i found it is VERY SLOW when moving files between share folders, speed at about 3.9MB/S, it seems that NAS need to read files first and then write files to another place, unlike NTFS by just changing the header of files.

My NAS: buffalo Pro Duo, No raid, just use one 2TB WD disk

Any one have tip to speed up the transfering?

You can not make the comparison you made.
The NAS is connected to your PC via Network and via an abstract
protocol (SMB/CIFS I assume due to the fact you mentioned NTFS).
This abstract protocol does not offer a "move" command.
You either connect your NAS via ISCSI or you get a HTTP based
filemanager running on your NAS or you get telnet access to your
NAS and do the move "by hand". In all three cases, the move will just
be a relocation via manipulation of a single directory entry (like you
have on your local NTFS disk).
Maybe you can also use the build-in FTP server, but I do not know if
the one supplied by Buffalo supports the "mv" command.

Using FastCopy and copying between folders on different drives (JBOD) I got transfer rates of 10.96MB/s using a 3 GB file on a LS-WXL. The program you use makes a huge difference!

EDIT: Copying the file within the same directory resulted in a slightly slower speed of 10.58MB/s.

Make sure that if you decide to use FastCopy that you turn on Main Settings\I/O Settings\Use OS buffer.
