Any tips for speeding up Lightroom4 with D800 NEF's

I've been planning a system upgrade and have been thinking of a fast SSD to process (LR4, PS CS6, Unified Color Expose) large files (up to 1.7GB stiched, with layers, etc.) and then put the files onto HDDs as large volume SSD storage is still not affordable.

I'm curious, have you found an efficient way to work in LR, open files to PS, save back to LR, and then eventually move them to a HDD for longer term storage?

As I've been thinking about it, this seems like it will be fairly manual at the end of processing any given set of images.

Your approach/strategy on this would be helpful!
