External USB Blu-Ray drives under Linux?

[ted leslie]

bluray not reliable? so you need far more then 100year retention? what
are you doing that needs that?
I still have cd's from '88 that are good , and some that are totally
screwed, but I believe a good disc like a panny BD
could get 100years of life even in poor storage env. A 50gb BD will
also be 0.50 in time (couple of years), but then they have
300gb ones on the way to (so have to buy a new drive), but BD is
likely to be a standard for reading for a while, i.e.
CD will probably have a production life of 40-50years, so i could see
BD devices still sold in 2040+. (or at least will read BD, and 1tb BD
or whatever as
time goes on).
