Abstract: A method of file management is disclosed for creating a virtual disk on a physical disk partition of a physical disk made of physical storage space. The virtual disk is made of virtual disk files having file system attributes. The method further includes determining a capacity of a storage space for storing a virtual disk file and formatting the virtual disk file with a particular file system format, wherein the virtual disk file has a distinct file system as stored in the physical disk partition. Additionally, the physical storage space of the physical disk is converted into a file system that supports the virtual disk. The virtual disk is configured to save nested virtual disk files, the nested virtual disk files are each configured to store additional nested virtual disk files thereby increasing security of files saved as virtual disk files in the physical disk.

Abstract: A card reader controller engine includes an interface controller responsive to information. The engine is coupled to the interface controller and is configured to compress the information before the information is to be stored in a memory card. A master interface is coupled to the engine and is further responsive to the compressed information for storage in the memory card.

Abstract: A card reader system includes a card reader controller engine in communication with a Peripheral Component Interconnect Express (PCIe) host and one or more Serial Advanced Technology Attachment (SATA) hard disk drives (HDDs). The card reader controller engine includes a PCIe controller responsive to information from a PCIe host, an engine coupled to the PCIe controller that compresses the information before the information is stored in the SATA HDDs. The card reader controller engine further includes SATA hosts coupled to the engine and responsive to the compressed information for storage in and retrieval from the SATA HDDs.

Abstract: A storage controller with Universal Flash Storage (UFS) interface includes a series bus controller responsive to information from a first externally-located host, and a microprocessor coupled to the series bus controller and responsive to the information, and one or more UFS host interfaces responsive to the output from the microprocessor and operable to generate information to one or more externally-located UFS devices. The number of externally-located UFS devices is equal to the number of UFS host interfaces, wherein the UFS host devices cause simultaneous communication of at least some of the information to the externally-located UFS devices.
