Your friend blog entry is also very interesting, although maybe a bit optimistic on the "no data corruption guarantee" unless he has pre-existing data checksums to confirm that. That would be some "experimental" proof of ZFS error correction effectiveness. > > > I emailed the internal ZFS interest list with my saga, and quickly got a > > response.

This was due to a bug in the 3ware controllers, that did not work reliably when installed in the PCI-X slots of the mainboard (it's in 3ware publically available support knowledge base).
