Large volume of data in PCA cube and ODS

Hi,

I am loading an ODS which eventually feeds another Cube.For 8 months of 2005 I already have 240 mil records in the ODS and 360 mil records in the Cube.I still have to load another 4 months of data.Do u think it is still advisable to load data into these and can some one tell me how much data is advisable to load and the pros and cons of loading such data.

Regards,

Kal
