Well, sort of... It's because I may need to.
I not only store TV shows, I do commercial backups for companies. Sort
of like rsync.net, only better. ;-)
So my once-ample 1.5 TB array has been filled to capacity and then some.
The idea is to get a box that I can stick in my rack, and then add 1TB
drives as needed and grow the array. The box would only be a NAS; no
processing at all. Since the streams are limited to mythv + internet, a
gigabit connection should be ample for the forseeable future.
If I can figure out a path to a 20TB array that I can implement today
with, say, 3 1TB drives, and add drives as needed, I may be ahead of the
game for a few years.
What I don't want to do is to implement a solution today and then have
to rip it out a year later. If nothing else, do you have any idea how
long rsync takes to dump and verify a TB over an ethernet connection? 2+
days, and it's not quite done..... I hate to think what I'd have to do
with a 5 or 10 TB array.....
