HI, I am not sure if this question has been answered before but I was running out of space on my 1 tb external connected to my mac mini and was wondering what the best storage option would be. I dont have a backup of this drive so would prefer a device that would have redundant hard drives. I was looking at the Drobo and that right now is around $290 after rebate. I would prefer a device that has network capability out of the box. Do people have any suggestions or any experience with products that work especially well. Ideally I would like to expand my storage to about 4 TB. Thanks a lot for the help.
