A removeable drive-plane board may include (1) keyhole openings that are configured to interlock with keyhole fasteners of a retaining member of a storage-system chassis, (2) storage-drive connectors, (3) a storage-system module connector, and (4) electrical interconnects that electrically couple the storage-drive connectors to the storage-system module connector. In some examples, the keyhole fasteners of the retaining member may be oriented downward relative to the storage-system chassis. Various other removeable drive-plane apparatus, systems, and methods are also disclosed.
