Comment on How come it seems the transfer rate from an hard drive to usb is noticably slower? But a usb to usb is incredibly fast?

  First of all: I hate that you’re downvoted when you’re explicitly up-front about having zero expertise on this, before putting forward a completely valid hypothesis.

  Secondly: It’s very unlikely that formatting is the culprit here. I/O operations (read/write) are far slower than CPU operations, especially on spin-discs (like HDD’s), they can be several orders of magnitude slower. When you copy data, it’s basically

  • Read data (I/O)
  • Possibly do some formatting, scanning, whatever (CPU)
  • Write data (I/O)

  Whichever of these is your choke-point will determine your speed. It’s very unlikely that a pure copy operation will be choked by the CPU-bound task. Much more likely that the read/write speed of the HDD is the culprit.

    Downvote does not mean we hate you. Downvote means incorrect/unhelpful/unrelated

    it’s very unlikely

    There you have it.

      Downvote means incorrect/unhelpful/unrelated

      I’ve never before actually seen anyone argue that downvotes should be used for stuff that’s incorrect, especially when it’s not touted as being correct in the first place. Downvotes are for “the thread would be a better place without this”.

      Either way, the OP here isn’t even stating anything as fact, but openly speculating. If just can’t fathom why anyone would downvote someone for being open about their ignorance and freely speculating/hypothesizing over an answer. The only thing that does is contribute to the discussion by adding a new facet/idea people can respond to.
