Hybrid raid controller

A hybrid RAID controller, comprising:

• a first disk mount coupled to a set of PCI-Express SSD memory disk units, the set of PCI-Express SSD memory disk units comprising a set of volatile semiconductor memories;
• a first disk monitoring unit coupled to the first disk mount for monitoring the set of PCI-Express memory disk units;
• a disk plug and play controller coupled to the first disk monitoring unit and the disk mount for controlling the first disk mount;
• a high speed host interface coupled to the first disk monitoring unit and the first disk mount for providing high-speed host interface capabilities;
• a second disk mount coupled to a set of HDD/Flash memory units;
• a second disk monitoring unit coupled to the second disk mount for monitoring the set of HDD/Flash memory units;
• a disk controller coupled to the high speed host interface, the first disk monitoring unit and the second disk monitoring unit;
• a host interface coupled to the disk controller;
• a controller unit coupled to the Hybrid RAID controller;
• a backup storage unit coupled to the controller unit which stores data of the set of PCI-Express memory disk units;
• and
• a backup control unit coupled to the controller unit which backs up data stored in the set of PCI-Express memory disk units in the backup storage unit, according to an instruction from the host or when an error occurs in the power transmitted from the host.
