These Thunderbolt Duo drives can be configured in RAID 1 but the big payoff is RAID 0, which provides speeds up to 300MB/s. You can also read my first impressions of the WD My Book Thunderbolt Duo drives with real world speed tests.
We’ve been waiting a long time for this one folks – an actual, shipping Thunderbolt external hard drive for mere mortals.
Western Digital has announced pricing and that it is now shipping 4TB and 6TB versions of its My Book Thunderbolt Duo external hard drives. I first looked at these at CES 2012, while they were still getting them ready for final production.
The dual-drive system is configurable as a RAID 0, RAID 1 or JBOD. As a RAID 0 drive, the Thunderbolt connection puts a single unit in the 280MB/s transfer range. Additionally, a daisy-chained series of 6 drives configured in RAID 0 will deliver transfer speeds up to 780MB/s.
The 4TB model is priced at $600, while the 6TB model is priced at $700. WD says it is now shipping the drives. Check B&H Photo, Amazon and WD’s online store for availability. I should have my hands on one soon and will report back as soon as I get a first look at its performance.
