I read that the far layout gives faster read performance compared to
standard RAID1 in a 2 HDD array, so that's why I used it. I then
created yet another RAID10 f2 layout of the 3x 2 disk RAID10 volumes,
giving me /dev/md124. Filesystem doesn't matter, I need something
that's stable with good performance over the RAID set.
I just realized that out of 12 TB raw space I now only have 3TB
available, heh. So I suppose I'm going for a different layout.

Any opinions?

Hello,

Why won't you even consider RAID6? To me it seems like the perfect choice,
given the details you described (mostly reads, large files, few clients).
And the disk count is perfect, not too few and not too many, so to say :D
