How to Make USB Drives Run Faster


USB drives use write-behind caching or write-through caching when storing data to the disk. A drive with write-behind caching enabled performs faster than a drive with write-through caching enabled, but most USB drives have the former disabled, as data loss can occur. Users can enable write-behind caching in Device Manager, but must then take extra steps when disconnecting the device from the computer.

  • Click "Start." Click "Control Panel," then click "Hardware and Sound." Select "Device Manager" from beneath "Devices and Printers."

  • Expand "Disk drives." Right-click the device driver for the external USB drive.

  • Choose "Properties" from the context menu. Click the "Policies" tab. Click the radio button next to "Optimize for performance."

  • Click "OK" to improve the speed of the USB drive. Restart the computer.

Tips & Warnings

  • Do not remove the USB drive without first clicking the "Safely Remove Hardware" icon on the taskbar, as failing to do so could lead to data loss.
