Reply to Recording my set, Best file size?

Hi peeps, I want to try to record my set toevening . Ill be playing for about 4 hours.

Question is what file size do you guys believe would be the best for not crashing the mac (MBP 2011 13" i5 2,3. 4gb 1337 ram, standard hd)? Or is there software i can run with traktor to record without using a lot of resources?
