Well, obviously you need to decrease size of it, by doing some
normalization than.
If some information is the same across table, stick it into separate
table, and assign id to it.
If you can send me sample of that data, I could tell you where to cut size.
I have that big databases under my wings, and that's where
normalization starts to make sens, to save space (and hence speed
things up).

For that sort of database you will need partitioning for sure.
