1. A method for managing the location of data in a high density disk drive enclosure, comprising: receiving data to be stored to a disk drive in a high density drive enclosure having a plurality of disk drives positioned within a cooling airflow from an airflow source; determining the expected usage of the received data relative to other data stored on disk drives in the enclosure; and directing that the received data be stored in a disk drive having a position within the airflow relative to the source of the airflow in direct relationship to the relative expected usage of the received data, whereby data having a higher expected usage is stored in a disk drive closer to the airflow source relative to other data having a lower expected usage and data having a lower expected usage is stored in a disk drive farther from the airflow source relative to other data having a higher expected usage.
