New SSD Underperforming?

[ItsCanada]

So I finally decided to add a second SSD to my system. My first one is a 1tb Samsung 850 EVO which holds everything on my computer and the new one I just installed is a 2tb 860 EVO. Now my 850 performs great and always has, but when I bench marked my new 860 it's showing pretty sub par read and write speeds. At first I thought maybe it's just showing that because it doesn't have anything stored on it, so I filled it up a bit, but still got the same result. It's my understanding that the 860 is supposed to perform slightly better than the previous generation. I ran the full diagnostic scan in the Samsung Magician software and it came up with no problems. Another thing that concerns me is that when I run the program UserBenchmark to benchmark my system, the system crashes when it gets to testing my 2tb drive and I'm not sure why. Does anybody know what the problem might be? How should I troubleshoot this? Is this a faulty drive?

Are you sure the SSD is plugged in a SATA 3 port? If so, I would try to switch both SATA data cable just to make sure it's not an issue with the motherboard or the cable.

Yes my motherboard is the Asus MAXIMUS VII HERO and it is plugged into one of the 8 6GB/s SATA ports along with the boot ssd

You can try to switch both SATA data cable just to make sure you don't have an issue with one of them.
