I’ve been playing with a new Sony DRU-820A last night, and here are some of the results.
I will post quality scans of several media types, comparing identical media (from the same pack, or in a few cases, another pack purchased at the same time) in DRU-820A and another burner or two, with selection determined in most cases by my own burning habits.
Keep in mind that this is not a complete test where each disc is a full 4.37 GB. Some of these are test burns, others are ISO burns. Most, but not all are burns at the rated speed of each media. All were done with CD-DVD speed.
All discs were scanned with the same drive, a BenQ DW1620, at the same speed (8x), in order to eliminate scanning differences.
I will give my overall opinion of this drive at the end, but you are welcome to draw your own conclusions.
Now, with all this out of the way, here are the quality scans, in alphabetical order by media code.
