I'm thinking about picking up the high end 15" Macbook Pro sometime within the next two weeks. I want to upgrade the storage on it to a 256GB SSD, mind you, I'm doing this through the Japanese online store so it'll set me back 45,000 yen for a 256GB SSD upgrade. I could do it through Apple or I could go out and buy a, let's say, Crucial C300 for about 46,000 yen and do the upgrade myself. The prices are just about the same so I was wondering if anyone knows the model of the SSDs Apple uses so I can see if the read/write speeds are just as good as the C300 I might pick up. Thanks!
