Depends on whether your version of UNIX has the cpio bug.  Some machines
would take the above cpio command and use a 1,280,000 byte buffer.  Also,
the more your tape streams, the less start/stop/reverse/stop/start it
does, and it gets to live longer.  I've never had a motor go out, but
some vendors (HP) recommend that you keep it streaming as much as
possible.  Since the HP streamer costs over $3k, I've take their advice 8-).
