Techopedia Explains RAID 5EE

Typically, RAID level 5EE integrates the hot spare within the stripe set rather than placing it at the end of the array, as in RAID level 5E. This enables faster rebuilding of drives if a drive fails. RAID level 5EE requires a minimum of four drives to operate and supports a maximum of 16 drives in an array. The hot spare drive space, which is empty by default, is used for copying data from a failed drive.
