When I am moving a file (movie) from one share to another (all the drives are on the NAS) I am only seeing a 16.1 MB/second rate.. I am using Hitachi 4TB 5400rpm drives and this seems very slow to me. Is there something I can do to speed this up?

Are you moving them directly on the Unraid server (telnet in, use the mv command) or via a client machine (for example using Windows Explorer)?

Or instead of using mv you can use mc which gives you an explorer type view.

I have been doing it from my win7 NUC which is connected to the NAS via my Cisco gigabit switch.

Have you previously seen speeds faster than this? By going through your Windows machine your spinning up a disk on Unraid to read from it, sending it across the network, sending it back again, and writing to disk again twice (once for the copy and once for the parity). That's a lot of overhead.  Additionally, depending on how your shares are set-up and how full your disks are, Unraid might actually be reading and writing to the same physical disk, which will cause performance loss as the drive head will be constantly moving from reading / writing.

 

Honestly, if you're moving stuff around Unraid, you're better off doing it directly on the server.
