[mythtv-users] Using firewire or usb external drives

I've though about doing this a few times myself. I run my frontend and 
backend in the same small box and it would be an easy way to add drive 
space w/out putting another hot spinning disk in the case. Without any 
experience of running this type of setup I would suggest going firewire. 
Less overhead. www.firewire-1394.com/firewire-vs-usb.htm has a pretty 
good explanation of how the two technologies work and why firewire is 
still faster\better for something like this if you can afford it. FW 
tends to cost a little more. Also you can get 800Mbps firewire now. I'm 
not sure how many devices support this but I've seen it around. If you 
do go with this setup please post how it went and what hardware you used.
