Here is what I am considering along with my questions... 21.5" iMac i7 Processor 16GB RAM 256 Flash Drive for OS and Apps Some sort of External drive for data - NEED HELP HERE So my questions are... 1. What type of drive should I get for my data drive? Also if you have brand specific, including enclosures, please comment. 2. How do I setup a backup system for both the internal SSD and the external HDD data drive? Thanks!
