NONE, really.

If you need long-term, optical is kinda IT.
I'd suggest "M-Disk".

Mag disks can be FAIR - but CAN suffer from "bit rot" after awhile.
Which is why if you value your time, you'll invest in a decent
NAS, and pay attention to the disks when they complain. If a disk
starts to fail -- swap it out!
Been there, done that - a lot.
However "bit rot" can happen even on otherwise
perfectly good drives. They pack the magnetic
stripes in SO close these days that they are
prone to "fading" after x-years. In theory
a good error-correction scheme MIGHT rescue
you - or not. The worse prob with bit rot is
with compressed/encrypted files where a prob
with even a bit or two can thwart recovering
the file since what follows can be very dependent
on what came before.
However running a utility that reads and re-writes
disk tracks WILL work. I think you can find 'em
online, or write yer own. Even 'dd' can be scripted
for the purpose.
It's NOT as easy with 'e-disks', M12 and such,
since the data doesn't stay in the same physical
place due to wear-leveling algos. This moving-
around CAN be good, or not.
I recommend Synology -- not only because of its Linux underpinnings,
but its excellent management software: a desktop metaphor, controlled
through a web browser. You can also ssh into it.
My last NAS was a Sinology - it was good and
quite versatile and the price was fair.
Oddly, at this point, OpenMediaVault is a pretty
good NAS - and free. It DOES have a few weirdnesses
however. Setting up temporary shares for safe
backup purposes is a bit odd, you can't write
directly to the disk dirs or it won't index
the files, gotta make local SAMBA/NAS share that
loops thru their system.
If you do buy one, I recommend getting one with 10G Ethernet (at least),
and making sure your system has a 10G (or better) connection to it.
The one I had came with a little card slot FOR a
10gb card. However the building wiring was a mix
of cat-5e/6, and only because I insisted on that
long back as "future-proofing", so there was no
point in 10gb. NOWdays, more and more idiots use
wi-fi for everything - and just ignore or are
oblivious of the performance hit involved.
"Why does it take so long to load my GIS files !"
"Waaaaahh !!!"
Even more recent, everybody started storing their
working files in the Cloud - even WORSE speed hit
AND the Russians can obliterate everything easy.
