Performance; RAID reliability
Western Digital’s My Book VelociRaptor Duo is all about performance. Equipped with a pair of drives that can be set up in either RAID0, RAID1 or JBOD configurations, plus a Thunderbolt interface, it aims to shift your data quickly and safely.
The hard drives aren’t the usual 7200rpm units you find in consumer storage devices. They spin at 10,000rpm for a throughput boost.
As there’s a pair of disks, they can be set up to be seen as one large disk giving a total of 2TB, a mirrored pair so that your data is automatically written to two disks for protection or as two separate disks, or JBOD. All of this can be managed using the WD Drive Utilities application that can also perform diagnostics to ensure everything is working.
The unit is quite large – about the size of three paperbacks. There are two Thunderbolt ports on the back so you can use it to daisy-chain up to seven devices. A single LED on the front indicates drive activity or, when it switches from white to amber, lets you know if the unit is overheating.
Given the emphasis Western Digital has put on speed, we were hoping for something special. We got it.
Copying files to the My Book VelociRaptor Duo produced in excess of 1.2Gbps of throughput. The return trip was slightly quicker with files returned to our MacBook Pro at 1.3Gbps. Small file transfers completed in the blink of an eye with 1GB of data moving in just a few seconds.
Macworld Australia’s buying advice:
When you check out the spec sheet it’s clear that Western Digital was trying to assemble a speed demon with the My Book VelociRaptor Duo. The company achieved that goal and has managed to deliver the reliability of RAID by using two high-end drives.
