The My Book Studio is Western Digital's Mac-focused range. Unlike its single drive cousin , it's not encased in metal, but rather silver spray-painted plastic. The Studio Edition II is rather sensibly named, in that it contains two hard drives, sorting it out for a maximum capacity of 6TB.
User serviceable drives; Great sequential FireWire 800 performance; RAID 1 or 0 available
Not great on the random speeds; we've seen better eSATA performance; Lid is a pain to close
