  1. an irrelevance? do you know what an irrelevance is?

    Never get's old watching actuators.
  3. The combined life of my 4 hard drives that are running 24/7 is according to S.M.A.R.T. data 16.6 years old. Eat that SSD, you got the speed, we got the reliability.

    Yet my Samsung F3 only lasted 11 months :(
  5. You shouldn't eat SSDs, you'll break your teeth (I keep posting this joke, the humor police keep deleting it - does anyone know why? it certainly isn't offensive!)

    Because it's a terrible joke.
     
  7. Stop beating up the guest!

    Electrons in an electric field flowing along a copper wire can move incredibly slowly. Please see here

    In this example the electrons move about 1m an hour - I can certianly walk that fast.

    Did no-one read Doctor John's post above - I'm sure he's right, and what he said covers ALL these scenarii, so we can all stop arguing! ;)
  9. Make no mistake, electrons in a conductor move fast, about 0.5% the speed of light. What they don't do is consistently and coherently move in the same direction very quickly. They bounce around and scatter so much that their net motion is very small, around the 1 meter per hour figure quote above.

    Absolutely, so the average velocity of a bunch of electrons can approach zero, but the individuals are zooming and bouncing off each other & atoms in the conductor (which is why cables get warm!). Nice one, Guest (y)

    Probably a defective one, have a samsung myself (hdtune reports 1100 days in function, that means somwhere around 3 years and smth always ON) and still this model was a Spinpoint.
