I posted this in the SSD Buying Guide, but I have seen much activity on my question... I'm going to be getting a 512GB Crucial M4 SSD installed in my mid-2010 17" MBP. Would it make sense to put my system files and Apps on a 128GB SSD drive and all other files on the 512GB SDD? Also, would Time Machine back up both drives or would I need to use CCC for my backups? Thanks!
