WORM vs. rewritable media read speeds

[dbminter]

Are there different read speeds for WORM media vs. their rewritable counterparts?  I guess it's down to the rated read rate for a particular media dependent on the drive manufacturer.  But, let's say, a drive is rated for 16x DVD-R/ROM read speed.  Does this mean a read speed for a 4x DVD-RW will also be 16x?  Probably not, but I don't know, hence why I'm asking. 

 

 

Thanks!

Yes, the drive specs will detail the speeds at which it can read different media types.
