ok, i've got a lite-on 52x24x52 cdrw and i've always used 48x memorex cd-r's and nero for my burning tool. well, i went to fry's and picked up some new cd-r's and they happen to be 52x. with the 48x i could always burn a 700mb cd (full) in about 2min 35 sec. now, with the 52x it takes me 3min 30sec - 4min. wtf?
