What to do?

I've recently acquired a 1TB 960 EVO nvme SSD.

I already have a 250GB 960 EVO and thats where my C drive etc is.

I'm debating on removing the 250GB and reformatting to use the 1TB as the single drive. I'm just questiong if anyone sees anything wrong with this thought process? I typically use a small drive for c.

I also dont plan to use the 250 in this PC so the new 1TB would be c drive..storage..everything in 2 partitions.

or.

Better to leave in the 250GB, not reformatt and use the 1TB...
