Many of us may have liked the prospect of Western Digital's My Book Thunderbolt Duo, but there's no doubt some of us who discovered that even 6TB just wouldn't cut it. If that digital pack rat mentality describes you, the solution is here: the company has taken advantage of larger 4TB hard disks to stuff a total 8TB of storage into the Duo's enclosure. The extra capacity hikes the price to $850, although the company notes that it's including the often expensive Thunderbolt cable to avoid any surprise trips to the store. Those without the ports or budget for the Duo can still reap some of the benefits through an updated, 4TB version of the regular My Book that hums along on USB 3.0 at a more reasonable $250 price. Either of the new drives should be lurking in stores if you're hurting for space as we write this.
