMs and $300 to consumers. Hitachi plans a 1.8-inch version by the end of the year; they're playing catchup there as well, since Toshiba's 1.8-incher is already on the market.
