Howto: Fix Slow USB 2.0 file transfer on Windows XP
August 11th 2010
USB storage devices can be optimized for either quick removal or performance. If optimized for quick removal, data transfer can potentially be reduced to a crawl.
To optimize your USB drive for performance:
1.Right click on the USB drive and select properties
2.Select the Hardware tab
3.Under All Disk Drives, highlight your USB drive and select Properties
4.Select the Policies tab and select Optimize for performance.
5.Press OK twice, and your transfer speeds should increase dramatically
Note that when your drive is optimized for performance you'll need to use the Safely Remove Hardware icon in the taskbar to eject the drive - otherwise you'll risk corrupting your data by just removing the drive from the port.
