A storage device includes a nonvolatile memory including a plurality of physical blocks, a communication interface connectable to a host, and a controller. The controller is configured to generate metadata of host data, which include user data and metadata of the user data, and write, in a physical block of the nonvolatile memory, the metadata of the host data, the metadata of the user data, and the user data continuously in this order, when the host data are received through the communication interface in association with a write command.

Reconstruction of address mapping in a host of a storage system

In one embodiment, a heterogeneous integrated solid state drive includes a plurality of solid state memory devices including at least one solid state memory device of a first type and at least one solid state memory device of a second type, a controller coupled to each of the plurality of solid state memory devices and an interface coupled to the controller. The controller is configured to receive at least one user-defined memory parameter and to create at least one namespace satisfying the at least one user-defined memory parameter in at least one of the plurality of solid state memory devices. In one embodiment, the at least one user-defined memory parameter is one of a group consisting of a capacity, a quality of service level, an assured number of I/O operations per second, a bandwidth, a latency, and an endurance.
