[Discuss] SD Cards, cheap and here for a while?

I saw something a few months ago.  SD cards are not recommended for
long term storage,
and the current best manufacturers are SanDisk and Samsung, according
to the article.

There is no great long term archives.  Some '1000 year archival DVDs'
like Verbatim brands
seem to be some of the best, currently, but even those have a l3imited
lifetime for 'near absolute'
recoverability of data.  Tapes are great, but even those need
maintenance annually (wind/rewind just
to keep the media from 'sticking'), higher density drives and storage
methods that use smaller bits
can have bit-rot from stray cosmic rays or mechanical dings.  But
keeping all data online is
waiting for a hacker and power surge to take it out.

Yea, I spent way to much of my life worrying about such things for
companies. ... For most
mere mortals, the 3-2-1 of backups backup is pretty good.

Working for a company, they didn't believe me when I kept harping on
offsite backups should
at least be in another town.  Then flood waters took out the 'offsite
storage' location that was
'cheap' that was only 5 miles from the main data center.  After that,
we shipped monthly's to
another town and offsites went to a commercial vendor (IronMountain at
the time).

Sorry, I get caught up in war stories. ... I hope this helps someone. ... Jack
