I've got a 256 GB SATA SSD that currently holds my OS and a 1 TB hard drive for other storage. Recently, I picked up a 1 TB NVMe SSD and I'm considering transferring my OS over to it. Since the SATA SSD only contains the OS, I wouldn't be losing any personal files, but I'm a bit worried about possible issues. I've heard that it's sometimes better to keep the OS on a separate drive. What do you all think?

If you're worried about it, you could always partition the NVMe if you want. But honestly, if your SATA SSD booting fast enough, you might just want to leave it as is. Next time you reinstall your OS, you can switch it over then.
Starting fresh is always the best way to go. You'll likely have fewer issues this way.
I suggest unplugging the SATA SSD and connecting the NVMe SSD before doing a fresh Windows install on it. Once Windows is set up, you can reconnect the old SATA drive, back up any files, and then use it as extra storage.
The idea of keeping the OS on a separate drive hasn't been a recommendation for ages. Your OS should be on the fastest drive—so go ahead and transfer it to the NVMe. For most people, it's simply a better setup to have everything on that fast drive without any real downsides.
Moving it won’t really make a noticeable difference for you, honestly.
Definitely move your OS to the NVMe if possible! Your boot drive should always be your fastest drive for the best performance.
