I am still waiting to use my DVD-RAM drive capabilities...

But, i was assured back in the 80s that optical media was already indestructible. lol

Depending on read speeds and costs, I would be somewhat interested in this. For some home media servers, reliable high-capacity optical drives still make sense. You can fit a lot of music and photos in 1TB. If you want high-quality 4K movies, there aren't too many drives available that can affordably store many of them. As of right now, I find Blu Ray way too overpriced for its capacity, especially when you consider how inconvenient it is. Otherwise, the read speed is nice.

Optical disk is arguably the most reliable storage medium available due to potential longevity. The info in this article is intriguing news for 1% of the people who know about these things. 😉

Here's another thing one or two of us may find interesting:
DNA digital data storage

You're one hundred years too late.

But we were supposed to get 3D Holographic storage cubes for that...

i wonder how much we can trust this
Because optical discs have a long life, unlike hard disks and magnetic tapes, there is no need to regularly migrate data from degraded media to new media.
i have seeing some of my CD audio collection degrading ... basically the polycarbonate layer is degrading... some degraded by mold, when we touch the CD sometimes our hand not really clean, those oil, dirt on hand got stick to CD, and over period time it turn to some kind of mold...
especially if you live in humid area, u want to make sure your CD collection in dried storage
other than that, UV light also easily kill any optical disc, especially those dvd-r/bd-r
so the term "long life" is in maintaned condition ... not normal/standard storage i think
but after reading it again, i think its more about data retain in optical disc, rather than the media itself
optical disc retain data much better than magnetic tapes that data might degraded over time

@RzrTrek
why? cause you dont need it?
so we gonna get rid of all the stuff only the "pros" use?!
@slyphnier
1. cd/dvd/bd and STORAGE things like RAM (dvd) are not the same.
2. most IT stuff wont be eating a McRib while handling the disc, so no degrad by dirt.
3. you usually dont have lots of server/data rooms that have windows, ergo no UV (sun light) coming in.
4. most the time the disc are stored in a case and that goes into cabinet or similar.
at least the places where i worked it.
my main problem is with the burn speed. i could never find burners that would support the 8x/12x.
than BD was giving me more space, and now that i swapped all hdds for ssds, its even "worse" (performance when backing up data)..

i use DVD-RAM for archival few years ago... indeed far better than standard DVD/BD-R
especially the one that incase and you have DVD-RAM recoder that support cased DVD-RAM (like this one http://www.tdk-media.jp/media/dvd-data/bbf39800.html)
but still it will degrade as it using same material/polycarbonate
TDK has been making ultra tough BD-DVD-RAM / -R
that said UV + scratch resistance
like this http://www.tdk-media.jp/media/dvd-camcorder/bbd44800.html
i use some for archiving back in 2006~2010, will check the disc physical condition when i have time later
but i believe nothing can really UV resistance... and DVD-R is really sensitive to UV, even indirect sun-light or fluorescent bulb that have some uv can damage those DVD-R over time
it doesnt need a really dirty hand to make a mold
for people have dry hand it should be fine... but just some sweat will enough to grow mold on the disc
most people dont clean/wash their hand when handing the disc normaly, right?
so even say they dont eat while handling the disc, but its not like their smartphone is clean either, so do their hand
if the cabinet in air conditioned room, probably it will be fine... but cabinet in hot steamy summer... bet some of those will start degrading over years.. i am talking more than a decade though.
not sure why u have problem with burn speed, even its slow, you can burn while other job right ?
burning BD nowdays dont need to be focus on burning ... it wont fail even you start doing other job
for SSD i am not sure why u pick over HDD... price and capacity wise not make sense to me
i would rather use cloud backup rather than SSD
