A storage system includes a host device including a file system configured to set a plurality of block expiration times respectively corresponding to a plurality of data blocks included in a file, and a storage device configured to store data according to control of the host device. The storage device includes a nonvolatile memory device configured to store the plurality of data blocks provided from the host device, a storage timer configured to provide a count value by counting time, and a data deletion manager. The data deletion manager generates a data deletion information table including a plurality of block deletion times based on the plurality of block expiration times provided from the host device. The data deletion manager deletes each data block of the plurality of data blocks stored in the nonvolatile memory device based on the data deletion information table and the count value.

Storage system and method of data management of the same

A storage device set is provided. The storage device set includes a reconfigurable logic chip and a storage device. The logic chip includes a retimer configured to generate an output signal by adjusting an input signal received from an external device; and an operation circuit configured to perform an operation function. The storage device includes: a first port connected to the retimer; a second port connected to the operation circuit; and a controller configured to control data transmission and reception via the first port and the second port.

Storage device set including storage device and reconfigurable logic chip, and storage system including the storage device set

A solid state disk device comprises a plurality of nonvolatile memories and a controller. The plurality of nonvolatile memories are electrically connected to a plurality of channels, respectively. The controller controls storing, erasing and reading operations of the nonvolatile memories. The controller divides input data into a number of units corresponding to a number of the plurality of channels and stores the divided input data in the nonvolatile memories through the plurality of channels.
