This post will help Windows users who are looking for a solution to increase their read, write, copy, move, and data transfer speeds while carrying out operations from their Windows computer to a USB and vice versa. Microsoft has released an update that will now allow you to increase the maximum transfer size of USB storage devices in Windows.
Increase maximum USB data transfer size in Windows
In Windows 7, by default has set the maximum USB transfer size for USB storage devices at 64 KB. This default setting is configured in the USB port driver (Usbport.sys) in Windows 7 and Windows Server 2008 R2.
If you want to increase the maximum USB transfer size to as much as 2 megabytes (MB), you can apply this new Hotfix, which Microsoft has released.
For some USB storage devices, performance can be improved by increasing the maximum USB transfer size beyond the default setting of 64 KB. This update is supported when the hardware vendor provides a device information file (.inf) to set this value for USB storage devices.
You may have to restart the PC after installing the update available at KB2581464.
After you have installed this update, to increase the maximum transfer size of USB storage devices, open the Registry Editor and navigate to the following subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\usbstor\VVVVPPPP
Notes
- VVVV represents device descriptor idVendor in hexadecimal.
- PPPP represents device descriptor idProduct in hexadecimal.
Click Edit > New > DWORDValue. Type MaximumTransferLength and hit Enter. Next, click Edit > Modify.
In the Value data box, type any value between 64 KB and 2 MB range. For example, to increase it to 2 MB, select Decimal and type 2097120. Exit Registry Editor.
Let us know if this works for you.
Ok, all my USB flash drives use the default driver, does that mean I won’t get better speed with this update installed?
Doesn’t work on windows 7 64 bit.:(
It don’t work in 64 versions or the fix need a fix for itself because the HKLMSYSTEMCurrentControlSetControlusbstorVVVVPPPP is not appearing the registry, the VVVVPPPP part.
