Can you explain the reasoning for this?

  On a copy-on-write filesystem, modification of part of a file means fragmenting it, which carries a large performance penalty. Disabling the CoW behavior means you either cannot take snapshots of the file, or that snapshots need to duplicate the file in its entirety, but it allows for quick modification of the file in-place without fragmenting.

    Is that assuming HDDs not SSDs ?
