Currently, my photo backup solution consists of making periodic backups onto an external hard drive as well as optical media. I am using JVC DVD+R discs with media code YUDEN000-T03-00, which is reputed to be very reliable, and so far I’ve had no problems with it.
However, since I shoot in raw, a single vacation could take up 10 DVDs, and I’d prefer a more compact solution if possible. I’m looking at the Panasonic BD-Rs imported from Japan with code MEI-T02-001, which performed the best in the well-known French study. But does it last as long as a Taiyo Yuden DVD?
(I’m aware that the M-DISC exists, but it’s a bit too expensive for me. I don’t need it to last 1000 years, just long enough to notice if my external drive breaks [though ideally for my entire lifetime].)
