Subject:Re: "Car Computer" in your Vanagon?

Hard drives, a key component in any computer, try and keep themselves at
a constant speed, 3600rpm,5400 rpm or 7200rpm. Depends upon the drive.
Hard drives found in regular computers (i.e. not laptops) use 3.5"
diameter drives. They resist moving, sort of a gyro effect, if you
submit them to the bump and grind of driving, the bearings are
overloaded and they very quickly fail. Laptops generally use 2" diameter
drive. Even at the same speed, they have less rotating mass and tend to
last longer.

I have used a Dell D600 (laptop 2" drive) for years in mobile
applications without any problems or early expiry. I expect the Westy
will not be worse than any other vehicle.

I was just thinking, it's sort of wrong having a computer component that
can spin faster than a WBX :-)

Best Regards

Dave
