Slow Transfer on a USB Flash Drive b> Using a USB flash drive is a convenient way of transferring data and files from one device to another.

b>Plug your USB flash drive into your computer. Click the "Start" button and select "My Computer." Right-click the USB icon from the My Computer window and click "Properties" from the menu that comes up. Go to the "Hardware" tab and select your flash drive once you find it in the list of items. Then click the "Properties" option in this menu. Choose "Policies" tab within the Properties menu. Turn on the performance optimization option and click "OK." Click "OK" again to exit out of the Properties dialog box. Go back to the My Computer window and right-click on the USB icon. Select the "Format" option from the list of choices.

USB Flash That Is Slow and Damaged
b> USB flash drives are used to transport data between computer systems. Because it is essentially just a small hard drive, the USB device can become damaged and slow down in performance due to viruses or damaged files. To correct these problems and fix the USB flash drive, you must reformat the drive. This removes all data from the drive, returning it to its factory settings.

Plug the USB flash drive into a USB port on the computer system. Close any AutoPlay window that may load onto the screen. Click "Start" then "(My) Computer." Right-click the removable device icon that appears on the screen. Select "Format" from the pull-down menu. This loads a format options screen. Click "Yes" and the computer formats the USB flash drive, removing the damaged content and returning it to the factory settings.
ReadyBoost With a Slow Flash Drive

b>The ReadyBoost feature in Windows has the ability to increase the speed of low-RAM computers by caching program data on a flash memory device. However, the device must meet minimum performance characteristics in order for Windows to enable ReadyBoost, because ReadyBoost may not meet expectations when used on a slower device. If you still want to use ReadyBoost with your flash drive or memory card, you can make a change in the system registry to force Windows to use the device.

Insert the flash device that you would like to use for ReadyBoost. Open the Start menu, and click "Computer" to see the icon for the device. Right-click the icon for the flash device, and then click "Properties." Click the "ReadyBoost" tab at the top of the window. Clear the check from the "Stop retesting this device when I plug it in" box, and then click "OK." Remove the flash device. Open the Start menu again. Type "regedit" in the "Search programs and files" box at the bottom, and then press "Enter" to run the Registry Editor. Double-click the folders "HKEY_LOCAL_MACHINE," "SOFTWARE," "Microsoft," "Windows NT," "CurrentVersion." and "EMDMgmt." Locate and click the folder for your flash memory device under "EMDMgmt." In most cases, you can determine the correct folder because it contains the name of the device's manufacturer. Double-click the registry entry "DeviceStatus" on the right side of the window. Change the number under "Value Data" to "2" and click "OK." Double-click "ReadSpeedKBs" on the right side of the window. Change the value to "10000000" and click "OK." Repeat this process with the "WriteSpeedKBs" registry entry and close the Registry Editor. Reinsert the flash memory device, and return to the "Computer" window. Right-click the icon for the flash memory device, and then click "Properties." Click the "ReadyBoost" tab. Windows now displays an option to enable ReadyBoost on the device. You might install a usb 3 card the speeds are much faster cheap and easy to install. Hope this helps.

Flash drives are static , some times they have some proprietary
software pre-installed on them SanDisk are the only ones I know
of with added software pre-installed on them pay close attention
to the data that is being stored , since there is no registry entries
on the flash drive you can only save things such as photos , videos music and Executibles ( your programs exes ) anything else that you save came from your computers registry and can not be saved or reused without the registry . P.S. static drives
do not use the NTFS or the FAT32 configuration , those configurations are only for the operating system .
