I have used traditional 5400 RPM drives for a while now, but have heard really good stuff about SSD's. I would love to try one, but have some dbouts about it. I only really use my Mac for general computing stuff, so i'm not fussed about having lots of storage. This is what I want: http://www.amazon.co.uk/Kingston-V1...1_1?s=computers&ie=UTF8&qid=1312847047&sr=1-1 Is this a good drive? 1. Is it possible to run Windows on an external USB hard drive? I'm not too fussed about this, as I don't run windows games very often, but would be nice to be able to do (Because obviously a 64GB SSD is a bit small to put two OS's onto.) 2. Are these SSD drives as fast as the ones Apple have built into the macbook air? What is the difference between the two? 3. Most important; is it worth it? What sort of speed boosts do you get?
