I think I wil go for a Magma or a xml approach.

http://wiki.squeak.org/squeak/2665 Magma might be overkill for this amount of data. Magma needs an upgrade for recent Pharo. Chris uses it on Squeak and found maintaining it on Pharo too much work. With XML you'll need to do more work than with STON, and the objects will be less readable. Do you know https://ci.inria.fr/pharo-contribution/job/PharoForTheEnterprise/lastSuccess...
