I bought and installed a 2 port SATA controller model# SY-PEX40039 ($14). It is bootable if this is your primary drive. If you use the latest drivers from Syba's site (recommend), version 126.96.36.199 you must use the installer to install them. If you have windows try to find them from device manager in the extracted direcotories from the downloaded driver zip, the system will bluescreen and then bluescreen on reboot. Pain to revert if you didn't make a restore point. Connected to the SATA card, Crystal Diskmark performance is very good and AHCI is functiontioning. The 860 drive plugged into the card outperforms my older 830 drive plugged into the mainboard. The only drawback is that Samsung Magician does not recognize the drive. I also found that if I configured my SATA ports on my motherboard for IDE instead of AHCI that the 860 drive was stable. However DiskMark showed very poor performance which is to be expected in the absense of AHCI. Hopefully Samsung releases a firmware update to resolve this issue. In the meantime the SATA card seems like a good option and performance is very acceptable.

I am in US and have this issue with EVO 860 512GB. Returned the first drive and got a brand new replacement and same issue. Random SMART CRC errors which cause system to hang. I have an ASUS M5A97 R2.0 which uses the 970 chipset. My older EVO 830 drive works fine. I just purchased a 2 port SATAIII controller and that may be the best option. I'll report back.
