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
