Then when the newer Release 2 firmware was flashed in, this changed the write speed to the card, too, even though the formatting was the same. So, it is still uncertain to me what "optimal" means, e.g. best read/write speed on average, best file integrity, security, or what?
Are you sure that is the card write speed? I was reading the thread back then and I always took it to mean those numbers were the bit rate of the video which is something entirely different than card write speed. If those posts really were talking about card write speed then you are right. But if it was video bit rate, that would all depend on how the video encoder decided to encode the video before writing it to the card (a decision that seemed to depend on how the card was formatted, not the card's write speed).
