AV disks support ATA streaming command set, are designed to last
in high temperature always-on streaming digital AV environments, are
silent, with Preemptive Wear Leveling (PWL) (the drive arm frequently
sweeps across the disk to reduce uneven wear on the drive surface
common to audio video streaming applications)

(paraphrased from WD docs)
