There is a reason for this sort of gear
Time is money.
As an example, we have a couple thousand PCs that are dumped each year due to lifecycle replacement. Yes, these are perfectly good PCs that could be wiped and loaded with (whatever) and donated .. but THAT COSTS MONEY. Loosing even ONE hard drive with data on it puts us in the newspaper, hence the policy is :
No data storage device leaves intact, ever.
We have the guys in facilities run them through a giant metal bandsaw, and that's BEFORE they go to be shredded/recycled (which, ironically, we pay THEM for, despite the fact that we're talking about tons of aluminum/steel/whatever .. but they won't burn off the insulation out back like JimBob either).
The reason you don't use .45ACP or sledgehammers is one of liability. Before the bandsaw method we used sledgehammers until some idiot hurt himself. When somebody looses a finger due to stupidity we'll probably buy one of these.
