Hi, I'm finally going to upgrade my 2009 24imac to the new retina iMacs. I would appreciate some advice about drives. I primarily use Aperture and Final Cut, and have about about 800Gb of photos and 800gb of videos. I currently have the photos on the internal drive, and videos on the external and a NAS to back-up. If I get the 1GB SSD I will still have to split my data across the internal and external drive, which gets messy with management and back-ups. Particularly as I am at the point where I can't put all photos or all videos on the SSD as both are close to the 1 TB limit, and setting up separate libraries complicates things. If I get the 3TB Fusion I can have all the photos and videos on the internal. Will this give me faster access to them than having them on an external? I'd love to get a 3TB SSD but there's no option. Any advice? Can anyone see a way that I could utilise the 1TB SSD effectively? (I'm not concerned with the cost difference) thanks!
