I read diglloyd's MP review, and wound up reading for three hours about MBP usage with scratch disks. I have used Photoshop for 5 years, and I have never heard of this. I understand the process basically, and correct me if I am wrong. Photoshop opens a file, and needs space or "room" on your hard drive(s) to work. With a scratch disk you use a second totally empty drive as this "empty" space or "room". This speeds up photoshop usage with larger files. I will be buying a MBP in august ish of this year for school. (Graphic design major). I am quite familiar with computers, building them and what not, but this process is very new to me. What setup do you need for this? I want great performance, on a decent budget. After reading some very great articles from Digloyd I have learned quite a bit. However I am unsure about the process.I think you just need a MBP with fast internal hdd, 6 or 8 gb of ram, an esata card for the express slot, and 1-2 "fast drives". This setup will be used at my desk, and then unplugged for me to tote my laptop around for work and class. Edit: Machine will be used for photoshop, illustrator, frequent dvd ripping (like 3-10 a week). Also a lot of generic things; internet, itunes and the like. Questions 1. Is this setup correct? 2. Do you use desktop or laptop drives? 3. Is size important with the drives? 4. If desktop 7200 or 10000 rpm? 5. Or solid state? 6. What do you use for a scratch disk? 7. Also 4gb 6gb or 8gb? I would think more is better for ram, but I may see diminishing returns with 6 or 8 having to buy a 4gb dimm of ddr3 Thanks. Any roadblocks or benefits of this setups would be greatly appreciated as well.
