I've tried many hard drive enclosures and I think this is the best option to protect your hard drive. It is stuffed very generously and the disc does not slip into it. I haven't tested any of my drives for drops (!), but they have withstood the knocks and bumps of the daily commute from home to the office. The only downside is that the case is a bit larger than others, but that's a small price to pay for security. Highly recommended!
