Abstract
According to an embodiment, a storage control device includes a controller, a compression condition determiner, a compressor, and an error correction encoder. The controller receives a write request for a data item and determines whether or not the wear degree of a target region in a storage device to which the data item is to be written is less than a threshold value. The compression condition determiner determines, based on the wear degree, an optimal compression condition out of compression conditions that include lossy compression. The compressor generates, based on the compression condition, compressed data. The error correction encoder subjects the data item to error correction and generates encoded data.
