    It should be noted that the 860 Evo Series has serious problems with some AMD SATA II controller. I have a 1 TB SSD and with the SB710 chipset I get CRC communication errors and the connection sets to its lowest 1.5Gb/s. There is a kernel bug report:

    A firmware update from Samsung would be appreciated!

      I wish I'd read this a couple of weeks ago before I bought a 2TB 860 EVO for my old AMD based system. I've since disabled NCQ and the performance dropped about 10%. When bulk copying photos the effective transfer speed went from 515 MB/s to 465 MB/s. The decreased speed is still acceptable, so I'm going to live with it.

      I guess I could buy an inexpensive PCI controller, but that may lead to other issues.

      Instead of totally disabling NCQ, it would be interested to see if a reduce NCQ value (say 8) would also eliminate the errors. But this is my /home drive, and I'm not messing with it any more than is necessary. There was some analysis done for Intel drives where 8 seemed to be a good minimum:
