As long as one never misses a back up, HDDs are fine. They're more laborious though. With the right optical disc, you can get away with just storing your discs in light-proof boxes and forgetting about them - with an HDD it's wise to copy the data over to a fresh drive at least every few years. Capacity, price and speed is the issue with optical media. With one M-disc, you get only 100GB, and the cost of the discs adds up.

- vel0city 2y agoDepends on how much data you care to store. I'm just trying to store family photos and what not, I'm not generating TB's a year. 100GB is more than enough for a whole year of important data for my family. A 25GB M-DISC BD-R, two to mail one off-site to another family member, and we've got an offline backup of our most important files with geo-redundancy. On top of the local copy and cloud storage whatever as well.
