fastest file copy for encrypted data?

Hi,

What is the fastest file copy method between an encrypted external HD and the bubba3 ?

I've got 1TB of cryptsetup encrypted data on an external HD. If I mount the drive on the b3 by USB, the copy process is extremely slow (11MB/s !!). I guess this is because of encryption.

So I tried multiple methods. The best I could do (20MB/s) is to
- use the b3 as a DHCP server
- connect the LAN internet port to a laptop with a RJ45 cable
- nfs mount the b3 on the laptop
- mount the encrypted HD on the laptop
- copy files.

Is there anything better? I'm ont even convinced that a non-encrypted usb drive mounted on the b3 will be much faster.

Thx
Cyril

Usb is slow, its just simple as that. Why not get an esta adaptor to connect the drive to the b3 over a fast bus?

You're talking about the e-sata entry in the back of the b3 ?

Is it posible to mount an encrypted drive on the e-sata slot ? I've no idea. I guess you get a /dev/something and from there you can mount manually. I'll try. Thx!
