Apparatus and methods for Cyclic Redundancy Check (CRC) error injection between storage controllers and storage devices in a storage system. A plurality of bridge devices are configured in a storage system each coupled persistently coupled to a corresponding one of the plurality of storage devices. Each bridge device may couple to one or more Serial Attached SCSI (SAS) initiators for transferring exchanges between one or more SAS initiators and the attached target storage device. Each bridge device receives parameters from a SAS initiator or an administrative client directing the bridge regarding injection of CRC errors. A log memory in each bridge may log information regarding the injected CRC errors.
