On a lark, I just got a combo USB/Firewire external disk drive. I ran
some crude benchmarks, and I was surprised by what I found. This is
on a fairly stock -current kernel.
Firewire does around 40MB/s, while USB 2.0 maxes out at about 12MB/s.
Either amd64 is slower than i386, there has been a performance regression
between 6.2-RELEASE and whatever version of FreeBSD you're running, or you
have a rather slow external drive. I get 25MB/s from my Vantec Nexstar3
USB 2.0 enclosure:
