I have a huge iTunes library which I store on my Time Capsule. This works pretty well, but the Time Capsule is a bit slow to wake up from sleep, and copying or retrieving files can be a bit sluggish. I'm wondering if the new TC performs better/faster for local files; anyone who has one can help me out? Or, can anyone point to any reviews of the new units? I've been looking but haven't been able to find any yet.
