Experiencing sluggish USB data transfers lately? USB drives are a widely used method for exchanging data between devices. Their compactness and portability make them an excellent choice for on-the-go storage. It's not uncommon for USB data transfer speeds to fall short of the manufacturer's claims, leading to frustration and wasted time. Factors such as the USB type, age, and connection port can contribute to slower transfers, but your system might also be part of the issue.

If your USB data transfers have become painstakingly slow, this article offers effective solutions to accelerate the performance of your USB drives.

Why is my USB flash drive so slow?

Typically, USB transfer speeds will slow significantly if you are experiencing one or more of the following issues:

1. The USB port's power supply is unstable.
2. Bad sectors.
3. The USB file system is sluggish when transmitting large data.
4. The USB port is outdated and incompatible with a new USB disk.
5. When a USB disk is full, file transfers become slower.

And if you have any tool that can test the speed of your USB drive, you can check the following info to estimate the status of your USB:

◤ USB 3.1 – 10GBps
◤ USB 3.0 – 5GBps
◤ USB 2.1 – 480Mbps
◤ USB 1.1 – 12Mbps

Besides the changes in speed, your USB might also have the issues like a never-ending transferring process. If your USB fulfills one of the aforementioned requirements, such as freezing when transferring files or failing to reach its average speed, it has a sluggish data transfer rate.

And if you have another PC, you can try your USB on that machine if the rear port also slows.

Way 2. Temporarily turn Off Windows Security

Occasionally, Windows security and real-time protection can impose limitations on transfer rates. This situation commonly arises during the initial USB connection or when the connected device has previously encountered malware. The improper configuration might cause Windows to incorrectly label it as a potential threat, leading to consistent slowdowns or even halts in processing.

Consequently, temporarily disabling Windows security becomes crucial to prevent any interference with your data transfer speed.
