Best External Hard Drive Value

Macworld compared the speed and overall value of seven external hard drives with capacities of 750GB or 1TB, and chose Western Digital’s My Book Studio Edition ($320/1TB) as the best value.

OWC’s Mercury Elite-AL Pro was the fastest in many tests, but it costs $420, $100 more than the Western Digital drive. Both feature four ports: USB 2.0, FireWire 400, FireWire 800 and eSATA (in order of increasing speed).
