I'm trying to figure out a good setup for my needs. I think the fusion is going to be my best option due to price for internal, as I can see Apple charging an arm and a leg for a big SSD just like they do on MBP ($900 to go from a 500GB hard drive to a 512 GB SSD?!). So I'm thinking that the internal fusion drive would be best and cost effective option to keep the OS running as fast as possible as well as all of my applications and other files that get accessed often. So outside of that, I was considering an external enclosure (USB3 or thunderbolt) to put a big SSD into for my Aperture library, photoshop scratch disk, video library, etc. ($385 for a 512 SSD + $20 for an enclosure) Photoshop/Illustrator is used daily for work, Aperture is used weekly, video editing is done every few months for fun. Currently I've got 150GB of photos, 150GB of videos and the remaining 130GB I'm using is between music, work files, OS, apps, etc. I think if Apple offered the 256GB SSD option (and cheap enough) I'd consider that. Anyone think this setup would be a good option or would someone recommend a different route for all of my stuff and what I use?
