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.
