Abstract: Techniques arrange a disk, a storage device, and a disk array. Such techniques involve: a bracket configured to be detachably coupled to a rack; and a button arranged in the bracket and configured to be movable under the action of an external force to decouple the bracket from the rack, wherein a first end of the button is configured to be operated by a user, and the end surface of the first end includes a first surface and a second surface, the second surface extending from the first surface towards a second end, opposite to the first end, of the button. Accordingly, such techniques not only can avoid accidental touch, improve heat dissipation efficiency, and provide a mark area, but also can help prevent loss of user data in a storage device and a disk array.
