A disk drive includes a drive housing, one or more rotating storage disks, each having a storage surface, and a fluid diffuser. The fluid diffuser includes one or more stationary diffuser wings, each having a wing surface positioned near the storage surface. One or more of the diffuser wings can extend between two of the storage disks. The diffuser wing includes a surface deviation that disrupts the fluid flow over the wing surface that is caused by the rotating storage disk. The surface deviation can include an indentation in the wing surface or can extend from the wing surface toward the storage surface. In still another embodiment, the surface deviation includes an aperture that extends through the diffuser wing. Further, the fluid diffuser can include a plurality of surface deviations that are positioned along the wing surface. Further, a portion of the surface deviation can form an angle with the wing surface that is greater than approximately 0 degrees and less than approximately 180 degrees. With this design, the fluid diffuser decreases fluid velocity near the data transducers and/or the rotating storage disks.
