Now - I've never tried this, but...

It's true that USB 2.0 is slower than an IDE/SATA controller.  USB 2.0
is limited to 480 Mbps = 60 MB/s, but in practice it will be much lower
- I have a USB 2.0 enclosure whose transfers top out at just over 200
Mbps, 25 MB/s.  IDE and SATA controllers are faster but are still only
as fast as the hard drive - 80 MB/s peak in bursts for short intervals
with the very fastest hard drives.

USB 2.0 has another strike against it - CPU usage.  It's less efficient
than Firewire and eSATA in terms of CPU usage.  However in these days of
dual-core CPUs it doesn't amount to much of a hit, but it's not 0.

With all this though, your limiting factor will be the optical drive
speed.  Even if you could rip at 52X (and you won't), it's limited to
7.8 MB/s - you'll be nowhere near saturating even poor USB 2.0
interfaces.  I suppose if you did something stupid like use the
external drive to store the temporary WAVs and the final encoded FLAC,
MP3 etc. compressed files it would be a problem as the data would be
passed back and forth repeatedly, but still, an optical drive is slow,
slow, slow.
