Anyone running LR4 catalog and cache on a SSD? I'm finding my LR4 is slightly sluggish when moving from 1 pic to the next. It is currently on a 7200 rpm drive. I have already render them 1:1 preview as well and have also set a side 40gb for the cache. I have 8gb of ram and a intel core 2 quad q6600. Rendering and exporting to me is acceptable but just when you start working on the develop module, I find it very slow when moving from 1 pic to the other. I want to quickly reject the ones that I do not like. The speed is roughly 2-4 seconds right now.
