Just looking for an external hard-drive solution for editing DNxHD. I can get a PCI card that offers an external eSata connection, or one that offers firewire 800. I believe eSATA is 3gb/s and firewire 800 is 786.432 Mbit/s. As I've never quite wrapped my head around the mbits vs. mbytes, just want to be sure that eSATA really is FASTER than firewire 800 (and therefore a preferable external H-D solution).
