Plextor drives 'advance test'

i’m gonna buy 1 or 2 new dvd-rw drives and i check example here cd-freaks them quality to make backups my games and so.

when i check drives for that quality i see that another else drives cd-freaks test backup value for many games,several more than plextor and they are also old revision,why this?

example newest plextor,only 5 ‘old’ games tested that quality?? another else drives almoust 10 ones…

can cd-freaks or some1 explane that??

i hope they test tplextor drives same games that example NEC drives,tx
