RAID 6 (and 5) perform well when less than approximately 1/3 full.
After that, even reads suffer.
Mark,
I've been using various kinds of RAID for many many years and
was not aware of that. Do you have a link to an explanation?
Thanks,

YMMV.
I should explain better. Three-drive motherboard-fake-RAID-5's perform
abysmally when they start to fill up.
I do not have a link handy. I could try to find some, if you like.
In my experience, real-world performance is always less than theoretical
or reported performance. That is, I've never had a RAID 5 work as well
as advertised. If you have had better experiences than me, more power
to you.
MAA
