The quality measurements for all written media are very good. No media reported C2 errors while the C1 error levels are at very acceptable levels, at all written speeds and with all media. Again, we need to mention that the maximum supported speed of the BenQ DW822A for CD-R writing is 24x, a speed which is much lower in comparison to competing drives. Despite this, for those who are not interested in fast writing speeds, the BenQ proved to be a very high quality CD-R writer.
