I'm looking to get an external hard drive for my macbook pro. It seems that I'm quickly losing hard drive space. A big part of the problem is my itunes library, but the other huge part of the problem is that I do a lot of music recording. I'm wondering if the MyBook would be a good external hard drive to record to and then access music samples from? I couldn't find anything on the website about how fast it is? Is it 7200rpm? Post your reviews of the MyBook external hard drives please. I was specifically looking at this one here. Thanks!
