I have a black Macbook with an 80gb drive that I would like to upgrade. I've seen favorable discussion on basically all of the brands. I would like something at least 160gb. What drives would you recommend? Seagate 160 and the Toshiba 400gb seem to get a lot of discussion. I noticed that Western Digital appear to be the cheapest. Is there any downside to them? I would also like a USB 2.0 enclosure for my current drive. OWC has some but are there any others that you would recommend? Thanks.
