I posted a few nights ago about whether to get an imac or a mbp and decided on a 15" MBP. I was looking into the software i would be using last night and i saw that Adobe prduction suite which is what i will be using for my film editing (which is a major) needs a 7200RPM hard drive does anyone know how it runs on 5400RPM. Is it worth me saving up to get an SSD instead (if possible could someone please explain what SSD is?) I do plan on getting an external to do my editing on, but i want to use the MBP as the computer. Thank you so much for reading my noobish question!
