There are three ways to create RAID:<\/p>\n

    \n
  1. Software-RAID: Where the RAID is created by software.<\/li>\n
  2. Hardware-RAID: A special controller used to build RAID. Hardware RAID is generally faster, and does not place load on the CPU, and hardware RAID can be used with any OS<\/strong><\/li>\n
  3. FakeRAID: Since RAID hardware is very expensive, many motherboard manufacturers use multi-channel controllers with special BIOS features to perform RAID. This is a form of software RAID using special drivers, and it is not necessarily faster than true software RAID. Read\u00a0FakeRaidHowto<\/a>\u00a0for details.<\/li>\n<\/ol>\n
