Western Digital offers its Western Digital My Book Studio LX 1TB FireWire 800 / USB 2.0 External Hard Drive, model no. WDBACH0010HAL-NESN, for $99.99 with free shipping ($0.10/GB). That’s tied with last week’s mention and the lowest total price we could find by $19. This drive runs at 5400 rpm and includes a “smart display” that shows the capacity and storage status even when the drive is unplugged. Although formatted for Macs, it can easily be reformatted for a PC.
