Step aside Fujitsu, there's a new 2.5-inch hard disk champ on the block by way of Toshiba. A world's first 320GB 2.5-inch drive, in fact. The MK3252GSX drive spins a pair of 160GB platters at 5,400rpm with an 8MB buffer and 12ms average seek time over a 3Gbps SATA interface. So yeah, it's just 20GB more data that the Fujitsu 300GB disk but that HDD spins at just 4,200rpm. Better yet, The Tosh drive stands just 9.5-mm tall -- a full 3-mm less than Fujitsu's 300 gigger; that's about as thin as it gets in these 2.5-inch laptop drives. Look for the 320GB disk as a factory shipped option around November when Toshiba starts turning 'em out for mass production.
