Each test was ran in a clean system just after reboot (via rc.local). I used 512MB chunks, but I guess that was not enough, as corruption didn't show itself in all the tests. Also there seem to be some problems with NFS on current witch need specific attention - that's why I lost one sample due to NFS lockup and reboot, and that's why I've used 512MB data pieces. 1. 512MB zeroes with netcat: 5/5 correct 2. 512MB zeroes with NFS: 4/4 correct (there seem to also be some NFS lockups on -current, so I lost one sample; it's also the reason I ve 3. 512MB random bytes with NFS: 2/5 correct also tried 512MB random bytes after 10MB via netcat and same 512MB after that (to check for possible shifts). No corruptions here, though. So I only have 3 corruptions. Will do more tests when I have some time. Those reboots take quite a lot of time and need attention due to possible NFS lockups... For now guess is that corruption may be data from the other place of the stream. So stream of zeroes is not affected (or is affected with much lower possibility).
