Is onsite hard-drive destruction worth the premium over offsite?
The onsite premium buys a shorter chain of custody, not a more thorough shred. Offsite physical destruction runs about $4 to $20 per drive; onsite is quoted 20% to 100% higher plus a visit minimum near $90 to $300. Most of that premium is fixed, so small jobs pay dearly per drive and large jobs barely notice it. Decide on data classification, witness requirements, asset mix, and volume, in that order.
