Anyone been using "Millenniata" M-disks (Blue ray disks guaranteed to last 1000)

[ubacher]

I am partial to optical media because once written one is unlikely to erase the data.

I learned about M-disks. They are blue-ray disks with capacity of 100GB max and are supposed
to last 1000 years because of the way the data is stored. Got me interested.
One needs an M-disk capable blue-ray burner of course but one can read them on any blue ray reader.

Anyone have any experience with M-disks?

I have abandoned optical media years ago. Just read the fine print about storage conditions ...

Disks are cheap and easily replaceable before they fail.

Do you really imagine you'd be able to find a Blue Ray reader even 30 years from now?
Just make several copies on current cheap media and move to new media when it it mature and cheap (next move may be from HDD to SSD).

I see it also like Carlo.

I can remember using some "Zip"-disks ... not more of any use nowadays and hard to find a reader.

Same here.. been buying and using hard drives with redundancy now for years and can't see myself ever going back to DVD's/Tapes or the like.  LOL.. just picked up some 8TB WD Red drives for $150.... what a great time to be a photographer!

Wow, now that was a really loooong time ago!

Well, if you call 20 years "a really loooong time" ... then you are correct.

I've been using them for a few years now. Started with the first Millenniata DVDs (which does not make much sense capacity-wise) and switched to BD-Rs after they became available.

I use them only for long time storage of:
- from camera/scanner raws and generated jpegs
- for "finished" pics, after a few months, when it is not likely that further changes will occur

I always burn two discs (paranoia rules !  ) and add a digest file with MD5 checksums to the data.

No problems yet.
Not cheap, however cheaper than the MOs I used before (does anybody remember those ?).

Of course for the standard backups I use external USB drives.

I've been using them as well. Of course, I don't depend solely on them for my backups, but consider them as a bit of extra insurance.
