What do you mean by "unreliable"? Please give us more details.
If you unplug it while it is mounted, it will certainly result in a 
kernel panic. As far as FreeBSD is concerned, this is no different than 
opening the box and disconnecting your hard disk while it is running.
Other than that, I have an external USB hard disk attached to my home 
server permanently. It is on all the time, it gets mounted / unmounted 
by scripts once or twice a day. It's been running for about two years, 
and never had any problem with it. I  started using it with FreeBSD 6.x 
and is now on 7.
