Title says it all. I recently purchased a top of the line 2012 cMBP from the refurbished section and I'm having second thoughts about the purchase. For 500-700 dollars more I can have the newest Haswell rMBP with the 1TB solid state drive and 16GB of ram. It would be nice to have 2TB of space with my 512GB SSD and the Toshiba 1.5TB drive from OWC installed, but I'm starting to think that utilizing my Synology NAS (712+) to take over the bulk of that file storage would be more efficient. I've also heard (and probably experienced) that having a second drive in the optical bay causes the battery life to be not as efficient? My 2010 cMBP has been modified since pretty much day one, so I wouldn't know much difference. I guess what I'm looking for is stories from anyone else who's had this experience or anyone that has any advice for someone who's possibly transitioning from a modified cMBP to a rMBP.
