I still remember the days of owning a 500MB HDD and thinking this was amazing, then the days of 8GB - 20GB HDDs were out when I was into the LAN scene and now we're looking at 3-4TB HDDs in a single drive, the storage industry really is just insane.

Well, WD are now offering their My Book Thunderbolt Duo 8TB drive, with 8TB in a single external storage option. On top of 8TB in a single package, you're also going to get the amazing Thunderbolt technology for some truly mind-blowing transfer speeds. WD even includes a Thunderbolt cable in the box, which is on one hand great to see, but I would expect a Thunderbolt cable to be in the box when selling me a product with Thunderbolt in the name.

The storage giant also offers the My Book 4TB storage drive which sports USB 3.0. WD's entry into 8TB is the first time the company has crossed the 8TB mark with a My Book device. WD's My Book Thunderbolt Duo 8TB is available in select US retailers, or on their online store for $849.99 MSRP. The My Book 4TB drive is available for $249.99.
