Thunderbolt is an interesting technology. It was introduced last year on Apple computers, and now the first PC products are available with the new connector that combines PCI-Express and DisplayPort. It lets you connect multiple peripheral devices to your computer and has extremely high transfer rates. Western Digital was one of the first manufacturers to implement Thunderbolt in its products, with its My Book Thunderbolt Duo packing two hard drives and two Thunderbolt connectors.
While it was a nice product, the performance was a bit of a letdown. Contrary to what you'd expect, WD did not employ high-speed disks and instead used slower, environmentally-friendly disks. The transfer rates were not particularly impressive, with 217.6MB/s for writing and 221.1MB/s for reading in RAID 0.
WD makes up for this with the new Western Digital My Book VelociRaptor Duo. It's a My Book equipped with two very fast 10,000 RPM 1TB disks, the fastest WD currently has. Combined with Thunderbolt, we expect to see some very interesting numbers.
The casing of the Western Digital My Book VelociRaptor Duo is virtually the same as that of the Western Digital My Book Thunderbolt, except that it has a different colour. On the front, there is an LED that lights up when the device is in use, and on the back you'll find the two Thunderbolt ports along with the plug for the power supply.
The top is a cover you can open by pressing down on it once. When you remove the screw inside, it's possible to remove the two hard drives. The disks have a capacity of 1TB each, and come in a RAID 0 configuration.
The included WD Drive Utilities let you configure the drives in RAID 0, RAID 1 or as individual drives (JBOD). This software is currently only available for Mac. A nice extra with the WD My Book VelociRaptor Duo is the Thunderbolt cable. That saves you around £40. You can read the rest of WD My Book VelociRaptor Duo preview on Hardware.info.
