Slow SSD Write Speed

Slow SSD Write Speed
Windows 10 build 1909

Recently I have installed 480 GB AS340 PANTHER SATA III SSD. I was getting good Read and write speed well above 500 MB/s Read, and 300 MB/s write. But it's been one week now I am getting my writing speed throttled in a midway. From stable 250 MB/s for
3-4 write to 10 MB/s.
I also attached a video demonstrating this problem.

FYI I have Intel(R) 6th Generation Core Processor Family Platform I/O SATA AHCI Controller installed.

M2 NVME SSD

I found this on a website called velocitymicro:

"Modern motherboards use SATA III which maxes out at a throughput of 600MB/s (or 300MB/s for SATA II, in which case, it’s time to upgrade). Via that connection, most SSDs will provide Read/Write speeds in the neighborhood of 530/500 MB/s. For comparison, a
7200 RPM SATA drive manages around 100MB/s depending on age, condition, and level of fragmentation. NVMe drives, on the other hand, provide write speeds as high as 3500MB/s. That’s 7x over SATA SSDs and as much as 35x over spinning HDDs!"
