Does it matter what speed CDRs are recorded at?
As technology has progressed CD burners have gotten faster and faster. Burning at faster speeds will not cause errors or sub-par quality CD’s provided that you are not recording disk-to-disk and that the blank CDR’s you are using are compatible with your burning speed. This is normally listed on the box the CDR’s come in their jewel case inserts. Most CDR’s are compatible with up to 8x burning, but it’s always a good idea to check first.
