you ansered your question a 250gig ard drive.
considering pricing the 120GIG hard drive is R1600 it works out cheapr to buy it with a hard drive.
however if like me you coulnt afford it the arcade is prety decent it comes with on board memory (or memory card depending on how old the model is) if 256MB or 512MB which is decent enogh for saving games, but the hard drive you can save the entire game to HDD and it loads up faster.
***choke*** What a rip-off!
