摘要： A storage device includes: a plurality of non-volatile memory devices; a buffer configured to store user data and event data of a vehicle; a parity generating circuit configured to generate parity data; and a controller configured to: generate at least one user data segment corresponding to at least one first segment from a plurality of first segments based on the user data, generate, based on predetermined information generated in a state in which at least one user data segment is generated, at least one event data segment based on the event data corresponding to at least one first segment from the plurality of first segments that is different from the first segment corresponding to the user data segment, and store a stripe comprising the at least one user data segment, the at least one event data segment, and the parity data in the plurality of non-volatile memory devices.

摘要： In a method of writing data in a storage device, a data write request is received from a host device. Spatial information is received from a spatial sensor included in the storage device based on the data write request. A logical storage area management table is updated based on the data write request and the spatial information such that target data to be stored is written into a target storage area corresponding to the spatial information among a plurality of logical storage areas. A program command and the target data are transmitted to a nonvolatile memory such that the target data is programmed into a physical storage area in the nonvolatile memory corresponding to the target storage area.
