Fastest way to move files disk to disk?

[jesseasi]

Running unraid 4.7.

 

What is the fastest way to move terabytes of data from one drive to another drive?

 

I currently have a windows 7 machine and use teracopy to copy files - but it seems like the data then needs to be read - sent to my pc - then sent back to the array.  The fastest I can do this at is about 30mb/s per second which when moving a terabyte can take 12 hours. 

 

It seems like there should be a faster way to do maintenance like this. 

 

What am I missing?  Suggestions?

Just login via SSH and do it on the command line - using rsync is probably best (or you could even just use mv, but I'd suggest rsync is better) or you can try one of the plugins like SNAP etc

 

Drives are all in /mnt/diskx

Interesting.  using the rsync command and getting approximately the same transfer speeds.  29-31mb per second.

 

was hoping to see something in the 80mb range....

 

Used this command

 

rsync -av --stats --progress /mnt/disk#/ /mnt/disk#/

 

i like that is shows the progress and speed.  Not excited that it isn't any faster.

For parity protected disks, you are probably not going to see speeds lots higher.
