DW1620A DL vs. SA300 - Page 3

The BenQ DW1620A can report PI and Jitter values from burned DVD recordable/re-writable media. What's rather disappointing is that the drive cannot read the media at high speeds, since even at 8X reading speed, the real speed is around 0.5~1.3X. The scanning interval also is not 1ECC but 8ECC, dropping the accuracy of the drive, since the sample count is low.

Please note that the posted results are only valid for the specific tested BenQ DW1620A DL drive. Using other DW1620A DL drives can produce totally different results. Be aware!

#3nd Test Disc - PISum8/PIF Comparison - 8X Reading speed

The DW1620A read the disc at an extremely low speed of 0.4~0.6X. The reported PI error rates are very low, indicating a perfect disc, which is correct compared with the CATS results. The reported DC Jitter from the drive is low indicating good disc quality.
