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.
  • USB port is old, not compatible with a new USB drive.
  • USB drive gets full, slows down in transferring files.

So how to judge if your USB is with 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
  • USB 1.1 - 12Mbps

Ideally, USB 3.0 has a minimum transfer speed of 400MB per second while USB 2.0 is 35MB per second.

To make the file transfer speed on your USB faster, try the recommended tips as listed below one by one. You'll successfully increase the transfer speed of a USB on Windows 10/8/7 on your own.

Method 1. Change USB Port, Connect Your USB to Rear Port (for Desktop Only)

Like most users, you may connect your USB to the front ports on the desktop computer to transfer files. However, the power supply of front ports may become unstable after using for a long period. Thus, the transfer speed goes down.

To speed up your USB transfer speed immediately, you can connect your USB flash drive to one of the rear ports on your computer instead. The rear ports are soldered on the motherboard of your computer, which provides a more stable power supply to your USB.

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

Step 1. Cancel the transferring process first.

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.

Step 3. Unplug the USB drive and reconnect it to the computer's back (rear) USB port.

After this, retry to transfer your files again and check out if the transferring speed goes up. Sometimes, connecting USB or external drive to the rear port also helps to solve problems like "please insert a disk into removable disk", "external hard drive light blinking but not working", etc.

If you think it's inconvenient, you can use a USB hub that also works to speed up your USB transfer.

Method 2. Recover Data, Format to Fix Soft Bad Sectors and Speed Up USB

Wait for your computer to boot into Windows as normal and you can reconnect your USB for file transferring again. If the USB support option is previously disabled, turning it on will greatly speed up your USB transfer.

The Bottom Line

Nowadays, most users use the USB 3.0 port, which has 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. 

Honestly, when your USB transfer speed is slow, the most effective way to boost the transfer speed is in Method 1, 2, and 4. Mover, if you are still using USB 2.0, it's a good choice to switch to USB 3.0 instead.

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