I have similar issues on my home workstation. They started

I do not believe this to be an issue with ZFS. I've largely
dismissed the issue as hardware caused, although I may be wrong.
This system has had several problems with SATA-II drives which
hardware forums suggest are issues with the nForce4 chipset and
SATA-II.
Anyway, your not alone, but its not a ZFS issue. Its possible a
tunable parameter in the SATA drivers would help. If I find an
answer I'll let you know.
The drives are WD5000YS, which are SATA2, so it could very well then
be what ever NCQ & SI3124 issues there are. Sadly working in grant
not for profit medical research we don't have the money for any more
hardware
If there are anythings to tune anywhere to give me a steady/
sustainable performance I would greatly appreciate it.
The built in compression & snapshot make zfs worth it, but not at
such a slow speed
Thanks-
