I have a mbp, and 2 external HDD that primarily hold images from my photography biz. Space is filling up and I need to buy another Drive to hold this years images but I feel having three externals plugged into my mbp is getting inefficient. I know that I need to get mac pro so I can just pop'em into the the drive bays and get better speed but in the meantime I need something that will do the job until I can afford a mac pro. Are there such things as drive towers, or multi enclosures? I am not ready for RAID or anything like that, I would love to have all the drives in one box and have firewire with the option to go sata later. Or if there are better ideas I would love to hear them. Thanks!
