RAID 7 is a type of redundant array of independent disk level which includes a real-time embedded operating system and processor for increased data write / read or input / output operations and data caching capabilities. This is a non-standard RAID level that needs proprietary hardware.
Unlike the other RAID levels, RAID 7 isn’t an open industry standard. In fact, it is a trademarked marketing term owned by Storage Computer Corp used to characterize their proprietary RAID design. It is based on concepts utilized in RAID levels 3 and 4, but immensely improved to overcome some of the limitations associated with those levels. The commercial implementation integrates proprietary disk array hardware with a real-time embedded OS to handle disk drive access and data flow to host interfaces.
