As far as I'm aware, a 2-drive TiVo isn't really doing anything RAID-like, it's just got an additional partition on which to store shows. Some shows will live entirely on one drive or another.
For performance reasons, sure, a "RAID 0" configuration (stripe set only, which isn't really "RAID" as there isn't anything Redundant about it, it's just, er, "AID" ) would have more available bandwidth, but I don't believe that 2 HD streams (which are compressed, after all) 720p or 1080i, plus the other relevant OS and database access, really requires more bandwidth than what can be provided by a single modern hard drive.
On that first box, it sounds like the capacity is rated on the worst-case bit rate of HD -- like DVD, your average bit rate is probably going to be lower, which should improve capacity. Personally, I think dual 120GB drives would be more than adequate for a mix of HD and SD programming, and by the time SD drops off the map drives will be less expensive. It's also not a huge increase in cost -- in quantity, probably less than $80 for the 2nd drive, plus the incremental increase for a slightly beefier power supply.
