rsync - Aug 2010 - Does rsync use encription also for local tranfers?

Hy everybody,
I'm using rsync to backup/synchronize folders to/from USB connected external
hard drives.
But I can't find an answer to a doubt.
Does rsync use encription also for local tranfers?
For "local transfer" I mean a transfer that doesn't go through a
network like
folders synchronization with external hard drives.
I'm asking because the speed of local transfers doesn't seem quite good
for an USB 2.0 connected hard drive.

Thanks for your help.

No.  In addition, rsync defaults to --whole-file; that is it delta-xfer is
disabled.  The effective speed per file should be similar to cp or copy,
depending on your OS.

What is the speed according to --stats?
