MLCD best CD burn speed?

[guitates]

MLCD recomends the fastest time that your burner will handle to burn CD's. Do they mean Music and/or Data OR?? I have read numerous articles that say the "glass Masters" are always burnes at 1X. I have compared 1x and 4x and I find that the 1x has Far superior sound quality. I am wondering if backing up files at 4x would be OK, or would they be "stored" in an inferior condition?

I backup to CDR (Plextor 820) with Retrospect Express. I believe it backs up at 12x. The important thing is that I use the verify option. That prompts you for the disks after backup and compares the backup to the files on disk. If there were anything wrong with the backup, it would fail that verification (which has never happened to me).

As far as audio, I'm not sure. I always burn audio CDs as 2x. I've seen opinions that 2x best, and that 1x may heat the disk up a bit too much and higher speeds maybe not enough.

As a mastering engineer, I've always found that 1X provides the best sound quality. As far as Data integrity is concerned for backing up, I would assume that one would want the best possible speed for sound quality which, in my opinion, would also be 1X.

Thanks for the input MasterJ. The next time I burn an audio CD I'll probably try 1x.

As far as backup data integrity however, if the backup verification determines that the backup is the same as the files on disk, it doesn't seem to me that you're going to improve on that. It's either right or wrong, regardless of the write speed. I wouldn't see any reason to slow down backups unless they start failing verification.
