Thanks a lot, that was a very detailed elaboration and I certainly
appreciate it, got me thinking of my overall system and how to possibly
arrange it. These things can get quite complex, indeed!

Sounds good!

I suppose the last hurdle is to determine whether or not to build one big
array or perhaps 2 or more separate ones. I am set on a minimum of 6 drives,
likely 8, x 2 TB, and RAID 6. I'm currently simulating rrays in Virtualbox
to fiddle around and get some experience doing it myself first.

What are key considerations if for example I have 6 x 2 TB, in doing a 6x2TB
array vs. say, 2 x 3x2TB? I don't want to overcomplicate things so if one
big array is a fine path I'll do it, but this thread has shown me how
frakkin much "fine print" there is with the whole RAID deal :)
