LAS VEGAS--It's a teaser to say the least.
Without any ado or even a hint, Western Digital showcased at CES 2012 its first Thunderbolt-based external hard drive, called the My Book Thunderbolt Duo. This is a drive that looks exactly like the My Book Studio II with one main difference: on the back it comes with two Thunderbolt ports and no other connection types.
There's not much information about the drive, but one thing is clear: this is a dual-bay drive, meaning that it hosts two internal hard drives. These hard drives are more than likely set up in a RAID configuration.
In the sneak peek, there were four drives daisy-chained together and the demo machine showed a top performance of around 515MBps for writing and 770MBps for reading, which is as good as it gets when it comes to storage performance.
WD says that it will formally announce the My Book Thunderbolt duo at the next MacWorld Expo, which is slated to take place later this month. I guess we'll have to wait till then to learn more about the new drive and its pricing.
