Speeds way slower than advertised for a new NS850 1tb drive

Hi all,

I recently got a WD Black SN850. It is very fast on general use BUT when running some benchmarks the numbers I’m getting are wayyyy below what others have posted.

I’m trying to work out what’s preventing it from getting close to its supposed speed

My system is:
CPU: Ryzen 9 5950x

MB: MSI x570 Gaming Plus (with latest bios)

GPU: GTX 1080ti

RAM: Crucial 16Gb (2x8gb) 3600mhz

PSU: Seasonic TX-1000

The SSD temp was in mid-30 degrees celsius when running Crystal Disk Mark

What speeds are other users posting then?
