i just noticed that a shop near me stocks sata dvd-rw drives - first i've heard of them!
its probably a stupid question, but they are worth the extra $10, right?
For Extra Speed, Yes.
But personally, ive never needed any quicker than the 12x Speed im burning dvd's at...
I think right now the only real benefit of the SATA optical drives is the less obtrusive cable inside your case.
