I know there is very little preformance wise difference between 48x and 52x CD-ROM read. But how about comparing 40X to 48X or 40X to 52X?
Is there a bigger difference when compared that way?
The difference will be minimal I would be suprised if you notice a difference in speed. I use to have a 24X CDRW and it burn full 700mb CD in about 4mins, now I have a 48x CDRW and it burns a full 700mb CD just under 3mins. You would think a 48x CDRW should be twice as fast as a 24x CDRW, well its not. This is confirmed by all reviews from many sources, as speeds increases it is not proportional.
Some 40x CDROM will actually be on par with some 52x CDROM, it really depends on the maker and quality. Mind you though, the difference is so small it would be hard notice it. CDROM drive speed are not important at all nowadays. How often do we actually use the optical drive? Not often at all, and anything 24x above seems to be fast enough. All laptops are quoted at 24x and there are not many complaints about it being slow.
