Thunderbolt: Western Digital My Book VelociRaptor Duo Starts the RAID

Share

If there’s one thing you should know about Thunderbolt connectivity, it’s this: Thunderbolt transfers data fast. Very fast. 10Gbps fast. Twice that of USB 3.0’s 5Gbps speed. If you’re looking for an external hard drive that can transfer data at those speeds via dual Thunderbolt ports, includes RAID support and provides up to 2TB of storage space, the Western Digital 2TB My Book VelociRaptor Duo Thunderbolt Desktop Hard Drive delivers.

To be clear, the VelociRaptor Duo is not meant to be portable. While you could conceivably bring it with you on that rare occasion that you need to transfer massive amounts data to another computer, its primary role is to be an external backup drive. The drive also requires a wall outlet for power so you won’t be able to use it by just connecting it via Thunderbolt to your Mac computer.

With 2TB of hard drive capacity, you’ll have plenty of space to save raw video data. The dual Thunderbolt ports enable you to daisy-chain up to six other devices (five if you include the connection to your Mac computer), allowing you to be efficient and productive without the hassle of added cables.

With Thunderbolt connectivity, the VelociRaptor Duo achieves some very quick file transfers. It can transfer two thousand 5MB photos in 33 seconds, five hundred 5MB songs in 8 seconds, a 5GB standard-definition movie in 15 seconds and a 22GB high-definition movie in just 65 seconds. While your experience may vary due to file types and system configuration, this should give you an idea of how fast Thunderbolt can perform. Thunderbolt works great when working with raw video and photo files since those types of files are normally quite large. You can even use the VelociRaptor Duo as a fast 10,000 rpm boot drive to replace the slower 5400 or 7200 rpm internal hard drive of your Mac. Just make sure your Mac computer is running Mac OS X 10.6.8 or higher for compatibility purposes.

The dual hard drives also come into play when mapping out RAID configurations. The VelociRaptor Duo can be set as RAID 0 (striping) for improved performance when it comes to designing or editing graphics-intensive media files. If you prefer to be more secure with your data, you can opt for RAID 1 (mirroring) which provides another layer of security by automatically generating a duplicate copy of your data. You can even set the VelociRaptor Duo to JBOD mode (Just a Bunch Of Disks) which allows you to use each of the drives individually.

The VelociRaptor Duo is configured with Western Digital Utilities, which lets you register your drive to activate your warranty, manage RAID or JBOD modes and more. It also includes a Western Digital 3-year limited warranty.

The VelociRaptor Duo is a high-performance external hard drive that can transfer large video and photo files with 10Gbps speed. With dual Thunderbolt ports, dual 10,000 rpm hard drives and RAID 0, 1 and JBOD support, the VelociRaptor Duo is essential for all professionals working with raw video and photo files.
