How to Make USB Drives Run Faster

by Ruri Ranbe

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.


  • check 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.
