I've been using the Samsung 990 Pro with my X870E for a few months now. Zero issues and the performance is incredible - getting around 7,450 MB/s reads. Just make sure you update your BIOS before installation to ensure full PCIe 5.0 compatibility.

SN850X is one of the best choices. 

The new released Samsung 9100 PRO PCIE 5.0 SSD is a good choice.
