How to increase USB storage performance

This is a new update for Windows 7 and Windows Server to boost the speed of USB storage devices by increasing the maximum transfer size. After installing the update, you can change the maximum transfer size from 64 kilobytes (KB) up to 2 megabytes (MB) using your windows registry editor.

The hotfix is only available to the following operating systems:

  • Windows 7 and above
  • Windows 7 Service Pack 1 (SP1) and above
  • Windows Server 2008 R2
  • Windows Server 2008 R2 Service Pack 1 (SP1) and above

After installing the update here’s the Registry Hack to increase the maximum transfer length:

1. Click the Start Menu > type “regedit” in the Start Search

2. Once the registry editor is open, go to the following registry folder

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\usbstor\VVVVPPPP

3. Right-click any vacant space > New > DWORD (32-bit) Value

4. Type MaximumTransferLength and double-click to modify the value data

5. Select Decimal and type a value between 65535 and 2097120 (64k to 2M) e.g. 2000000
