Fixing slow USB 3.0 data transfer speeds



RECOMMENDED: Click here to fix Windows errors and optimize system performance.

If you just bought a new USB 3.0 drive (or hard drive) and are experiencing surprisingly slow read/write speeds, read on for a quick fix! A USB 3.0 drive should offer a write speed of at least 15-20 MB per second, if not more. But Windows is not properly configured to achieve these speeds by default.

USB drives are commonly used on computers to transfer files such as photos, videos, documents, etc. When transferring large amounts of data, the transfer speed is very important.

However, sometimes the slow transfer of data via USB can be annoying. No one wants to wait tens of minutes for a data transfer, especially when you need the data now or have important things to do.

For faster file transfer between the PC and the USB flash drive, speed up the data transfer via USB. How can I speed up the data transfer via USB? Tell us about these methods in the next section.

What causes USB 3.0’s slow data transfer rate

The slow transfer speeds of USB 3.0 are definitely an annoying scenario, especially when you need to transfer a large file. The transfer speed usually depends on the reading speed of the source device, the transfer speed of the USB port and the writing speed of the destination device. However, there are other problems you can solve to achieve maximum file transfer speed.

Outdated drivers: USB 3.0 in Windows 10 is expected to offer file transfer speeds of at least 100-200 MB per second. If this is not the case, it may be due to outdated drivers.

Updates are installed automatically when the operating system is updated regularly. Otherwise, we can manually check for updates and install them.

Faulty hard drive: Another reason for USB-3’s slow data transfer rate may be a defective hard drive. Over time, hard drives can accumulate a large number of unnecessary and unwanted files, which can lead to decreased performance. Defective sectors and corrupt system files are also major factors in poor performance.

Wrong USB port : Make sure the USB storage device is properly connected to the USB port and is not damaged. A poor connection can result in slow data transfer and data loss during transfer. Make sure the USB device is securely connected to the USB port.

The computer is running an older version of Windows : Another reason for low data transfer rates is that the operating system is not updated. First, check for Windows updates using the search bar on your desktop. It scans for a few minutes and tells you if any updates are available. If updates appear, install them and restart the computer for the best possible speed.
