[LAU] usb-2.0 harddisc

[Dragan Noveski]

hi list,
i am here on a ibm laptop with a multiface plugged into the card bus slot.
since my system harddisc slowly runs out of space, i am trying to figure 
out, what another harddisc i could use, but the only available port i 
have is an usb port.
my question is, if someone of you have already made any experiences with 
an usb harddisc?
will that be fast enough?
in the moment using a system hard disc, i am able to record 16 tracks at 
once without any problems, but since the space there is limited...
is someone of you using an usb harddisc for recording?
does anybody has an recomandation for an usb harddisc?

cheers,
doc
