Storage device performing self-diagnosis and storage system including same

The invention discloses a storage device performing self-diagnosis and a storage system including the same. The storage device configured to be connected to a redundant array of inexpensive disks (RAID) controller includes a plurality of non-volatile memories. The memory controller is configured to control the plurality of non-volatile memories to store data allocated by the RAID controller based on a RAID configuration signal received from the RAID controller. The memory controller is configured to perform a self-diagnosis on the plurality of non-volatile memories when the RAID configuration signal is deactivated to determine whether at least one of the plurality of non-volatile memories has an uncorrectable error. 公开了执行自诊断的存储装置和包括该存储装置的存储系统。所述被配置为连接到廉价磁盘冗余阵列(RAID)控制器的存储装置包括多个非易失性存储器。存储器控制器被配置为：基于从RAID控制器接收的RAID配置信号而控制所述多个非易失性存储器，以存储由RAID控制器分配的数据。存储器控制器被配置为：在RAID配置信号被去激活时，对所述多个非易失性存储器执行自诊断，以确定所述多个非易失性存储器中的至少一个是否具有不可校正的错误。
