Abstract
Disclosed are a solid state drive and a write operation method. The solid state drive comprises: a controller, receiving write data from outside and comprising a first cache unit for storing the write data; a Flash memory, receiving the write data sent by the first cache unit according to a first instruction of the controller; a second cache unit, storing the write data from the first cache unit as backup data, and sending the backup data to the Flash memory according to a second instruction of the controller. The second instruction is obtained after the write data fails to be written into the Flash memory under the first instruction, so that the backup data can continue to be called if write operation fails. By combining advantages of the first and second cache units, efficiency and quality of write operations are improved and bandwidth requirements are lowered.
