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

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.
On another test box with an MPR controller and same WD drives, a few
more messages after the zfs send is about 50% done on a dataset thats
about 1TB but compressed to about 260G. Some 29 million files. But with
Samsungs, reliably no issue :(
