Confused by all the various permutations of Western Digital's My Book line of external drives yet? No? Well, go ahead and add the My Book Studio Edition II to your stack of flashcards, Mr. Smart Face. Just like the previous 2TB My Book products, you're getting two RAID 0 drives in a quad-interface external case, only this time it's the updated My Book Studio design. WD's also gone and upgraded the drives themselves to GreenPower units, which run cooler and use less power, and Mac users will be pleased to know that everything comes HFS+ formatted. Got that? Expect a quiz in the near future. Available now, we're told, at $349 for 1TB and $599 for 2TB.
