SSD would be very unsuitable for archiving.
But, it is a nice fast medium for short-term uses.
AND, it MIGHT be the first to get a unit larger than 2TB that will fit in 
a thin 2.5" form factor.
Probably better SHORT-TERM reliability than the Seagate 2TB thin SATA 
spinning rust.

What is the archival life of a BDXL, other than M-disc?
M-disc media is a bit expensive.
It looks like an excellent medium for data collections a tenth the size of 
what I'm playing with.

It seems that it is still necessary to maintain multiple copies 
(geographically separate - we had a 4.4 quake yesterday morning), on 
multiple different media, and make new copies on a regular basis.
