Hi, Spike:
Maybe I can offer a few useful comments and observations about
long-term storage...
It's my experience that optical discs which are not commercially
manufactured don't store well except under ideal conditions - cool
place, low humidity, no sunlight. By "commercially manufactured" I
mean that the data is already on the disc when you buy it. Discs [CD
or DVD] that you burn the data onto are the "not commercially
manufactured" ones.
The reasons for this are varied, and you just can't get away from the
inherent problems. What happens is moisture finds its way into the
recording layer and causes it to bubble and flake off. When that
happens, you can kiss your data goodbye.
There is an alternative. External hard disc drives.
I don't know about prices outside of Australia, but if you look around
a little, you can buy 4TB [actually 3.63TB] hard drives for just under
$AUST200. Blank DVDs [4.38GB] are about $0.40 each. Do the maths and
it works out that 828 DVDs = 1x4TB disk, which means that for
equivalent storage, DVDs cost about $330 compared to the EHDD $200
I've been using EHDDs for nearly 10 years now, and I've NEVER had a
failure. I use either Western Digital or Seagate.
I currently have 12 EHDDs on 3 separate computers
