a pool using 3x Samsung 850 SSDs on a LSI-9211-8i (IT)

if lowering the write amplification on the pool-drives would
help, so I added another matching SSD for that, but under load
I still seem to get extensive checksum errors. Does anyone
have any ideas as to what would be causing this?</font><br>

I would look for jbod SSD placement guide, they seem to be pretty
sensitive to where they physically live.<br>
