Hi, I just recently killed my new macbook pro. (do not drink near your computer..) So I am in the market to purchase a new one and was interested in the SSD. A little about me, I'm a college student majoring in radiology. I dabble in photography, not too much, just as a hobby, and basically will use my mac for school and personal use. I was looking at a few refurbished models and was wondering which might better suit me: macbook pro 2012 with 4gb ram and 128 ssd or a pro with 8gb ram and 500 gb aerial ata drive @ 5400 rpm before these i was looking in the air, however, after talking to a couple of people they have scared me away from the idea of possibly running out of space and resorting to external memory, which i would rather not do. thanks!
