Well, I finally pulled the trigger this morning on ordering a fully loaded 27" i7, m395x, 512ssd iMac. I was going to make the switch from pc to mac last year, but held off based on purported heat issues and the retina display being in it's first year. I kept debating again this year, but figured I will always be waiting if I keep waiting for the latest and greatest. I didn't want a spinning drive in my iMac, so I went with the SSD over the fusion. Not really interested in setting up as a RAID. I would like to add an external drive 1-2TB for media and files, and a second external 3-4tb for a time machine backup. It would be nice to do some type of enclosure so I only had 1 usb cable. In the past I have had trouble putting drives on a usb hub. Is that still the case with putting a drive on a usb hub? Does anyone have any recommendations on a setup? Suppose maybe there will be some SSD's on sale Black Friday for the non backup drive. Would love to get your inputs. Thanks.
