> I haven't seen any studies on the BluRays, but I've seen several blog posts that I found pretty convincing. This is the only one I could find in three minutes of googling, but I'm really quite sure I've seen others: http://www.microscopy-uk.org.uk/mag/indexmag.html?http://www.microscopy-uk.org.uk/mag/artsep16/mol-mdisc-review.html http://www.microscopy-uk.org.uk/mag/indexmag.html?http://www... That's interesting. However I still have a couple questions: 1. My understanding there are significant brand-to-brand quality differences with optical disks. A better comparison might be Verbatim regular BDR vs. Verbatim M-DISC BDR than TDK regular BDR vs. M-DISC. 2. That article is from 2016, and I wonder if it holds up. From what I've read about optical disks, even were the disc was manufactured can be significant within the same brand. IIRC, back then they might have been making them in Japan, and I don't think they do that anymore.
