I couldn't really find a place to ask this and since most video professionals use RAID arrays I figured this would be an OK place to ask. I have a 4 bay RAID5 enclosure that has 1.5TB drives in it. Can I take one drive out, and swap in a 2GB? Let the RAID rebuild and then do it with the next drive and so on until all 4 are swapped out? Once all 4 are swapped would the RAID be recognized as 6TB instead of 4.5TB? It seems like this would work, but I don't want to go mucking around with something potentially dangerous to my storage as all the media in this enclosure is vitally important to my business. Thanks!
