Well, I actually have a few questions. I've searched around online looking for a large hard drive to put into an external case. My range for the size is 200-250 GB. My first big question is: What's the difference between the Maxtor DiamondMax 9 Plus and the DiamondMax 10 Plus? I assume there is a difference between the cache, 8 MB for the 9 plus and 16 MB for the 10 plus. So does anyone know anything about this?
