Bob:

You're missing something obvious here.  You capture to a fast RAID,  
which only needs to be big enough for a day's shooting.  Then you  
dump data to either a pair of LTO-3 tapes or a pair of drives, then  
wipe the RAID and use it again.

You don't use the cheap drives for capture, just for transport and  
storage.  You'll need to dump the data to another RAID to work with  
it, of course.
