I finally tested PP5.5 in my 2008 Macbook Pro Dual Core 2.4Ghz, 6GB, 500GB 7200 and unless I'm doing something wrong, my 700MB R3D test file doesn't really play back, even at 10% size. The cursor moves across the timeline but the image struggles to keep up.
I'm not clear on what my next step should be. I've considered installing an SSD for the applications only, and running files from an external drive. I've inferred from other posts that one typically sets one external drive as the source and another as the scratch disk, with both using the fastest connection available. For me, this would be using either Firewire 800 and/or an eSata adapter in the expresscard slot and two external 7200rpm drives.
Do I spend money testing this proposition or just get another computer (which will also have to be upgraded)? Will even a new Macbook Pro keep up? Thanks in advance.
