My laptop gets 27.1 MB\/sec. (sequential) write, 41 MB\/sec. sequential read, and 29.9 MB\/sec. random reads. This was on a 1GB file; it wanted to do a ~4 GB file, but I really didn&#8217;t feel like spending the time. I suspect the goal is to make sure that it&#8217;s not being &#8220;fooled&#8221; by caching, but I figured 1GB was sufficient for that. Some of the results show read speeds of 600+ MB\/sec., which is most definitely coming from cache.
