To improve the write performance for USB storage devices in general follow these steps:
1) Open the IGEL Setup or your UMS Profile and go to System->Registry
2) Disable devices.autofs.sync_option
Note: This will not work for “true” USB Redirection (View, XenDesktop, RemoteFX, Fabulatech and so on) but it will improve the general performance for RDP, ICA and other drive mappings. Test in advance!
