Western Digital 6TB External Data Storage
It was Western Digital who made the first 3 TB internal hard drives, Western Digital Caviar Green. For enthusiasts and media vampires 3TB is not nearly enough for even a small media library. HD movie rips swallow 3TB in just a few weeks and for some people even few days. Regular 1080p BRrips take 8 to 20 GB space and some even copy the BR contents to their hard drives to minimize BR drive usage. Contents may even hit 80GB from a single BR so you do the math.
Now Western Digital offers 6 TB external media storage made of 2 disks, with possibility to create different kinds of RAID missives. My Book Studio Edition 2 Device has 3 different connectivity options. Standard USB 2.0, FireWire 800/400, and very popular now days eSATA (external SATA hard drive) which has a lot faster data transfer then regular USB 2.0 and even FireWire. Even single one of these devices will considerably increase your library capacity.
