Hello everybody,

I was performing this task always with the Superflexible FileSynchronizer (http://www.superflexible.com/) but I thought there has to be a way to make it faster.

I have a HP ProCurve 2810-24G which I think supports the trunking of ports. So it should be possible to hook up both NAS with each two 1GBit Links to the Switch to have a total bandwidth of 2GBit from NAS to NAS. The NAS Support it one is a QNap TS-EC1279U-RP (Product Link) the other one is a QNap TS-459 Pro+ Product Link).

Internal Speed of the two NAS should be good enough:
QNap TS-EC1279U-RP
[~] # hdparm -tT /dev/md0

/dev/md0:
 Timing cached reads:   25096 MB in  2.00 seconds = 12568.74 MB/sec
 Timing buffered disk reads:  1646 MB in  3.00 seconds = 548.59 MB/sec
QNap TS-459 Pro+
[~] # hdparm -tT /dev/md0

/dev/md0:
 Timing cached reads:   3460 MB in  2.00 seconds = 1730.94 MB/sec
 Timing buffered disk reads:  888 MB in  3.00 seconds = 295.85 MB/sec

Now how do I transfer this large amount of data from one NAS to the other with the best performance?

Thanks a lot for your help guys
