I am about ready to put my order in for the new 2012 iMac 27" Going for 3.4GHz Quad-core Intel Core i7 8GB RAM, will upgrade to 32GB via OWC. I just can't decide on which drive setup to order. I am initially thinking the 1TB Fusion setup, then disable Fusion, install OS/APPS on the 128GB Flash Drive and use the 1Tb drive for iTunes storage. Then use both, a external USB3 4TB Drive for image storage and a 256GB SSD Thunderbolt for Lightroom 4 Catalog and PS6 scratch disk. and one more USB3 4TB for backup timemachine. Will this work? Meaning disabling Fusion, creating 2 separate volumes, install Lion on the SSD, and go from there? I have nothing against Fusion, but I am still worry that if the 1TB HD dies, then so does my iMac, I have much more faith in SSD/Flash drive then a spinning HD..
