[Soekris] net5501 USB port speed?

[Malcolm Herbert]

I'm wondering about the usual speed of the net5501 USB port, as I seem
to get no better than about 700KB/s to an attached external disk.

I haven't yet worked out where the bottleneck is, but a 250GB RAID
mirror is expected to take 4 days to sync, which seems to be a little 
too long to me ... it also seems to pound the CPU pretty hard when
I do any sustained USB traffic ... 

Has anyone else seen this transfer rate from their net5501?  Is it 
just a case of a crappy USB "2" disk caddy?

If the USB port isn't really useable for external disks, what options
would I have to get some sort of mounting bracket for a second disk
inside the box - presumably a SATA 2.5in disk of the same type?

Regards,
Malcolm
