I'm wondering how so many people are living with only 128gb of memory on their MBPs. I am aware of the data doubler but for some reason I feel taking out the cd drive and replacing it with a ssd would somehow corrupt the system or create problems in the future. I want a super fast ssd but the reasonable size (512gb) is almost the price of a new macbook and from what I have read they seem very unreliable. So I have seen people just dumping the 500gb 5000rpm hdd for a 128gb ssd. How do you live? I have close to a 100gb of music and movies and I feel like I'd fill it up really quick especially when it comes to pictures and such. I want the ssd for speed but the hdd for reliablity, what should I do?
