Rating : - Does what a hard drive should
Picked this up for use as a backup disc for a MacBook using Apple's Time Machine. Runs flawlessly off bus power directly from the laptop. Running without a hitch for nearly 3 months at this point and warrantied for 3 years. Sleek, small, convenient. Have several WD externals and no complaints yet. Well worth it.
