A system that includes a first data storage element actuated by a first electric motor. The system also includes a second data storage element actuated by a second electric motor. An electrical connector assembly transfers electrical energy from a back electromotive force generated in the first electric motor, by movement of the first data storage element, to the second electric motor to thereby energize the second electric motor.

An apparatus with a slider body, a laser diode, and an isolator element. The slider body has an optical pathway extending therealong. The laser diode is configured to emit light along the optical pathway. The isolator element is disposed in the optical pathway to reduce optical feedback along the optical pathway back to the laser diode. In some embodiments, the isolator element is disposed in the optical pathway between the laser diode and the slider body.


Examples of selective enablement of operating modes or features of a storage system via host transfer rate detection are disclosed. In one example implementation according to aspects of the present disclosure, a storage device includes an interface configured to couple the storage device to a computing host indirectly via an intermediate fabric; and a storage controller configured to determine whether a nominal data transfer rate of the interface across the intermediate fabric is at or above a predetermined threshold, and selectively enable coalescing of status information that is to be returned to the computing host via status combining across multiple host requests responsive to it being determined that the nominal data transfer rate is at or above the predetermined threshold.

Methods of securely authenticating a host to a storage system are provided. A series of authentication sessions are illustratively performed. Each of the authentication sessions includes the host transmitting an authentication request to the storage system. The storage system authenticates the host based at least in part upon a content of the authentication request. After each successful authentication of the host to the storage system, an encryption key that was utilized in encrypting the authentication request that was transmitted to the storage system is deleted. After each encryption key deletion, a new encryption key that is different than the previous key is optionally stored and is utilized in the next authentication session.
