S223 - Benchmark read slow?

Most of the DVD i burned with my other burner(Sony) is showing average read speed of around 9X-10X. But when i burn with same media with same write speed, with my new Samsung S223, i am getting slow average read speeds…



So what am i missing by getting slow read speeds?

Also, the new samsung S223 burner of mine doesnt support disk quality scan as well… any relaible solutions
