I love this and I love seeing that it's from 2026 and someone still took the time to do all this testing- it must have been seriously involved because even at 6x it takes a while to fill up a DVD, and then to repeat that hundreds of times on several discs would be an eternity.
I haven't used a DVD+-RW in several years, as wireless file transfer over networks and flash drives handle pretty much all of my needs now, but I sure used the heck out of my DVD writer when I had it. I had no idea these discs could go hundreds of writes before failure, I always got paranoid about reliability and probably never went above 20 writes on a disc.
Edit: at the end of the post the author says, "that’s about 4020 hours across two drives, 5248 burns and both drives are still seemingly operating just fine." What a colossal amount of time.
I wrote an article in a similar vein some years ago that might interest you too:

Ye, having experienced the "joys" of rewriteable CDs, I completely skipped the DVD RWs, expecting more of the same. Guess it wasn't, but then again, thumb drives became a thing.
