    I have been noticing considerable lag on my 2010 15" MBP (4GB ram) whilst using Photoshop Cs5.

    I heard from my friend that if I were to use an external drive as a scratch disk, it would help.

    I was wondering if this is true, and if so, what are the recommended external HDD?

    Why not just get more RAM? Its getting cheaper and cheaper you could probably find it for around $80.... And that will be better than a scratch disk.

    RAM or set % of memory used smaller.

    What are you trying to work on? How big are the files?
