Embedding analyzer functionality in storage devices

A data storage device comprising:

• a mass storage device;
• a controller configured to manage read operations from the mass storage device and write operations to the mass storage device;
• an interface comprising at least one signal splitter;
• and
• an analyzer,
• wherein the signal splitter is configured to:
• receive, from a host device, an electrical signal representative of data;
• split, 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;
• send, to the controller, the first data stream;
• and
• send, to the analyzer, the second data stream;
• and
• wherein the analyzer is configured to:
• filter the second data stream to generate debugging data;
• and
• send, to the host device via the interface, at least a portion of the debugging data.
