Drilled is what it sounds like, theres holes drilled in it. You SHOULD NOT do that youreself, as simply drilling holes in the rotor, instead of them being cast or forged in will cause the rotors to crack in no time. Even originally drilled rotors are not as durable as blanks. Slotted roters, if not reffering to internally vented, are rotors with slots cut into them. Drilling and slotting do not serve to cool the rotor very much, they are done to provide a path for gasses formed while braking to escape. Cooling is a fucntion primarily of simple surface area, and the cooling fins built inbetween the rotor faces. For daily driving the best rotors are blanks that you can get from napa/autozone/schucks etc. Rotors are a wear item, and unless you road race you're car, blank rotors will suffice 99% of the time, will last longer, and will be cheaper to replace. If you want to reduce brake fade for the street, invest in some good quality street/auto-x pads like the EBC green stuff. Do not make the mistake of buying race pads, as race pads need to be hot to be effective, and daily driving they will probably land you a fender bender.
P.S. You could have found this information by searching the forum, but by writing this I can drop it in common topics ;-p.
