1. A method of operating a storage device including a nonvolatile memory device and a storage controller that is configured to control the nonvolatile memory device, the method comprising:
partitioning the nonvolatile memory device into a plurality of domains;
determining a scramble function based on a seed value of seed bits that correspond to a first portion of a plurality of address bits of a logical address among a plurality of logical addresses that are provided from a host device;
generating a scrambled domain value based on the scramble function and a domain value of domain bits that correspond to a second portion of the plurality of address bits of the logical address among the plurality of logical addresses; and
assigning a write operation that corresponds to the logical address to a domain that corresponds to the scrambled domain value among the plurality of domains.
