I have never lost data from well cared TDK and Verbatim disks. TDK even had scratch-proof hardened DVDs. For extremely important data, I’d burn three copies enhanced with dvdisaster error correction data. I recently moved these disks to a distributed/backed up storage system since I’m low on physical space. All disks read at full speed with no hiccups. Another alternative is M-Discs if you can find them.
