A method includes receiving, at an interface of a storage device and from a host device, an electrical signal representative of data. The storage device includes a mass storage device. The method also includes splitting, at the interface, the electrical signal representative of the data into a first data stream and a second data stream, wherein the first data stream is identical to the second data stream. The method also includes sending, from the interface and to a controller of the storage device, the first data stream; and sending, from the interface and to an analyzer integrated within the storage device, the second data stream. The method further includes filtering, by the analyzer, the second data stream to generate debugging data; and sending, by the analyzer and to the host device, at least a portion of the debugging data.

Embedding analyzer functionality in storage devices

A method is disclosed that includes, generating, by a controller of a storage device, telemetry data associated with the storage device and stored in a memory device of the storage device. The method further includes determining, by the controller, a telemetry data loss warning condition indicating that a portion of the telemetry data is predicted to be overwritten in the memory device by more recent telemetry data. In response to determining the telemetry data loss warning condition, the controller transmits, to a host device, an asynchronous event notification indicating the telemetry data loss warning condition.
