error -36 on a brand new samsung 850 ssd drive
Judging from the symptoms, I would test the following:


Check macOS. For instance, boot from the Recovery partition or create a second partition with a virgin system and try to copy the files causing issues.
Check the SSD. 


Check SMART info of the SSD.
Best remove the SSD and place it either in an external (USB) enclosure or into a different machine. Then test your drive from there. You can also boot from an external drive by pressing alt during boot. 
Also try to get hold of a Windows PC or boot from Bootcamp and use the Samsung your SSD with the Samsung Magician. However, keep in mind your SATA cable may be the culprit (see next step).

Check SATA cable: The SATA cables of the unibody MacBook Pros are known to cause all kinds of issues. In case your SSD proves to be ok, consider replacing the cable.
