I’ve never had a CD/DVD R last more than a year anyway, even when using expensive media and slow burn speeds. So its not exactly archival.

Right now, probably typical computer SSD disks. Anything lasting more than that usually steps in office/corporate solutions, like magnetic tape backups
Googling around, I found out there are some “archival grade gold” DVDs, and a M-DISC (available as DVD or BluRay) that claims to last “centuries”. Haven’t seem anything on scratch or dust resistance about either
