That was a figure I couldn't find anywhere....  
The RAID configuration was primarily for space management with some level of
redundancy (hence currently RAID 5, otherwise I would have done RAID 0)... 

So this completely answers my question.. I should be able to go to RAID 6,
without a worry of not having enough disk bandwidth... If a 6 disc RAID 6 can
handle 60MB/s (assuming 6 streams of HD content which will never happen) then I
am laughing...
