I needed some more storage in my Early 2009 Xserve and decided to put a 5TB drive in it. Things didn't go as planned. Of course as soon as I make a video on this someone has put up a bunch of drive trays on ebay. So I have two more coming now. The external USB HDD on the server is both annoying to keep going on the server and something I would like to have back from it's permanent use here. Too bad I couldn't make that happen. I think I may have been wrong in the video and you could buy a 2TB ADM but that doesn't help me out.
