Sometimes you run into surprises with particular media manufacturers. I blaclisted Fuji
when 100% of my Fuji audio cassettes failed (media failing such that playback would be
overwhelmed by squeaky noises heard on the playback, not just the drive mechanism). No
other brands did this sort of wholesale collapse, and most haven't failed at all, not
even the cheaper ones.

I am interested in whatever media are more likely to still be readable in a few decades.
M-Disc claims 100 year life, but, obviously, no M-Disc has lasted that long, and they are
making promises based on what they THINK will happen.
M-Disc BDXL is currently available in 100GB per platter.
In the early days of this list (think back 25 years), I believe it was Tim Shoppa that
was recommending either Gold CD-R blanks, or Verbatim DataLifePlus. If I remember
correctly, he’d done some aging tests on them, and they were the two that held up well.
As a result, I standardized on Verbatim DataLifePlus for any CD’s I expected to be reading
after a year. I’ve read ones from 1997 without problem. In fact I think I’ve only had a
couple minor issues. One of the disks I read had to be washed before I could even attempt
it as it has been sitting out bare.
What has surprised me is the results from the floppies, mostly stored in the garage for
the last 15 years, and before that, I don’t remember. Granted I tended to go with higher
quality floppies, but still, I’ve expected a lot more issues than I’ve had. Some of the
3.5” floppies I’ve read date back to 1987 or 88. Mind you I’ve not tried to recover data
from 5.25” floppies yet, I’m still trying to find those, and a big drawer/box of 3.5”
floppies.
