What about bit rot though? Some of my dvdr are no longer readable after 5 yrs, stored in very good conditions. Hdd backup, esp. with Zfs can provide very good bit rot protection.
- randartie 13y agoThese are high grade guaranteed for 30+ years. There's also 1000 year grade blu rays out there.
- polskibus 13y agoI had failures of both "archival" quality DVDs and SD cards before, just after a year or two after last backup. Do you have any links on the methodology used to measure the 30+ or 1000yr grade for a blu-ray ?
- x0054 13y agoBlu-rays are but a few years old. It's preposterous for any one to claim that they are "guaranteed" for 30 years, let alone 1,000 years. Not to mention that that guarantee most likely has an asterisk that limits damages to the cost of the original blu-ray disk in case it actually fails.
