I've had a V7 with messiah since 2002 spring, it is loud yes but works like a champion. And truly only quality discs like Verbatim DVD-R (printables especially) work at 100% speed (like in GTA games you dont get any problems streaming data). Also DVD-RW discs work great.
Ritek G04 etc have always worked but slower than originals so some videos at the inner edge of the disc will stutter and a game like GTA will load textures too late. Interestingly the samsung drive in my xbox is exactly the same, ritek is slower than verbatim. So its not just a PS2 issue.
Verbatims cost 50 cents nowadays so there is no reason to use shitty discs.
