CD-RW reading speed

hi,

In my LTR40125S with ZS0N (or ZS0P) firmware I cannot read CD-rw at 48X… the drive autolimits the speed at 40X…
OK I think this is normal… but in other newer liteons is the rw reading speed limited too?
does they have a better hardware-> faster speed?

The 52246S drive also reads RW discs (all of them) at 40x CAV.
