You'd be surprised how much enterprises pay for Protons and Garners. For approx tripple the price (my links above) you get about 30x throughput.
But I agree, not everyone needs that speed.
For our scale at the time (destroying 10s of drives a month) it worked fine and it was a great stress reliever.
Get off a frustrating customer call? Go take 15 and take it out on the stack of drives needing destruction.
