A cascaded RAID controller includes a master RAID 1 controller having a control level and M slave RAID 1 controllers, where M is an integer greater than or equal to 1. Each of the M+1 RAID 1 controllers is configured respectively to have three ports, including a primary port configured to communicate bi-directionally with computer hardware having a higher control level than that of the respective one of the M+1 RAID 1 controllers and including two secondary ports. The cascaded RAID controller is configured to provide connections to a total of M+2 memory devices, and configured to record the same information on each of the M+2 memory devices to create M+2 identical copies of the information. A process for initializing a cascaded RAID controller is also described.
