Honestly, unless you're doing durability testing on a vehicle and driving it consistently over washboard roads, you're not going to create enough vibration for there to be a concern.
Hard braking is
NOTHING, as far as force is concerned.
If you read the thread, one user totaled two cars and the hard drive still functions like clockwork. A crash that will total a car is more force than the braking from even the fastest race cars.
Again...
DON'T WORRY SO MUCH ABOUT IT!
Mount all your hardware securely and you'll be fine.
