Well if we are proposing new devices I'll like to have
stripping on the fs, or even raid.  

fs has interleave and concat disks but the
max. performance is limited by one disk. It does not
break a block in pieces and does the IO in parallel.

I don't think it's applicable to the juke box, 
a lot of noise in the machine room :-)
