I tried with two different connectors but the problem persists. However,
I noticed that the problem only appear at high I/O rates (during a
graid3 resync for example): the machine runs Bacula and the backup job
completed successfully this night, but it was a remote machine so the
I/O writes didn't go above 2 MB/s ...
Do you think the problem could be the firmware of the disk?

No trees were killed in the creation of this message.
However, many electrons were terribly inconvenienced.
