Got a 15" i7 from earlier this year and want to upgrade to SSD. This is my only computer and trying to be used for lots of photoshop and hopefully other intensive programs that would be relevant in the world of photography. I'm thinking just getting a simple 80-120GB SSD for the computer to run everything and then store everything on external HDDs. I just got a 1TB OWC Mercury on the Go as my external and now looking for what the best thing to run the comp is. I was going to simply get an OWC ~120 SSD, but figure I should ask everyone here for suggestions. I am not very knowledgeable about non basic stuff like RAID and so forth, and don't read tech lingo very well, but I am a quick learner and not opposed to having to learn some more things if it will benefit me. I was reading some posts about dualing up the SSD in the optical drive and setting up a RAID. I can see how easy it is to physically set this up, but I don't know about setting up RAID. Though I will be reading other sources to learn about things relevant to my situation while I'll be waiting on responses. Bascially... Whats the best way to upgrade my situation. Already got the 15" 17 with the 500GB inside a 1TB OWC external. I want to just upgrade the comp so it runs everything faster and just store stuff on the slow externals. Please, open to all suggestions.
