In practise, you should be able to vary the hard disk buffer size
independently of everything else, so you could tune it to best
performance for each machine (run some tests to see which is best?)

Also, the raw partition is going to be more reliable, because a file
could be fragmented (increasing the number of seeks), but a partition
is guaranteed to be continuous.

Maybe it's worth writing a special file system for this kind of thing.
