Is this speed acceptable or is my ssd defective

Hi everyone,
I just bought a WD Blue SATA SSD 1TB a few days ago.
Below is my compression benchmark with AS SSD.

Compared with the benchmark of the same WD SSD I found on the Internet, my SSD obviously performs worse, especially in writing speed.

My system is Razer Blade 15 Base 2019.
Motherboard Chipset: Intel HM370 (Cannon Lake-H)
In WD Dashboard, it says my firmware is up-to-date.

What could I do to increase the performance of my SSD? or should I return it for a new one?

Here is another benchmark with CrystalDiskMark, my writing performance (top image) is worse than the other benchmark on the Internet (lower image).
How could I improve my SSD performance?
