Western Digital 2TB My Book World Drive Uses One Single 2TB DiskS

Western Digital's hit 2TB on their external drives before, but this is the first time they've done it using one single 2TB disk.

By using a 2TB disk instead of, say, two 1TB disks, the drives take up less space on your desk and are generally simpler (one instead of two). These will hit the My Book Studio, My Book Mac, My Book Home and My Book Essential editions of Western Digital's lineup.

My Book Studio Edition & My Book Mac Edition
Formatted[1] for Mac computers, these drives are an ideal solution for creative professionals and video editors. The My Book Studio Edition is equipped with high speed FireWire® 400/800 and eSATA interfaces as well as the popular USB 2.0 interface and a 5-year limited warranty. My Book Mac Edition external drives feature a USB 2.0 interface and a 1-year limited warranty.

My Book Home Edition
Equipped with continuous backup software and high-speed eSATA and FireWire 400 as well as USB 2.0 interfaces, My Book Home Edition carries a 3-year limited warranty. My Book Home Edition is designed for PC users that need an effortless way to preserve digital pictures.

My Book Essential Edition
My Book Essential Edition offers an easy way to add storage capacity to home or office computers. The drives are equipped with a USB 2.0 interface that provides convenience and compatibility among multiple computers.
