Blu Ray still viable for image archives?

I know many use separate hard drives for storage. I have a few and use them and will end up with more as I go on.
Are Blu-Ray discs still viable as another media for image archiving? A physical/tangible disc stored in a good fireproof/waterproof safe so there is an alternative that won't be hit by an EMP or a major solar storm that wipes much of the electrical storage.

I know finding a new reader after an event might not be easy but could keep a portable one with drivers on the physical disc with the rest so I could use it once computers were up and running again.

Viable, or not these days?

Yes and no. Also, Blu-Ray is not susceptible to EMP and if we do have a EMP strong enough to wipe out a drive, then lost images is going to be the least of your problems. :)

As to media, regular BluRay disks do not have a very long shelf life. Some say 5 years or less. If you invest in archival media then you are safer for a lot longer. However, archival medial is more expensive. A quick peek on Amazon shows a 15 pack of archival disks runs $67. To back up one TB, you need 40 disks, or three packs. That's $201 in disks. I can buy several 1TB hard drives for the same cost.

25GB is too small to bother for me. I use 4TB hard drives.

Also, there's no such thing as fireproof. Offsite is essential.

There are the 100g disks but they are very expensive. a 5 pack runs $88 so to backup a 1tb drive, you are liking at $176. Right now on Amazon you can get a 1tb WD black passport for $46. I would rather have four passports as backup then BR disks I think.

I would think BluRay would be a pretty expensive and limited and slow option for actual archival of images.

Pick a media that will handle your requirements and encase it something that protects from what you don't want to risk. That will be more viable than some disks.

True backup is offsite. Have a mirror of everything in a cloud hosted on another side of the planet

Very best,
