Here are some specs I came up with using Ritek R03 8x +R media. All three disks were burned at 8x using the same source disk.
Scanned with Benq 1620 Pro at 8x
Pioneer 108 (stock firmware)- PI Errors (44) PI Failures (21) Score (76)
Benq 1620 - PI Errors (30) PI Failures (8) Score (95)
Nec 3520 - PI Errors (40) PI failures (8) Score (95)
This is just one media that I use, but I am always a follower when it comes to buying new media for the drive that it burns better in. I buy Ritek R03's because they are affordable and they burn well.
Now with these scores, can it help pick one out to get replaced?
