The thing is that it gets very confusing.
If you review a unit then i guess itÂ´s really the access time that would be intressting.
Many manufacturers however specify the Seek Time and most benchmark program measure this value.
But then ofcourse some of them use the Access time instead.
Now, either they donÂ´t know what theyÂ´re doing and just write down the forst word they can find or there is a big difference…
I hope you see my point.
So there should be a formula for calculating the access time when you have the seek time right?.. IÂ´d like that formula. [/B]
Yes and no… look at it this way…
If you have a normal cd (100% scratch free) the cd will be recognized in the given time and read flawlessly.
If the TOC of the cd is scratched , the cd could be very hard to be recognized , though files could be read almost flawlessly
If the cd is somewhere scratched , the cd could be very easily recognized , but getting files copied of it could give your reader a very hard time.
The thing is that the specs they present you usually are theoretic or ultimate numbers (“Why yes, our cd drive is 52 speed !” instead of "Our cd drive could read at 52 speed if you have a 700 mb cache and you only read this and this sector of it)
In common practice the overall usages is inserting a lot of various cd’s and rip or read them (there is a difference in ripping and reading as well !). You could check the various postings about ExactAudioCopy about that. The numbers don’t say much.
It’s far better to stick with the overall quality and in a review to test at least 20 times what the actual speed and performance is , instead of using nero cdspeed just once.
