Data storage device having multiple solid state drives for data duplication, and data processing system including the same

摘要

A data storage device includes a plurality of solid state disks (SSDs) and a controller configured to control the SSDs. The controller respectively writes a first data segment and duplicated data of the first data segment to first-type memories of two respective SSDs among the plurality of SSDs in response to a first write request of a host, respectively writes a second data segment and duplicated data of the second data segment to first-type memories of two respective SSDs among the plurality of SSDs in response to a second write request of the host, and writes parity data generated based on the duplicated data to a first-type memory or a second-type memory of a parity SSD. The data storage device may be included in a data processing system.
