Hiya guys, right I have a MBP 15" i5, it's got a 320GB HDD but it's filling up fast! Too fast! I tend to have alot of media especially large HD films shows etc so I was thinking of upgrading too a 1tb HDD. Does anyone have any recommendations for a replacement drive? Any real difference in the write speeds? Also is it easy to fit myself? Cheaper price is better but I'd rather pay a little more if I meant I was getting a much higher quality product! Many thanks in advance! Sorry just realised I put MBA in the title! Mistake it's a MBP!
