qqnorm(), is it "backwards"?
...kurtic distributions to go
the other way (eg pg 117 in _Biometry_ Sokal & Rohlf, 3rd ed).
The same thing with skewed data, I expect right skewed data to show a
negatively accelerating shape, but qqnorm() curves upwards.
Am I missing something, or is qqnorm() consistently heading in the wrong
diirection?
Cheers,

SAS/short stroking vs. SSDs for ZIL
Hi,
as I have learned from the discussion about which SSD to use as ZIL
drives, I stumbled across this article, that discusses short stroking
for increasing IOPs on SAS and SATA drives:
http://www.tomshardware.com/reviews/short-stroking-hdd,2157.html
Now, I am wondering if using a mirror of such 15k SAS drives would be a
good-enough fit for a ZIL on a zpool that is mainly used for file
