Since the quadcore MBPs came out I've been asking myself to what extent these new machines can replace a Mac Pro set up. I thought both RAM and storage were major drawbacks. Now it's known that they can support up to 16 Gb of RAM, which move their maximal potential performance yet a bit closer to MP performance. The major issue is still storage. It's been reported in other threads in this forum that the new MBP supports SATA III, but only in the main HD bay. Anything you put in an optibay will be limited to SATA II. That raise a question to someone like me, who has high hopes of using a MBP as a main editing station: - What's the ideal arrangement of scratch, media folder, and boot in a dual drive MBP? With some considerations: 1 - As boot drives Apple SSDs are apparently less of a headache. Will they be happy to sit in an optibay? 2 - Is it overkill to use a new SATA III SSD like the Vertex 3 as scratch disk? 3 - I know that if I do larger projects I'll need external storage. But I'd like to take advantage of the MBP's mobility whenever possible. Thanks in advance!
