The tech has been around... well, Wiki says it was first demonstrated
in '96. "Finally" is a bit of a misnomer. ;-)
 
IIRC, though, it has several downsides. Biggest is that it is extremely
slow with writes (and pretty slow with reads too). And even if it had
"HDD-speed" read/writes... well, back-of-the-napkin math indicates it
would still take close to 3 DAYS to read all that data (about half that
if it were SSD speed). We'd need advancement in the IO first to really
make use of drives that big.
 
It's also write-once, which limits its use to archival. So it's not
gonna replace HDDs or SDDs any time soon.
 
 

Now Spalls can fit all his games on one disk about the size of a
quarter and not worry it's going to die of bit rot.

 
I've over the years transferred pretty much all of my DOS-era games to
HDD (twice actually; first as images of the original medium, and then a
second time to a different HDD where the games are actually installed).
The installed games takes significantly less than a single terabyte,
and that collection includes probably every DOS game you've ever heard
of (and a few more too ;-)
 
Disk-space is so cheap and readily available already that -while I
wouldn't sneeze at a long-term archival medium- it's not really
necessary. It's surprisingly hard to fill up multi-terabyte sized disks
under ordinary usage ;-)

$ df -h -t nfs4
Filesystem                    Size  Used Avail Use% Mounted on
192.168.23.12:/volume1/ds      39T   26T   13T  68% /nfs/ds
192.168.23.12:/volume1/music   39T   26T   13T  68% /nfs/music

Space is getting a little worrisome, but I have a new Synology filer
sitting in its box, as well as drives.  Just haven't gotten a round tuit.

Most of /nfs/ds is backups of my workstations throughout the years.
My music collection is flac ripped from CD's, which I often lose track
of...

However, there is this:

_[/nfs/ds/scott/src/OS]_(scott@lm)🐧_
$ du -hs
853G .

850G of built Linux kernels.  (I'm a digital hoarder,
and having an NAS hasn't helped.)
