A data storage caching architecture supports using native local memory such as host-based RAM, and if available, Solid State Disk (SSD) memory for storing pre-cache delta-compression based delta, reference, and independent data by exploiting content locality, temporal locality, and spatial locality of data accesses to primary (e.g. disk-based) storage. The architecture makes excellent use of the physical properties of the different types of memory available (fast r/w RAM, low cost fast read SSD, etc) by applying algorithms to determine what types of data to store in each type of memory. Algorithms include similarity detection, delta compression, least popularly used cache management, conservative insertion and promotion cache replacement, and the like.

A tape drive emulator (30) is between a host computer (40) and a removable disk drive (22) and appears to the host computer 40 as a sequential storage system, e.g., a tape drive. However, the tape drive emulator (30) processes the data obtained from or applied to host computer 40 so that the data can be communicated to removable disk drive 22 in a manner compatible with a conventional removable disk drive. Yet in so doing, tape drive emulator 30 imposes on the data (1) an data organization, imperceptible to disk drive 22, for rendering the data expressable and locatable in a tape drive format, and (2) an additional degree of error correction that provides enhanced data integrity necessary for data backup/restore operations.

Systems and techniques describe a collaborative road user safety service that interacts with a coordinating set of collaborative safety devices belonging to road users in order to interchange reliable information about road safety. A distributed ledger/blockchain is utilized in connection with the service to coordinate data exchange between collaborative safety device users and provide data subscribers with reliable safety data that can be used to automate ancillary technical processes. Collaborative safety devices can alert members to road safety issues and be used to confirm information about road safety by collecting sensor and telemetry data. Data subscribers can receive aggregated, anonymized, de-anonymized, or specific road user data pertaining to road users and define the terms of incentives to road users that “self-revise” if a road user's vehicle is a target vehicle via smart contract interfaces. Cryptographic token can be transferred to incentivize data sharing, accuracy, and safe road behaviors.

The reliability of data is significantly increased without considerably increasing costs by performing minor data corrections within an information storage device and performing major error corrections in an information processing device. When a request to transfer user data for reading is issued from an information processing device, a control circuit transfers the user data and management data to an error detection circuit, which checks the user data for errors. If the user data contains no error, the control circuit notifies the information processing device that the user data can be transferred, and transfers it to the information processing device. If the user data contains errors, an X count error position and correction data calculation circuit uses the user data and the management data to calculate correction locations and correction data, and judges whether the correction locations are correctable. If uncorrectable (there are more correction locations than X locations), the control circuit notifies the information processing device that the user data is uncorrectable, and then transfers the user data and the management data to the information processing device.
