Tested: How Many Times Can a DVD±RW Be Rewritten? Methodology and Results(goughlui.com)

IIRC, the issue was never how often the DVD-R/W could be rewritten.

The issue was the fact that everybody assumed that the DVD-R/W discs had roughly the same lifetime as actual DVDs and that turned out to be woefully incorrect.

The quality differences between DVD-RW brands and batches were huge, with some discs barely surviving ten rewrites while others managed many more. Exposure to heat or sunlight kills them quickly, even though they were not marketed as disposable. For real archival needs, options like M-DISC, tape, or cheap SSDs are more reliable than rewritable DVDs.

People did? I thought that was common knowledge, as it also was for CDs. Not only that, compatibility with players were much worse.

Though there were times were RW discs cost as much as normal ones, and some friends of mine defaulted to buying RW even for stuff that was write once. I didn't get that, but for them the ability to, maybe, reuse the disc outweighed any reliability issues.

I didn’t know there was a rewritable dvd format. My dad had a bunch of dvds, I used to love sneaking one off to play on my computer when I was a kid, since he stopped noticing when he got into bluray

There was actually only a short period of time when only write-once DVDs existed. By 2005 just about any computer DVD drive you could buy supported all combinations of {CD,DVD}±{R,RW} that existed. Blank RW disks were, of course, more expensive than R's, though.

Yes, they were present and not much expensive than standard ones. However, the issue was that they encountered problems/data loss after few rewrites.

Except that according TFA they can actually last thousands of rewrite cycles.

Indeed, I posted it because my experience was different, perhaps due to my DVD writer or my settings. After 10- 15 rewrites, I almost always encountered issues

Looks like a stale article from 2006.

Really astounding dedication! And to be honest, I'm really surprised that DC Erase actually revived discs. Maybe the next step is to pick one disc, and keep using DC Erase, and see when it absolutely and totally fails?

When I was a kid I read that you can format DVD-RW in a way that makes Windows see it as a normal filesystem. The next step was "can you install a video game onto a disc?" and the answer was "nope, you cannot, at least not Lego Star Wars".

Also, there was a strange phenomenon that I'd love to see someone explain. I burned The Sims 2 onto CDs. The game worked. After some time the disc would fail at a file called voice1.package. I burned a second disc, which would again last some time, and then fail at the same exact file. I went through many discs, each one displaying the same behavior.
