[Too Slow!] How to Fix USB 3.0 Transfer Speed Pretty Slow

If you have a slow USB 3.0 drive, consider updating your driver, checking for firmware updates, and ensuring that the drive is properly seated and connected to the computer. You can also try formatting the drive to its native file system, such as NTFS for Windows or HFS+ for Mac.

USB 3.0 is Slow on Windows 10

Case 1. You recently purchased a USB 3.0 thumb drive, but it's not performing as expected, with surprisingly slow read/write speeds. Specifically, you're only getting a write speed of around 50KB per second, whereas you would expect a minimum of 15-20 MB per second from a new USB 3.0 drive. This is a significant discrepancy, and you're wondering why your drive is not meeting the expected standards.

Case 2. Since updating to Windows 10, you're experiencing a significant slowdown in transfer speed when copying files to your Kingston USB 3.0 drive, with speeds barely above 0 bytes, compared to the 20-30MB/s you used to get in Windows 7.

Method One. Use the Device Manager to Optimize USB 3.0

1. Right-click on the Windows icon and select "Device Manager ".

2. In the Device Manager, expand the Disk Drives section and locate your USB device or hard drive. Right-click on it and select "Properties" from the context menu.

3. To optimize and improve your USB transfer speed, go to the Policies tab, select "Better performance", and click "OK" to confirm your choice.
After restarting your computer, you should experience significantly faster transfer speeds.

Method Two. Convert USB 3.0 from FAT32 to NTFS

If your storage device's file system is FAT32, converting it to NTFS can help speed up your USB 3.0 drive. To do this, follow the two steps below:

Part 1. Export and Restore Your Data from USB

Before converting your USB 3.0 to NTFS, it's recommended to back up your USB data to a new device to avoid data loss.
We recommend trying Qiling Data Recovery Wizard, which allows you to thoroughly scan and find existing and lost files on a USB drive, and then extract them to a safe location with just a few clicks.

Step 1. Select file types and click "Next" to start

Connect the USB drive or pen drive to your computer and launch Qiling USB data recovery software. Select the file types you want to recover and click "Next" to start the process.

Step 2. Run USB Data Recovery Software

Go to the drive labeled as an External drive, click on it, and then click "Scan" to begin searching for lost files.

Step 3. Scan and Search Lost Files on a USB Drive

Deep Data Recovery thoroughly scans a USB flash drive/pen drive to find lost data, allowing users to filter and recover specific files after the scan is complete.

Step 4. Restore All Lost Files from USB

A double-Click will allow you to preview the files. Select the target files to restore and click "Recover" to save them to a secure location on your PC or other external storage devices.

Part 2. Convert USB from FAT32 to NTFS

• Right-click on Start and select Command Prompt (Admin).
• Sign in with your Administrator account if necessary.
• Type: convert E: /fs:ntfs and hit Enter. (Replace E: with the drive letter of your USB drive.)

If the method doesn't work well, you can format your USB drive to restore it to its original state. Just remember to back up your USB drive first to avoid losing any important data.
