Abstract: 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.

Abstract: A method is provided to operate a storage device including a storage controller and a plurality of nonvolatile memory devices. A plurality of original data blocks are received at the storage controller from a host. An original parity block is generated based on the original data blocks. The original data blocks and the original parity block are stored in respective ones of the nonvolatile memory devices, wherein a first original data block of the original data blocks is stored in a first one of the nonvolatile memory devices, and wherein the original parity block is stored in a second one of the nonvolatile memory devices. A new data block corresponding to the first original data block is received at the storage controller from the host after storing the original data blocks and the original parity block. The new data block is stored in the first nonvolatile memory device. A new parity block is generated at the second nonvolatile memory device based on the original parity block and based on differences between the first original data block and the new data block.

Abstract: An electronic device includes a host device and a plurality of storage devices. The host device includes a processor and a baseboard management controller (BMC). Each of the plurality of storage devices includes a storage controller and a micro controller unit (MCU). The processor and the storage controller support in-band communication, and the BMC and the MCU support out-of-band communication. The BMC receives monitoring data from the MCU of each of the plurality of storage devices based on the out-of-band communication. The processor allocates a first workload among one or more workloads to a first storage device among the plurality of storage devices, based on a monitoring data set including the monitoring data. The first storage device executes the first workload based on the in-band communication.
