1 out of 5 eggsUmmm...

Pros: Big.

Cons: Not big enough.

Other Thoughts: Ya know, for the price of a 4 pack + $30 you can get 5 of these bad boys purchased individually. I always thought the idea of buying in bulk was to get a better price.

3 out of 5 eggsAgreed. Do the math.

Pros: Great drives, no S.M.A.R.T. errors yet.

Cons: Agreeing with the previous review. This "4" pack cost more then just buying four separate drives.

Other Thoughts: Buy them separately to avoid being ripped off.
