This is an Microsoft Windows 7 or Server 2008 R2 update that may improve performance of USB transfers. Now they do say, "for some":
How? Well per Microsoft:
Now, you do need to read the Hotfix article, here > An update to increase the maximum transfer size of USB storage devices in Windows 7 or in Windows Server 2008 R2
Now, after you apply this hotfix, you will need to do some registry editing.
So, back up your registry before proceeding. And, also, you do this at your own risk; as always... anything can go wrong at anytime, even in the most perfect circumstances.
This registry edit is, also, covered in the hotfix:
After you install this update, to increase the maximum transfer size of USB storage devices, follow these steps:
1.Click Start, type regedit in the Start Search box, and then press Enter.
2.Locate and then click the following registry subkey:
3.HKLM\SYSTEM\CurrentControlSet\Control\usbstor\VVVV PPPP
4.Click Edit, point to New, and then click DWORDValue.
5.Type MaximumTransferLength, and then press Enter.
6.Click Edit, and then click Modify.
7.In the Value data box, type a value to specify the maximum transfer size between 64KB and 2MB. For example, you select Decimal and type a value between 65535 (64K) and 2097120 (2M).
8.Exit Registry Editor.
Notes
VVVV represents device descriptor idVendor in hexadecimal.
PPPP represents device descriptor idProduct in hexadecimal.
