Take that WD, Toshiba, and Hitachi. Fujitsu just returned from exile with a claim to the biggest fastest laptop-disk throne. The 3Gbps SATA-equipped MHZ2 BJ series measures in at a standard 9.5-mm and spins at 7,200rpm with a 16MB cache and 25dB idle noise level. Average seek times are listed at 10.5-ms for data reads and 12.5-ms for writes while drawing 2.3 watts of power. Oh sure, a couple of 2.5-inch 500GB disk drives have already been announced. But most of those measure in at a non-standard 12.5-mm making them unsuitable for the majority of laptops on the market today. Sales of the new MHZ2 BJ-series begins in June.
