A few weeks ago I hooked up 2Tb of external storage (WD HDD and Thermaltake enclosure) for my HR24. As I already only have 40% left, I'm wondering if I can expand my storage further without buying another 2Tb drive and enclosure and going thru the powerdown, swap, and bootup routine. Can a RAID enclosure with multiple drives be utilized, using the RAID controller to switch between the drives without going thru the old swap routine? In short, what are the alternatives to having to catalogue a collection of 2Tb drives?
