Perhaps I should have been supportive, however it was just to much fun to flame you :). Anyway, does the following link look like your RiData media?
If so - the the media code your looking for is RitekR04, which has me a bit confused since in Dee’s explanation of the her mods to the firmware, that one shows up as 2.4x in the stock 2.18 firmware with her mods allowing upto 12x. So I am not quite sure what Meritline and Ridata are refering to. Maybe some of the Moderators know more about this. I myself have never burned anything with that media code.
As for time saving with increasing burn speeds, its always a case of diminishing return. Since the max speeds that a drive attain are reached at successively later points in the burn (typically, I think i have seen some clv burns out there that have reached twelve and the drop back down?), then the amount of time you save moving up to the next becomes less and less. Thus just because you double your speed, don’t expect your burn time to be cut in half. It just isn’t a linear relationship.
And as for speed of the burns, that really isn’t of prime importance, as others have pointed out. It is about maintaining the best burn that you find acceptable at the highest speed possible. The higher error rates in your burn will probably damage the compatibility, playback, and longevity of your burns.
Also remember that your in the NEC forum, so insulting the drive is not likely to win you much in the way of a sympathetic ear. Also take a look at the number of people hanging out in the NEC forum relative to the other manufacturers. It definitly appears to be the most popular recording hardware forum at freaks (and I think the support that Quickee, Liggy and Dee as well as the rest of the Mods on the NEC forum have alot to do with that ).
Now if your looking for the best firmware for your NEDC, then travel no further than the two links below. Both Quickee and Dee are extremely responive and will go out of their way to try to help you out and give advice. Which one you end up using will probably just be a matter of personal preference.
One last thing, look at the results other people get from their burns in these threads, that way you will generally know what to expect. Then if you have problems, do some quality scans so that the folks in the forum can help out.

God, I wrote to much. And please disregard all spelling and grammar mistakes. Being that I went through the public school system in the US, english is pretty much my second language (nor did I proof read any of it!).
