I have a 2 bay enclosure from OWC. Nice unit but not very quiet and it doesn't sleep. Looking for a 2 to 4 bay external that's quiet and will sleep when not in use. I stream all my photos and movies to my older apple tv. Was thinking of plugging it in my airport extreme. Anyone doing this? Is there a way to password protect the entire disk if I do hook it to the airport? Was looking at OWC's 4 bay inclosure but don't know if it's quiet. Plus it's raid only (from what I have read) and don't need raid, just JBOD. Suggestions?
