You can try chkdsk in Windows. CrystalDiskInfo also has a test.
Samsung also has its own monitoring software:

There is also a driver for a few of the drives:
"This driver supports Samsung NVMe SSD 970 PRO, 970 EVO, 970 EVO Plus, 960 PRO, 960 EVO and 950 PRO."
Apparently the 951 is the OEM version of the 950 PRO:

There is also updated firmware for the 950 PRO. However,as the 951 is an OEM drive,I am not sure if any of it will work(might bring up the wrong flags). It appears you can get updated OEM firmware and drivers,but might need to check relevant forums,to point to where they are available.
There is a long thread about the 951 on Overclock.net:

Some people have had problems with newer Windows updates.
