To minimise drive wear due to audio extraction: reduce speed or time?

when i  Extracts audio CDs by EAC, in Which way the burner less wear out?

1.when i Increase the speed of extrication (by EAC)  and thereby reduce the extrication time?

2.when i Reduce the speed of the extrication (by EAC) and thereby increase the extrication time but use
But uses less laser (if any)?


-this is  makes any difference at all?

3.there is a recommended  extrication speed  that CD-R's seem to perform best?

I don't know, but I get the feeling the drive is "working harder" at higher speeds.  I wouldn't worry about the laser wearing out.  There are plastic mechancial moving parts that are likely to wear-out first.

And, with drives starting at $20 or $30 USD, it's no big deal when one dies.  (Blu-Ray drives are a bit more expensive at this time.)  A LOT of different things can go wrong with a computer, and a dead CD/DVD drive is one of the cheapest & easiest things to repair...

With CDs in good condition, most drives can extract with 100% accuracy at full speed. 

When it comes to burning, slower speeds might be better, especially with DVDs...  Someone had taken an electron-microscope image of DVDs burned at different speeds, and the "pits" burned at maximum speed were sort-of blurry.  (I don't know if this experiment is repeatable, or if newer/different drives show different results.)

This is a very old topic. Minimum read errors (by actual read tests) occurs at a writing speed that is dependent on both the media and the drive. The same media may require a different speed on a different drive to achieve optimum results. Likewise, different media on any given drive will produce more or fewer errors at any one given writing speed.

The most frequent best speed used to be 1X, then 8X, now generally higher (for CD-R). I don’t believe 1X media is made anymore. Errors are higher when writing below the optimum speed.

I got best results with my several favorite media at 24X, but results were very close at anywhere from 8X to 32X. Eventually, with wear on the drive (I suppose) some media that once did very well at 24X would not write at all above 8X, while other manufacturer’s blanks continued to work well at 24X. The range is smaller for DVD but the principal is the same.

I have yet to have any optical drive fail on me. Just burn and rip as fast as you can.
