So... would too much time spent seeking from blocks in one
streamed file to blocks in another to blocks in another be the
problem?  Would it (theoretically, at least) be better to have
>10 different disks/arrays, one for each file being streamed, so
that the array doesn't have to jump all over the place seeking
blocks from different files?
