"CAM status: SCSI Status Error" suggests to me that the drive was just too busy

Given enough of them it does cause checksum errors on the test pool
unfortunately. Could a buggy TRIM play a role here too ? I noticed a
commit the other day for a Segate SSD that had a broken NCQ TRIM. Could
these units suffer from that ?

Is there a way to turn that off via camcontrol ? Or perhaps instrument
some other settings ? I am not wedded to this hardware, but it would be
good to know if they can be made workable without too much effort.
