I don't know about Ubuntu, but apparently Windows Vista and 7 have something very similar. http://en.wikipedia.org/wiki/ReadyBoost http://en.wikipedia.org/wiki/

  Not even sorta similar, "ReadyBoost" is a cache "Fusion Drive" provides the union of space. They are in the same vein of "hide the slowness of rotational media" but that is a pretty huge vein.

    In the Fusion Drive example, 3TB of hard drive is combined with 128GB of flash. The union of space is 3.125 TB, compared to the 3TB you would get with a cache. That's just a 4% increase in space that the Fusion Drive gives you over what a cache would give you. You can call it whatever you want, but I'm going to call them similar.

      And "just" a 32x increase in flash size.

  Not ReadyBoost, but ReadyDrive: http://en.wikipedia.org/wiki/ReadyDrive#ReadyDrive http://en.wikipedia.org/wiki/ReadyDrive#ReadyDrive
