Question is my NVME screwed? weird write speeds

[Quadro-X]

I have this exact drive: https://www.gigabyte.com/SSD/GIGABYTE-NVMe-SSD-256GB#kf

• Form Factor: M.2 2280
• Interface: PCI-Express 3.0 x4, NVMe 1.3
• Total Capacity: 256GB*
• Warranty: Limited 5-year or 300TBW
• Sequential Read Speed : up to 1700 MB/s**
• Sequential Write speed : up to 1100 MB/s**
• HMB (Host Memory Buffer) supported
• TRIM & S.M.A.R.T supported

But my read/write speeds seem a little off compared to what is listed here. Is it because my C:\ drive is quite full? B550 motherboard (so nvme is plugged into PCI-E 4.0) and Ryzen 5600.

Write cache enabled?

Seems yes, it's enabled.

Reduce the consumed space, and try again.

Also, install and run the gigabyte utility.
I believe there is testing function in there.

Will try; another note I'm not on the latest BIOS.

Will try; another note I'm not on the latest BIOS.

And fix that as well.
