My NDB tables seems to need approx twice the amount of disk that a compareable INNODB setup would use (see schema attached): As I understand it, 1 replica and 1 data node mean 1 fragment, but twice the disk space suggests that something is being stored twice.

If you look in the archives there is some explanation on how to compute the needed disk space (and why).

Also, considering that disk is really cheap, I wouldn't start to worry. Only with disk data (in 5.1) will it ever really matter as if you can currently afford enough RAM to have to consider how much disk space... well... err, i envy your computing budget :)
