Describe the three types of disk provisioning, particularly the difference between thick and thin.

Thick provisioned uses the entire space you defined at the point of creation. Thin provisioned is more space conscious and only uses as much of the defined space as it needs. Thick has two versions, eager-zeroed and lazy-zeroed: Eager is slower at creation as it places a 0 in every bit of the allocated space.
