Storage maker Fujitsu today said that it has set a new record for capacity in 2.5-inch notebook hard drives. Its new MHX2300BT series of disks uses perpendicular magnetic recording to achieve an unprecedented 300GB of storage, beating the company's earllier peak of 200GB set in March. Although it spins at 4200RPM, the new drive's increased density is said to improve speed without affecting power consumption: its 1.6W of power draw during active use is the best in its class, Fujitsu claims. The MHX line consumes as little as 0.5W when idling and is one of the few notebook-class drives to support Native Command Queuing for faster and more intelligent data loading. Fujitsu hopes to ship the drive in notebooks and other portable devices by early 2007 and will accompany the launch with a less expensive 250GB model using the same technology.
