Sorry guys but another post from me about archiving - this may interest some of you though.
After my scare last night I’ve been doing a bit of reading on the best method for long term archiving of my digital image files. Hard drives in constant use are only rated for 3-5 years before issues can start due to the magnets etc. External drives sitting stored may last a decade or two but will eventually degrade.
It seems the best option for prosperity is M-disc media. They can be read and written to by standard blue ray recorders and are readily available. Extract below from a website I was reading -
“Write-once BD-R HTL (High To Low) can last for 100 to 150 years given a relatively mild environment—i.e., not on your dashboard in Phoenix. Milleniatta’s M-Disc BD-R and DVD+R write-once discs use an even more stable data layer that is rated for 10,000 years. Only its polycarbonate outer layers reduce that to a mere 1,000 years. Note that this is all theoretical, but the testing MOs were rigorous and performed by the government of France (BD-R), and the Navy for the Department of Defense (M-Disc DVD).
Available in 25GB, 50GB, and 100GB (currently very expensive) flavors, BD-R also has enough capacity to handle long-term backup and archival chores. The downside is a relatively slow 21MBps writing at best—substantially slower than USB 3.0 hard drives and SSDs.
If you’re worried about optical drives disappearing, know that optical retains a very strong presence in the archival community, as well as the enterprise, so that should give you some reassurance.
Advice: Despite its slow speed, optical is pretty perfect for archiving your most important data.”
Not ideal for everyday backups but potentially the best option for passing your images on to future generations of your family
There’s also the issue of disc size. Depending on how big your collection is it could end up spanning a lot of discs

I'de stay away from BD-R, too much work. I came from an era that DVD-r was common, and I still have stacks of those things. I transferred to hard drives. If it's too much trouble, it wont be done.
if you want to prolong your NAS, look into the sleep settings, I have mine setup to hibernate after 30 minutes (sweet spot with experimentation), so they basically stop spinning most the time. My drives are well past the 5 year mark. Ones that run at my moms are probably 8-10 by now, that's a pretty good lifespan!
Great shot!
