I doubt this would help much really.  If you're reading sequential data
then it's pretty much as quick to keep reading as to seek to the next
chunk.
Could it hurt [performance]?  SSDs will only become more common, and
they haven't any seek penalty.
Probably not, with SSDs, but we've already got RAID10 which, if I'm not
mistaken, does pretty much what you're describing (if not, can you
provide some diagrams of what the layout you're thinking of would look
like).

Cheers,
    Robin
