|Title:||STORAGE SYSTEM AND SOLID STATE HARD DISK|
Disclosed is a storage system, comprising a controller (100) and a solid state hard disk (200). The solid state hard disk (200) includes a plurality of channels, wherein each channel is connected to a plurality of DIEs. The controller (100) is used for creating a plurality of segments in advance; choosing a first DIE from the plurality of DIEs; choosing a first segment from the plurality of segments and determining an available offset of the first segment; generating a write request, wherein the write request includes a write address, target data and the data length of the target data, with the write address including an identifier of a channel connected to the first DIE, an identifier of the first DIE, an identifier of the first segment and the available offset; and sending the write request to the solid state hard disk (200). The solid state hard disk (200) receives the write request and saves the target data according to the write address and the data length. By means of the storage system, the controller (100) can effectively use the storage space of the solid state hard disk (200).
