Hey All I just bought a 256gb ssd to put in my early 2008 mbp (the 500gb hitachi 7200 crapped out after three years). I am looking to also put in a 500gb or bigger second hard drive in an optibay enclosure. Speed is not a huge issue, I am mainly looking for something to hold my 100gig iTunes folder and other files. Would like it to be quiet, cooler, and have a good life span. Needed help deciding on a new hard drive for the second bay. Anyone got any recommendations? I had been looking at another hitachi like I had, Scorpio black 750, and Seagate momentus 1tb but am open to suggestions. Thanks all!!
