SSD errors

I have 4 SSDs in zfs raidz2 on 11.0-RELEASE-p2. There on QD sleds rated
for sata6 to convert them from 2.5" to 3.5 slots in a Supermicro SC733TQ
chassis (2012) with a Supermicro X10SRi-F mb and using the on-board
controller (either one). I swapped the SATA cables for some with "extra
shielding". And the 4 HDs used previously (mix of WD and seagate 750g
and 2T) worked flawlessly.
The bios has a "SATA Device Type" option for SSH/hd, which is set to SSD
and seems to only apply to spin-up signals. The chassis manual makes no
reference to SSDs, I have found no fbsd configuration or recommendations
specific to SSDs.
When I push a lot of data to them, such as an rsync, I receive errors like
the below. If I move drives between slots, it seems to follow the chassis
slots, those closest to the power supply, but I'm not positive about this.
I suppose the questions for list are:
- have I missed any fbsd ssd-specific configuration?
- all 4 have non-zero UDMA_CRC_Error_Count counters; not many, about the
same number, which I believe implies electrical interference - most
likely in the cable or chassis backplane. Should I buy some specific
model cable? other recommendations?
