Claim:
An apparatus comprising: an enclosure; a substrate held within the enclosure and having a plurality of disk-drive connectors positioned in a first row extending generally from an air-inlet side of the enclosure to an air-outlet side of the enclosure including a first disk-drive connector and a second disk-drive connector that are adapted to be connected to a first disk drive and a second disk drive, respectively; wherein the first and second disk drives each have a first major face A and a second opposite major face B, wherein face B includes a circuit card; wherein the disk drives each have an actuator, and an axis of rotational mass intersecting and perpendicular to face A; wherein the first disk-drive connector and the second disk-drive connector are positioned at least as close to one another as to other disk-drive connectors; wherein when connected to their respective disk-drive connector, the first disk drive's major face A and second disk drive's major face B are positioned facing each other, substantially parallel and next to each other such that air flows from the air inlet side of the enclosure to a manifold along one side of the first row, then between the first and second drive to a manifold along an opposite side of the first row, and then to the air outlet side of the enclosure.
