I am hoping someone can help I have a pc which I have made into a Media Server Running Freenas and it works really well anyway I have just added 2 more HDD's to the system, so I now have 2 500GB drives and 2 1.5TB Drive, I have configured it into a raid 5. my problem is that the total space is 4TB but it is only giving me 1.3TB of usable space, Am I wrong in thinking that it should not need to use 2.7TB for Rundentcy, I thought I would of had at least 2TB or usable space. Or will I need 4 identical drives, hope someone can help
