My question is what impact will adding these new more powerful data nodes

twice as fast the other?
I'd assumed the situation would be analogous to using memory DIMMs of
different frequencies on the same motherboard - whereby memory performance
is limited to that of the frequency of the 'slowest' DIMM - but I'm
struggling to find on the WWW any practical guidance or experiences of
scaling-out a MySQL Cluster further down the line.
Things will cope fine - and if you just use data on the faster machine,
it'll be faster than before!
Of course, "global" performance is going to be limited by the slowest
point.
