USB 3.0 transfer speed is slow on my laptop. This started recently, and I’m almost pulling my hair because data transfers are crucial to my photography job. I need help please. How do I fix this mess? Thanks.

Computers offer you several methods of transfers; wired and wireless. More than 60% of all computer transfers are wired and done with a USB. If your USB 3.0 transfer speed slows down suddenly, then this post is for you. Here, you will find reasons for this issue and ways to fix it.

Part 1: Cases and Causes of USB 3.0 Transfer Speed Slow

To appreciate what I mean when I say a USB 3.0 transfer speed slows down, let’s look at the following cases:

“I purchased my flash drive and noticed that it sends and receives data quite slowly. My old flash clocks around 20MB/s if I remember correctly. How come this new one does not go above 50KB/s?”

“After upgrading my laptop to Windows 11, my USB 3.0 thumb drive now takes hours to copy data. I use the drive a lot with my home theater, and it’s quite frustrating. It copies at speeds as slow as 2MB/s”.

Reasons for USB 3.0 Transfer Speed Slow

If your USB 3.0 transfer speed slows down from say 450MB/s to 3MB/s, know that it can be caused by one of the following factors:

You recently upgraded from Windows 7 or 10 to Windows 11.

Formatted the USB 3.0 flash drive.
