OK. So I own a 32 GB flash drive that transfers files at an average speed of 75 MB/s when I plug it into one of the two of my USB 3.0 ports. And I just bought a Samsung 128 GB thumb drive that whenever I plug it in SPECIFICALLY to a USB 3.0 slot, it transfers files at an average speed of 25-30 MB/s. It says on the packaging that this 128 GB thumb drive should be able to transfer at speeds of up to 150 MB/s.
And trust me, I've tried everything I could think of. I have Windows 10 and went onto Device Manager to see if there was a need for a driver upgrade. There wasn't. I reformatted it to NTFS instead of exFAT to see if that would do the trick. It didn't. In fact, it went slower. I even added a registry key that someone told another user in these forums to add to their registry in order to remove all "ghost drives", whatever that means! I even went to the properties of the drive and selected the "better performance" option and it didn't do much of anything. I even went back to the store I bought it from and tried to use a different 32gb thumb drive than the one I have and a different 128gb thumb drive than the one I bought to see if it was because the thumb drive themselves were different in storage capacity, and thought perhaps that's why it's slower, and basically every thumb drive I have tested aside from the 32gb one that I currently own are all transferring at a much slower speed than the 32gb drive I currently own. I need a real expert's opinion here because it's been driving me crazy!! Please hallllp!!!
 
I don't think you will ever see 150 MB/s, but it should be 3x times faster than what you are getting.
Try testing it on another PC
If it doesn't get faster transfer speeds, it could be a counterfeit USB drive.
I got a couple of those from amazon and they did not even had the advertised capacity.
I checked with an app that detects fake drives.

It's not counterfeit. I bought it at Microcenter. And I know it's not the brand because I tested another 120GB hard drive from a different brand and it did the same thing. And like I said, my other thumb drive that I bought from over a year ago is working just fine with my USB 3.0 slots. I don't know why specifically it's that drive that goes fast while all the other ones from both similar and different brands and different storage capacities go slow. Why does it like one thumb drive but hate all the rest??? Ugh it's driving me crazyyyy!
