An example carrier module may include a carrier board. The carrier board may include a storage drive interface and an adapter connector in electrical communication with the storage drive interface. The adapter connector may engage with a complementary adapter receiver. The adapter connector may include a plurality of signal pins, at least one ground pin that is longer than the signal pins, and at least one power pin that is longer than the signal pins. The plurality of signal pins, the at least one ground pin, and the at least one power pin may engage with the adapter receiver to facilitate electrical communication between the adapter receiver and the adapter connector.
