I don't recommend the Samsung for the BMPCC 6K Pro.
I have several Samsung T5 SSDs in use with the BMPCC 6K Pro, which work fine but cost much less. The Scandisk is much bigger and more cumbersome. For the Samsung there are also holders for mounting on the case (SmallRig etc).

I would have to have the 6K pro first, in theory it should work.
