I have a new MacMini and I bought a Lian Li 503 box to hold five drives. I use the drives for storing the video files I work with. The box runs USB3. The box is a very basic DAS, with five trays. But it can be very annoying with respect to sleep. Basically, the drives will go to sleep without properly ejecting themselves. Another annoying feature, is if I am uploading a large video file to FTP and it's from a drive in the box, the drives will not stay spinning and I eventually lose my upload. The only solutions that really only sort of work, are Caffeine to keep the MM awake and Jettison to eject discs on sleep. Anyways, I am getting very fed up with this unit (maybe it works better on Windows...) so I appreciate any advice on a replacement DAS that can take five drives or maybe four, at a squeeze. But it must be reliable with sleep. It could be Firewire 800, since FW seems much more reliable, just not so fast.
