17. A data storage system for use in a high radiation environment, comprising:
a controller board comprising a radiation-hardened storage controller; and
a storage array board coupled to the controller board, the storage array board comprising an array of storage drives, each of the storage drives comprising:
a non-radiation-hardened drive controller;
a non-radiation-hardened, NAND flash medium coupled to the controller; and
a non-radiation-hardened volatile memory coupled to the controller;
wherein the radiation-hardened storage controller provides failure-resistant data redundancy among the storage drives of the array, the radiation-hardened drive controller providing host access to the array.
