Assuming you are talking about computer punch cards... PRO: They last longer than other media. They don't lose data when exposed to a magnetic field. CON: They are slow to load. The data density is low (you'd need a truck to carry Microsoft Office on punch cards), they are susceptible to being damaged by water and anything else that destroys paper, they can get accidentally shuffled, they take lots of storage space, nobody has card readers anymore.
