So, your new partition will not run as fast as a Fusion drive. IMPORTANT NOTE 2: If you have a Fusion drive, the SSD portion of the Fusion drive is always associated with the first partition. What this technique is specifically designed for is running multiple operating systems on the same computer system. If you need more space, buying an external hard drive is a far better option.
