Collections of digital photos need to be kept alive by being copied to a new medium every now and then. You can't just copy once and forget. 100 years from now, nobody will be able to read them, even if the data is well preserved.

So storing on DVDs is downright stupid because it gets so tedious to keep the collection alive when it is spread across several DVDs.

I agree that transfer to new mediums will be necessary but many people grossly exaggerate about the lifespans of storage mediums. Optical discs have now been around for over 30 years. I suspect they will still be around at least for another 20 years, possibly much longer since there will already be so much data already stored on that media.

You need a medium which is large enough to hold all your keeper photos and other important digital information, so everything can be easily backed up, shared - and moved to a new medium when that time arises.

by far the most archival storage medium currently is MDisc DVD and MDisc Blu-Ray. the later especially is perfectly suited for most people's photo storage needs. I believe American government agencies are also using MDisc. It's what I use now.

Right now, harddisks is an example of such a medium. Cloud storage is another, though less tangible and secure in some ways.

hard disks lose data over the years just sitting unused. I think they are only good for short trm storage, and with at least one backup.
