What's the difference between "fast defect repair" and "slow defect repair"?
So far I've understood that:
- if media has defect repair (DVD-RAM, BD-RE) it will go half the nominal speed.
- if you enable stream i/o somehow the speed you get is the nominal one
- AFAIK stream i/o will not disable defect repair, so this protection
will still be active
- some firmware/media may not accept stream i/o
So, if firmware/media accept stream i/o, what would be a good reason
not to use it?
