That's a long time, especially on a fast pentium CPU.  All I can tell is
that on my system, the wd interface doesn't seem to make the things
noticeably worse, but the ep (3com509) driver seemed to cause more data
loss.  The real problem may be somewhere else, though, because I got
FIFO overruns even when everything were supposed to be idle.
