Frequent enough that I've seen it twice on different arrays. The reason for this is that a drive failure can be caused by an external factor (usually multiple drives fed by the same broken power supply, but not yet so broken that it goes off-line).

I didn't say they don't happen.
They're just so rare that the difference between ~6h rebuilds with 4T spindles versus 15h rebuilds with 10T spindles simply doesn't matter. Any homeopathic advantage of slightly faster rebuilds is dwarfed by the benefits of higher density (less hardware per capacity).
