I'm looking for a good way to store 10 to 20 TBs of data. It needs to be readily accessible, but it doesn't need to be extremely fast. A normal usb 2 connection is fine, as well as firewire or esata or ethernet. I do transfer large files, but there is no urgent need for them to be lightening quick. As it stands now, I have several external drives just hooked up to my computer. I'd like to avoid continuing that method. I want only one volume to show up on my mac. It doesn't have to be through raid striping, though I don't really know of another way; maybe just a container volume that has all the drives in it? It'd be sort of nice if I could access these files from several computers over my local network, though not absolutely necessary. It needs to be fairly inexpensive. I need at least two of these systems to ensure I don't lose the data, so cost is doubly a factor. Part of the reason I've got so many singular external drives is because they're cheap (like $70 a TB), and I'd like to stay around that general range. So total cost should not exceed $100 per TB at most. Finally, I'd like to be able to turn it off by simply ejecting the volume and hitting the power switch. No shutting down, or unplugging, or whatever else. I've been looking at the Drobopro 8 bay storage array, and it seems near perfect, but it's just so expensive (~$2200 for Drobo + 16TB of HDDs)(~$137 per TB). Other thoughts include the Stardom Sohotank ST8, but from what I can tell about it is that it is a simple enclosure. Any advise or ideas would be welcome. Thanks in advance.
