Question Very low SSD transfer speed

[Walfools]

The boot drive in my build has recently been suffering from very low transfer speeds. I ran a test on the drive and the results appear normal, but when I try to actually move/copy files its very slow. I have tried some common fixes, including enabling AHCI, and changing the Advanced Power Management through HD Sentinel. For some context the drive is a 2.5in SATA SSD by Western Digital. The model name of the drive is WDC WDS500G2BOA. I believe the drive is discontinued as I cannot find any information about it on Western Digital's Website. I will attach some images below of tests and general information about the drive.

Looks normal.
Transferring a lot of small files is usually much slower than transferring large size files.

I looked into it a little more and i think the ridiculously slow speed was due to the amount of files in the folder I was moving (about 650k). Thanks for your help!
