I have an external FireWire/USB enclosure (using the FW connection, not 
USB) with a 120GB 7200RPM WD drive in it.  I don't use it for Myth 
recordings or LiveTV, but I do use it for MythVideo rips & my MythMusic 
collection.  I'd image you'd have similar performance issues playing 
back Myth recordings as with playing back MPEG-4 .avi files (unless 
you're recording in MPEG-2, in which case the throughput requirements 
would be greater).  I've had no problems with performance.
