A disk pack, comprising at least one hard disk, is rotatably mounted to a housing. The disk pack defines an axis of rotation and a radial direction relative to the axis. At least one actuator mounted to the housing is coupled with a suspension and is movable relative to the disk pack. A slider, comprising a slider body and a head configured to read data from and write data to at least one hard disk, is coupled with the suspension. A first suspension electrical interconnect is configured to electrically couple a first signal conducting pathway with the slider and with a first non-terminated signal pathway. A second suspension electrical interconnect is configured to electrically couple a second signal conducting pathway with the slider and with a second non-terminated signal pathway. The length of the second non-terminated signal pathway is selected to achieve a desired impedance level.
