I went this route a few years ago and almost immediately went back to separates. A few things to consider: Typically the multi-drive enclosure have fans. Mine, which was a brand mentioned in prior comments, was noisy. It's a lot simpler grabbing a single drive and take it wherever. Redundancy. I have well over 10 terrabytes of drive space and, over the years have had about 6 drives go down. 5 were failures with the enclosures (all were from a brand mentioned in prior comments). Flexibility. Singles are easier to stack, flip on their sides and package in available space. Multiway drives not only tend to have larger footprints but are a lot less flexible in space utilization. The downside of singles are all the cables and power supplies that are get piled in a heap and tangled up with eachother.
