Western Digital My Passport Pro was announced last month on the 31st March 2014.

It is the first portable, Thunderbolt-powered dual-drive with integrated Thunderbolt cable. Because it is powered by Thunderbolt, you do not need a separate power source.

It is meant to be used with a Mac and hence it will come pre-formatted with HFS+ J. And of course, you can expect it to work with Apple Time Machine.

The internals consist of two 2.5-inch hard drives housed in a sleek aluminium enclosure and it is thoroughly shock-tested for extra durability to perform reliably when working on the go. Because it has two hard drives, you can configure it to be RAID 0, RAID 1 or JBOD.

It measures 143.4mm (length) x 88.5mm (width) x 44.2mm (height) and weighs 718g.

It is available in two sizes, the 2TB will be retailing for S$499 and the 4TB will be retailing for S$699.

On paper, Western Digital claims it can go up to 233MB/s for both read and write speed. I tested the speed using Blackmagic Disk Speed Test and I got pretty close. For RAID 0, I got about 198.6MB/s for write and 205.8MB/s for read. For RAID 1, I got 100.4MB/s for write and 103.3MB/s for read. In contract with USB 3.0 on my Western Digital My Passport Essential SE, I got about 58MB/s for both read and write.
