  • Publication number: 20120030417
    Abstract: Embodiments of the present invention provide a RAID controller with multi PCI bus switching for a storage device of a PCI-Express (PCI-e) type that supports a low-speed data processing speed for a host. Specifically, embodiments of this invention provide a RAID controller having multiple (e.g., two or more) sets of RAID circuitry that are interconnected/coupled to on another via a PCI bus. Each set of RAID circuitry is coupled to a one or more (i.e., a set of) semiconductor storage device (SSD) memory disk units. Among other things, the SSD memory disk units and/or HDD/Flash memory units adjust a synchronization of a data signal transmitted/received between the host and a memory disk during data communications between the host and the memory disk through a PCI-Express interface and simultaneously support a high-speed data processing speed for the memory disk, thereby supporting the performance of the memory to enable high-speed processing in an existing interface environment at the maximum.
