Im planning on buying the new iMac 27 inch Haswell with a 3TB Fusion Drive but I wanted to know if the SSD is located seperately from the Hard drive is it a PCIe SSD with a regular 3TB SSD or is it a Hybrid drive with a SSD built in because Ive seen the teardown on ifixit and saw a empty PCIe slot. If the drive is a Hybrid drive is it possible to install a SSD on my own and also have the fusion drive?
