Karos online question

Hey all. i'm trying to find out the hard disk space required for KAROS online.

Personally I am a WAR player moving to RIFT with my guild, Ars nova (of which I am an officer) but A friend of mine wanted help in Karos and I feel obliged to help, but Can't find the info on the Karos website.

Could someone please tell me what amount of hard disk space I will need?

Thanks,

Rak
