My previous machine ran off something similar to that spec with 5mm screws (you mentioned these in an earlier post) and it was direct drive. All worked fine.
But if you want better speeds for wood then belt drive allows 1:2, also reduces resonance effects in the stepper and most important of all(!) allows the motor to be tucked away.
