Solved:  Looks like it might have been an installation error. I removed the NVME drive and reseated it in the slot and now speed seems to be what it should be.  I'm surprised that it didn't error and was able to benched in the first place.
I just installed a second NVMe SSD and the speeds are super slow. The system came with a WD SN810 and speeds are normal >6000MB/s Read/>4000 MB/s. I added a 1TB WD SN730 pci-express gen 3 nvme to the second m.2 slot. In my other system this drive was getting ~3000 MB/s read/write and now it's in the 200 MB/s Read/ 150 MB/s write.  I tried messing with BIOS settings. System was in RAID mode then i changed to AHCI/nvme and reinstalled Win 11 but speeds are still the same. I also made sure all SSD firmware was up-to-date and made sure all other system drivers/BIOS was updated. I tried reformatting and running trim on the drive. I also tried loading optimized BIOS defaults.  Current system BIOS is 1.2.1.  Any insight would be appreciated.   [IMAGE]
