I've been using Photoshop for some time now, but have noticed some odd hard drive behaviour when using it on my Mac mini (but I don't remember it on my old PC). I have plenty of RAM and the scratch size is well below the amount assigned to photoshop - so there *should* be no swapping to the hard drive.
However, every time I make a change, such as toggling layer visiblilty, or moving a curve, or changing levels, there's a hard drive grind of about 0.5 seconds or so. Every single little change. It's intensely annoying and a bit of a concern, as it does impact on performance slightly. So my questions:
1) Is this normal? (can anyone else confirm it?)
2) Is it actually writing to disk, despite there being plenty of RAM?
3) Would an external scratch disk make an improvement?
Thanks!
