Mac External Hard Drive
Extend the storage space on your computer and back up your important files with the CACE Series external hard drive. This drive is designed for ease of use with a Mac and is fully compatible with Time Machine®. The drive is Plug-and-Play with Mac, and with FireWire 800 you get blazing transfer speeds of 800 Mbit/s, almost double that of USB 2.0.
With two FireWire 800 ports on the drive, you can daisy-chain your FireWire devices together so you will not run out of FireWire ports on your computer. For example, you can connect the hard drive to your computer and connect a camcorder to the open port on the hard drive. That way, this setup requires only one FireWire port on your computer instead of two.
