And Hitachi makes three. Crashing Samsung's and Fujitsu's 9-mm thin, 250GB laptop disk party is Hitachi's new TravelStar 5K250. Spinning at 5,400rpm, it brings along your choice of SATA 3Gbps and 1.5Gbps interfaces, an 11-ms mean seek time, 8MB data buffer, 24dB rattle when idle (26dB operational), and 1.8W average power draw during read/write cycles. Pretty consistent with the others until you factor in Hitachi's optional Bulk Data Encryption to safeguard data from loss or criminal harvesting. Shipping in volume today for an undisclosed price.
