A 1" drill bit drilled 1/4" deep, is the same area as 1/4" drill bit drilled 1" deep.
:bull:Bear Rider said:No. It's 4 times the volume. The volume is proportional to the square of the diameters multiplied by the depth.

Volume of a hole;
Diameter x pi` x Depth
1 x 3.14159 x .250 = 0.7853975
.250 x 3.14159 x 1 = 0.7853975
