My motherboard is B450 Carbon Pro AC and I had to unplug my HDD in order to clean reinstall windows in my m.2 boot drive. After plugging it back in and copying the same file I noticed that I dropped 30MB/s write speed.

My Write speed used to be 183MB/s but now it's dropped to 153MB/s

Are the source and destination drives the same in those two screenshots, they don't appear to be?
Yeah in the screen shot above I was copying the entire folder and sub-folders within it. Even after copying the same file in the same folder as I did in 183MB/s screen shot my speed stuck at 153MB/s, there was no difference.
