Sorry to ask this stupid question, but can you explain me what are the firmware strategy and why they are so important ? :confused:

Google is as usual your friend:

The assumption is that the newest write strat is the best for all included media. Whether this hold for all cases may be doubtful, but I assume the the companies test a lot of possibilities and choose the best one for the given media.

Some energetic people (eg. Harrie) has tried to swap strategies to obtain higher burn speed or quality, and in my experience they made the FWs even better this way. Why the companies didn’t do that is not known to me, but they may prioritize stability more than Herrie et al.
