I have heard a few complaints about the HP's at the higher end. No personal experience, but have heard more than one complaint from more than one person. I would spend the extra $50 for the often opined best drive, and the burn proof which you will not get with the HP. Burn proof becomes more important with the faster drives. Unless you have a super fast computer, super fast HD, and super fast (sustainable) reader to on the fly copy, you will coaster alot more without the burn proof.
Just my $.02
