Format your USB Drive to NTFS with 8192 bytes of assignation, after the format, go to Device Manager, open hard disks, right-click your USB drive and go to Properties, the 2nd tab to the right (from your left), should say "Directives" (sorry about that, i have a spanish version of Windows 7) and check the "High Performance" module. That will solve your problem

I read about formatting the USB drive to NTFS in a Sandisk forum discussing this same problem. I don't feel I know what I'm doing well enough to do such a thing.

In our case, using ASUS Z97-USB 3.1 series MOBOs and observing slow and slowing USB 3.0 file transfers, we found that reinstalling the USB Driver set (eHCI, xHCI), along with the Intel Rapid Storage driver, all found on the ASUS driver install CD, corrected our speed issues quite satisfactorily. We confirmed this on two separate devices that were built up independently, fully configured with Win7 Enterprise x64. Our SAT routines (site acceptance test) now include a USB 3.0 throughput verification and driver re-install if necessary. Our file transfer test was a 24GB file moving from onboard SATA HDD to external USB 3.0 HDD - the process improved from 45+mins to 3.5 mins.

Robocopy is built into win8 and thats very fast you can get a gui to make it simpler. What can effect speed is AV as it will often scan on read and then again on write depending on file types and can slow it to a crawl

USB 2.0 has a 480 M bits per second transfer rate, or 60 M Bytes per second transfer rate. I'm confident to say that the transfer rates you have aren't related to the USB port but to the media you're using. I have different USB flash drives. The fastest transfers at 28M/s and the slowest at 3.5M/s. So the transfer isn't related to the USB transfer speed but it is related to the media you have. Multiple files always takes longer than single files. And as mentioned, Anti virus will slow it even more. So I would disable AV and compress a folder with multiple fifes before transferring. Use Winrar, Winzip or 7-zip. Edit: I have a HDD USB 3.0 dock with a SATA 2 HDD. It begins with 220 b/s transfer rate (to disk ram cache) and slows down and stabilize at 35 b/s. The results are the same if I use USB 2.0 or USB 3.0 port. The bottle neck isn't the USB. The The bottle neck is the device (SATA 2 HDD).
