When OWC released the kit for the late 2012 27 inch iMac i upgraded the HD to a 2tb hybrid hard drive. Looking back, i don't know why i didn't go with a bigger drive. Last week i ordered the OWC blade ssd (480GB) and i was thinking i may want to swap out the hard drive for something larger. I really don't want to get into it a third time, so adding the ssd and a bigger drive and being done. I have no issue with space, so part of me is ok with the current setup. Any thoughts?
