Just a follow-up, the most you will ever see out of a single tuner is 
around 36Mbps.  That is recording every broadcast on a single QAM256 
cable channel, which means 3 HD channels, or a dozen SD channels.  For 
pure sequential access, a modern 2TB 5400RPM drive will top out north of 
1Gbps, and won't go lower than 400Mbps.
