Verbatim Americas today launched a new line of SmartDisk 2.5″ Portable Hard Drives (HDs). With the newly designed drives, consumers and businesses can add 120, 160, 250, or 320GB of removable capacity without having to open their computer. Verbatim has enhanced the versatility of its 2.5″ SmartDisk HDs by offering them with choice of a USB interface or a Combo USB/FireWire interface. With the Combo USB/FireWire interface, the device also becomes interoperable and files can be transferred between a Mac and a PC. The palm-sized external drives will be available for both Windows and Mac users later this month with retail prices starting at US$99.
