Ah, thanks! I missed it when I searched because I mis-scanned it
as raidle instead of raid1e.
RAID 1E would be less likely to be misinterpreted.
So, it should have write performance somewhere between a pair of
drives in RAID 1 and four drives in RAID 10, assuming the
controller hadles it well. I'm still curious to see raw I/O numbers
for random and sequential scan against the array.
