I had an HDD failure today and it pushed me over the edge. I've started shopping and reading reviews on RAID enclosures...any recommendations? I'm looking for a two bay enclosure for RAID 1. FireWire + USB would be ideal, but in order to keep costs down I may just go with USB. Cost IS an issue unfortunately. I'm looking for something at the cheaper end of the spectrum. Also, is there any complete off-the-shelf unit anyone thinks would be a good buy? Thanks to all in advance!
