DVD RW suggestion please?

Hi, I going to buy DVD-rw mostly for backup purpose, but which one ? I have SuSE 8.2 and I'm going to have SuSE 9.1 soon. I consider http://www.benq-eu.com/Products/DVDRewriter/index.cfm?product=412&page=specifications Does any one has any experience with it? Any suggestion which one is a good choice ? Jul.
