Q: Does 2510’s DL-optimized laser hurt it’s single layer CDR and DVD writing performance?
A: If the laser is optimized, meaning factory alignment for example, for dual layer burning it does not affect it’s single layer CDR and DVD writing performance. I have both a 2500A and a 2510A with Herrie’s beta 5 firmware for the 2500A installed, you might call it a 2510A@2500A, and they write about the same on single layer disc. I have not burned any CD’s on them as yet, but my guess would be that there is no difference. I also have not burned any DL disc as I am very frugal, O.K., in my case just plain cheap. When the price goes under $2 ea, yes $2 ea, thatâ€™s when I will use them, provided that they work properly. I may actually test one or two at $5 ea, just for “proof of concept.”
I understand that the 2500A and the 2510A drives are identical with the possible exception of factory laser alignment and quality control. NEC has made public relations statements about this matter, maybe hype, maybe not, but probably mostly hype. It’s the mostly part that concerns me. It may be that almost all of the NEC-2500A drives are capable of DL burning with a firmware upgrade. At this point, lacking any inside knowledge, I don’t feel that there is sufficient data to say what percentage of 2500A drives will perform as well as the 2510A when it comes to DL burning. There may or may not be quality control and alignment issues involved. The fact that no one has reported a failure yet, doesn’t mean that there won’t be or haven’t been any. I would think people are more likely to report a success than a failure, especially an expensive one. The more successes reported however, the better it looks for the 2500A, even better for the Mad Dog Dominator, I think that’s the name, that Office Max puts on sale for $35-$40 in the USA every once in a while. For the $15 dollar difference in price, it doesn’t seem worth it to take the chance that the 2500A won’t burn DL disc properly, especially since, at this writing, the price difference is less than the price of one DL disc. To sum up in one sentence: If you want DL capabilities and don’t already own a 2500A or an equivalent, buy the 2510A.
