I have a MacBook Pro (MacBookPro6,1) that came with a 500GB Seagate 7200rpm disk (ST9500420ASG) Having already maxed out the RAM to 8GB now I want to: 1. optimize drives for performance 2. add more capacity 3. a backup plan I decided to ditch the optical drive and bought the OWC Data Doubler and the 1TB WD Scorpio Blue 5400rpm disk (WD10JPVT) Now I start to realize that the important thing is to separate the "BOOT" drive from the "MEDIA" drive. To make the Boot drive fast I will have to replace the 500GB Seagate disk with an SSD drive. I was thinking the 128GB Crucial m4 SSD (CT128M4SSD2) So in my MBP I will have: "BOOT" 128GB SSD + "MEDIA" 1TB WD I do photography and video. I could maybe partition the "MEDIA" drive into 2x 500GB "PHOTOS" + "VIDEOS" As backup I have 3 disks: - 500GB Seagate 7200rpm - original MBP disk - 500GB Samsung 5400rpm I use as backup until now - 160GB Seagate 7200rpm disk from an older MBP (maybe use this to backup the SSD Boot disk?) I connect these drives via Firewire 800 in an enclosure. Later could decide to get a 2TB Time Capsule to do the backups automatically and wireless. -- What do you think? Is this a good plan? Should I partition the MEDIA drive? I think the "VIDEOS" part will eventually become bigger than the "PHOTOS".. Anything performance wise I should be aware of? For example I have been doing some reading about moving the Home Folder and the Sleepimage out of the Boot drive. Do I have to make a special partition for this on my "MEDIA" drive? I want to optimize this machine for Adobe CS6 Apps like Lightroom, Photoshop, After Effects and Premiere Pro. A lot of these Apps write cache files in username/Library/Application Support/Adobe folders. Do I need a "scratch disk" as well? Where could I make it and how big? A disk for cache needs to be fast.. but I guess the 1TB WD 5400rpm is not ideal.. Should I get a bigger SD drive than?
