Overview of Slow USB Transfer Speed (Causes & Symptoms)

Generally, the USB transfer speed will slow down when you have one of the following issues: 

  • Unstable power supply in the USB port. 
  • Bad sectors slow down USB.
  • USB file system slows in transferring big files.
  • The USB port is old and not compatible with a new USB drive.
  • USB drive gets full and slows down in transferring files.

So, how do you judge if your USB has a normal transferring speed or a slow one? Follow and check this out:

#1. If USB has the below symptoms: #2. If USB is slower than its stipulated transfer rate:
  • 1. The file transferring process never ends.
  • 2. USB doesn't start transferring or time lasts hours or even a day.
  • USB 3.1 - 10GBps
  • USB3.0 - 5GBps
  • USB 2.1 - 480Mbps

Here are the steps to connect USB to the rear port and speed up USB file transfer:

Step 1. Cancel the transfer process first.

Important
If you transferred files via Copy + Paste and get stuck, cancel the transfer and follow to speed up USB immediately.
If you used Cut + Paste to transfer data, you may lose data by canceling the process. Recover data first with EaseUS Data Recovery Wizard as shown in Method 2.

Step 2. Right-click to eject the USB drive from the taskbar.

The Bottom Line

Nowadays, most users use the USB 3.0 port with a maximum transfer speed of 400MB per second. If your computer USB port is too old (such as USB 1.1) while your USB is 3.1 or even higher level, it will highly slow down your USB speed. Switching to a new computer is a wise choice. 

When your USB transfer speed is slow, the most effective way to boost the transfer speed is in Methods 1, 2, and 4. Moreover, if you are still using USB 2.0, it's an excellent choice to switch to USB 3.0 instead.

No matter which tips you choose to fix the USB slow transfer rate error, it's essential to back up your USB file first. As for the lost USB data, EaseUS Data Recovery Wizard is always ready to help.

Some of you may have more concerns about increasing USB transfer speed. Check out the questions and find answers below:

1. Why does USB transfer speed fluctuate?

As explained above, the USB transfer speed may get infected by many factors. There are the reasons why the USB transfer speed fluctuates:

  • Read/write rate differs between computer and USB.
  • The size of the transferred files differs. (Smaller files are faster to be shared.)
  • The difference between the computer USB port and your USB type. (USB 2.0 port slows USB 3.0 flash drive transfer rate.)

2. Does the USB cable affect transfer speed?

The transfer speed of a USB is highly based on the following factors:

  1. 1. USB type - USB 3.1/3.0/2.0
  2. 2. The speed of computer RAW and hard disk speed.
  3. 3. The CPU speed.

3. How long does it take to transfer a file size of 1GB on a USB 2.0 and a USB 3.0 drive?

Accordingly, the transfer speed of 1GB file to USB 2.0 is much slower than transferring to USB 3.0:

  • Transfer 1GB files to USB 3.0 - 18 seconds;
  • Transfer 1GB files to USB 2.0 - 3 mins 18 seconds.
