I'd like to setup a shared RAID 1 drive on my network. There seem to be 2 options: 1. Buy an external drive enclosure with 2 disks and hardware RAID support. 2. Buy 2 external drives and set them up as RAID 1 in OSX. Number 2 seems to be cheaper (especially if it works with USB2 drives) but is there any big advantage going with number 1? This setup would probably be conneced to a Mac Mini serving as a general media store.
