With up to 6TB of storage and support for both RAID 0 and RAID 1, the My Book Studio Edition II is the largest dual-bay external hard drive to date, in terms of storage space. It comes with multiple types of peripheral connections and allows users to replace its internal hard drives easily, as long as they use PowerGreen hard drives made by Western Digital. Unfortunately, the drive doesn't support USB 3.0 and takes a long time to be recognized by a computer or to come out of sleep mode.
To make up for this, it offers fast performance and comes with a price tag that won't break the bank at just around $500 for 6TB (or $270 for 4TB and $180 for 2TB). If you're looking for a large and easy-to-use external hard drive for your desktop computer, especially a Mac, the My Book Studio Edition II is worth consideration.

The My Book Studio Edition II has exactly the same design as the previous model; it looks like a closed book. The bottom of the device is one side of the "book" and the top is the door for the two drive bays. The door can be pressed to open and the hard drives can then be pulled out to be replaced easily, without any tools.
On the front, the drive has a large vertical white light that shows the status of the drive. On the back, the drive has an array of peripheral ports including USB 2.0, FireWire 400/800, and eSATA. It comes with all cables for the above connection types, except for the eSATA. It's a little disappointing that it doesn't support USB 3.0. This is understandable, however, as the drive is made primarily for Macs, which don't currently support USB 3.0.
Also on the back, you'll find a power button that turns the drive on or off. We noticed that the drive seemed to go into sleep, or low-power, mode after being idle for about 10 minutes or so, and it would take about 2 minutes to wake up. There's no way to prevent it from doing this, unfortunately. While in sleep mode, the drive would sometimes unmount itself, and this proved to be problematic for those who sporadically need quick access to it. The drive would also take about 2 minutes to be recognized by the operating system, which is a very long time compared with other external hard drives. All this makes the drive seem "buggy" at times. Hopefully this will be resolved via a firmware update.
Though the hard drives are easily replaceable, as mentioned above the My Book only works with GreenPower SATA hard drives made by Western Digital, and comes preloaded with two of them. The review unit we received came with two at 3TB each, configured in RAID 0, offering a total storage amount of 6TB.
