Hey guys! I just upgraded my early 2011 macbook pro with the Seagate Momentus XT 750gb ... and it performs very well. I grabbed it when Newegg had a deal on it. The only complaints I have is that I can actually feel and hear the drive now versus my stock 7200rpm 500gb drive so I'm a little peeved at that. I'm considering putting back my old drive and returning this one but I really like how it performs. The reason why I went with a hybrid drive was that I needed at least 250gb of space on my laptop and cannot afford an ssd at this time. This is merely a middle point for now while waiting for the ssd prices to come down. If anyone is considering upgrading with this drive, I can say that the performance is better then traditional hard drives but (of course) not as good as ssd's ... only if you don't mind the slight hum and vibrations ... I can answer any questions if you guys have any and would like your opinion about returning this drive or not. Thank you!
