The problem isn't the size but the time it takes PS CS5 to crunch through the save. It's sometimes over a minute long. Sure I'm saving to an external but I'm telling you, it takes 85% as long when I save to the internal SSD.
No joke. This is bullshit.
If you look at my photostream, you see that I don't edit singles anymore. I batch edit. This means multiples (usually of 4's) of images simultaneously opened in PS. Not a big deal if they're measly little 12MP files from the D3, but when they're 31MP files from the H3DII... /sigh I'm SOL.
Yes, I know about the "uncheck build previews on save" trick. But how the hell will I know which file is which without previews? They're all just typical camera-raw file names A-something-something (H3DII files) or DSC-something-something (D3 files). Impossible to figure out what's what without previews.
I thought I needed more RAM. I really did. Instead I need PS to save faster. But I'm not really sure that's entirely a hardware issue. As I mentioned, saving uncompressed TIFs on my local SSD isn't much faster.
