A data storage system for managing an operation of a solid-state device (SSD) includes the SSD, an adaptor coupled to the SSD via a first bus protocol and including a non-volatile memory storing a power configuration table. The protocol converter is configured to: couple to the adaptor using the first bus protocol, convert first signals of the first bus protocol to second signals for a second bus protocol, and couple to a host using the second bus protocol. The power configuration table includes power profiles for the SSD each corresponding to an interface type for the second bus protocol. The protocol converter is further configured to: determine an interface type of the second bus protocol, read the power configuration table from the non-volatile memory to determine a power profile corresponding to the determined interface type, and cause the SSD to operate using the determined power profile.

Systems and methods are disclosed for providing an indication of the data transfer protocol that is operative during a data transfer operation between a data storage device capable of supporting a plurality of data transfer protocols and a host computer. A protocol controller of the data storage device is configured to determine a data transfer protocol based on a data cable used and to generate a selector signal used to provide the indication.

Systems and methods are disclosed for replicating data across data storage devices of a logical volume. A data storage system may create a logical volume by grouping the multiple data storage devices together. The data storage devices may be external standalone data storage devices. The data storage system may also replicate data across the logical volume.

Systems and methods are disclosed for determining an input voltage level of an input voltage received by a connection cable. A monitoring component may determine whether the input voltage level matches one of a plurality of voltage levels. The connection cable may include an indicator component that may indicate which of the plurality of voltage levels matches the input voltage level.

A device may comprise data storage, a power manager and a bridge device that is coupled to the data storage and to the power manager, and configured to bridge between at least a first data protocol and at least a second data protocol. The bridge device may comprise a UART, a first clock, a second clock and bridge device firmware configured to cause the bridge device to selectively configure the UART for communication using the first clock or the second clock. The power manager may be configured to, when a command is to be issued to the data storage when the bridge device firmware has configured the UART for communication using the first clock, assert a signal that causes the bridge device firmware to stop configuring the UART for communication using the first clock and to configure the UART for communication using the second clock.

A connector may include at least one power conductor configured to supply power to an electronic device; at least one ground conductor to supply a ground to the electronic device; at least one data conductor configured to carry data to or from the electronic device; optionally, one or more connector orientation conductors; a first magnet on a first side of the connector; and a second magnet on a second side of the connector. The connector may be reversible to be magnetically-connectable to a mating connector in a first orientation and in a second orientation that is 180 degrees from the first orientation. The connector may be operative to carry data and power to and/or from the mating connector when connected to the mating connector in the first orientation or in the second orientation.

A controller for a DC motor comprises an output switching element configured to couple to the DC motor; an input switching element coupled to the output switching element; a pulse width modulated (PWM) signal coupled to a control terminal of the input switching element and a supply voltage applied to the output switching element. A resistive-capacitive (RC) network may be coupled to a control terminal of the output switching element, with the RC network being configured to integrate the PWM signal into a DC voltage. A first resistive network may be configured to set a bias for the output switching element when the input switching element is turned off, and a second resistive network may be configured to set the bias for the output switching element when the input switching element is turned on, such that the controller is effective to provide zero-to-full supply voltage control to the DC motor.
