I use four external drives with my MacBook Pro for my iTunes library, backup, and large file storage. Right now, the drives are in external enclosures and are connected via USB. This situation is getting difficult to manage: The drives are sometimes accidentally disconnected (by a loose connection), and I often want to unteather myself from cables. This has led me to explore ditching the cable altogether. Here are my goals: 1. Avoid mounting/unmounting the drives when I move the MacBook from my office to another location in the house. 2. Not sacrifice too much speed. Would an NAS setup work for my purposes? If so, can you recommend a product? What kinds of speeds can I expect? This is for casual home use. I don't need a professional-grade system and don't want to spend professional amounts of money. What about hooking up the drives to an AirPort Extreme router? If this is an option, would I be able to use a hub to use four drives at once? And what kind of speeds can I expect here? I have a 2007-vintage Airport Extreme that I can get my hands on (http://amzn.com/B000UZCR56) but won't be too disappointed if I'd need to buy a newer model. If there are any other options you'd suggest, I'm open to them. Thanks!
