Systems and methods are disclosed for monitoring power usage and temperature within a data storage device, and adjusting performance based on the power usage and temperature. In certain embodiments, an apparatus may comprise a data storage device (DSD) having an interface to communicate with a host device, and a circuit. The circuit may be configured to receive a first limit designation for a first operating parameter of the DSD via the interface, monitor a value of the first operating parameter of the DSD, evaluate a pending workload of operations to be performed by the DSD, estimate a future value of the first operating parameter based on the pending workload, and adjust performance of the DSD based on the future value and the first limit designation.

Drive performance, power, and temperature management

A method includes processing, via an integrated circuit, data read from a first servo wedge; processing, via the integrated circuit, data from a second servo wedge; and skipping processing data from a third servo wedge positioned between the first servo wedge and the second servo wedge.

Servo wedge skipping during track seeking

Method and apparatus for transferring speculative data in lieu of requested data in a data transfer operation. First data are transferred in response to an execution of a first pending command. Speculative data are transferred instead of second data associated with a second pending command during a next available latency period for the second data, preferably when the speculative data are adjudged as having a utility greater than a utility of the second data. The first and second commands are preferably received in a queue and a command execution algorithm identifies the second command as a next best command to be executed after execution of the first command. The above steps are preferably carried out by a controller of a data storage device.

A system for testing a bus connector comprising an electronically controlled switch operatively coupled to be controlled by a microprocessor, the system having a first input operatively coupled to receive power from an internal power supply and a second input operatively coupled to receive power from a power supply connector, and an output operatively coupled to power an output display selectively from either power supplies.

Smart tester and method for testing a bus connector

A terminating apparatus adapted to terminate a parallel small computer system interface (SCSI) disc drive or device is disclosed. The terminating apparatus includes termination circuitry adapted to terminate data/control lines of single ended (SE) SCSI devices, low voltage differential (LVD) SCSI devices and high voltage differential (HVD) SCSI devices. The terminating apparatus also includes a first connector coupled to the termination circuitry and adapted to be coupled to data/control lines of the SCSI device to be terminated through the disc drive connector.
