I just bought a DVD±RW burner which is rated to burn dual layer DVDs at 8X speeds, however, Toast 8 says that the burner is averaging 5X per disk. Why is this? What can I do to improve the speed?
What kind of disks are you buying, and what speed are they rated for?
Was it a cheap one? Often times they list the maximum theoretical speed the drive can burn at, even if it averages much less than this. This was often the case for a lot of CR-R drives back in the day as well.
It’s a Sony DRU-830A DVD burner using Verbatim DVD+R DL disk that are rated “up to 6X speed”, but the person who sold them to me said they ought to work fine at 8X as well. Perviously, when I’ve used disks at speeds above what they were spec’d out at, they failed to burn, the drive didn’t slow down. Either way, since they’re capable of 6X speeds, why are they only burning at 5X? Thanks.
The person who told you that discs rated at 6x would work at 8x was misinformed. I have an 8x DVD writer. I thought I was getting a bargain by buying discontinued DVD packs at CompUSA. Discs rated at 1x burn at 1x, and 2x at 2x, etc. Same for CD-Rs. If the’re only rated to 40x, they won’t write at 52x. It’s part of the information the drive reads when it loads up the disc. I don’t think it’s possible to make the drive work around that limitation.

Keep in mind tech stats are often defined by the manufacturer under optimum conditions (when the moon is full, it’s not a Tuesday, only during months not containing the letter “r,” etc.).
In addition, “up to 6x speed” means just that. If it burns at 1x to 5.9x speed, it still falls within the criteria of “up to 6x speed.”
FWIW, I would be more concerned that it burns properly and the disc will play back on a variety of disc reader drives.
