Hi, I have a 17 inch, mid 2009 macbook pro and am looking into options for using an SSD to boot my OS and applications from. Is it possible to boot from an ssd that is installed via my pci express card slot and is this recommended? I'd like to run my applications from that drive that include cs5, avid, pro tools etc. Is running 'intensive' software off of an ssd like that risky in terms of stability? On a separate note, I'm looking to upgrade my ram from 4gb to 8gb. I saw that there is OWC 8gb of ram for $50. I find it hard to believe it could be of the same quality as the ram apple sells for $400. Is it really marked up that much or is there a difference in quality. I'm willing to spend money on ram, just not $400. What would you recommend? Thanks.
