Microsoft has released a new update for Windows 7 and Server 2008 R2 users which adds a new feature to these operating systems.
This new update allows you to increase maximum transfer size of USB storage devices in Windows which will help in improving performance of USB devices. After you install this update, you can increase the maximum transfer size from 64 kilobytes (KB) to 2 megabytes (MB) to improve USB performance.
You just need to follow these simple steps to improve USB storage devices performance in Windows 7:
1. First download and install the update using following link:
2. Now type regedit in RUN or startmenu searchbox and press Enter. It'll open Registry Editor.
3. Now go to following key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\usbstor
4. Under usbstor key, create a new key VVVVPPPP so the final path would be:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\usbstor\VVVVPPPP
5. Now in right-side pane, create a new DWORD value MaximumTransferLength
6. Double-click on this new DWORD value, set Base to Decimal and set Value data to 2097120
That's it. Restart your system and get ready to enjoy improved USB storage devices performance in Windows 7 and Server 2008 R2.
PS: If you want a ready-made registry script to do the task automatically, download following ZIP file, extract it and run the extracted REG file. It'll ask for confirmation, accept it:

As with ALL registry hacks, do not even consider it unless you have a backup of your registry and know how to use it. System Restore should also help if it "blows up."
Fairly safe update though. Pretty much the worst thing that could happen is you might corrupt some of the data you are copying.
