A disk drive includes a disk clamp for clamping a plurality of disks to a spindle motor, and a disk spacer positioned between first and second disks. The first disk has a plurality of first disk through apertures adjacent its inner diameter. The first disk through apertures are circumferentially spaced-apart and extend longitudinally through the first disk. The disk spacer has a plurality of spacer apertures that are circumferentially spaced-apart and extend longitudinally through a portion of a thickness of the disk spacer. The disk clamp is adjacent to the first disk and has a plurality of clamp through apertures adjacent an outer diameter of the disk clamp. The clamp through apertures are circumferentially spaced-apart and extend longitudinally through the disk clamp. The first disk through apertures, the spacer apertures, and the clamp through apertures are aligned for allowing airflow to pass through when the plurality of disks is rotating.
