A dispersed storage (DS) unit a processing module and a plurality of hard drives. The processing module is operable to maintain states for at least some of the plurality of hard drives. The processing module is further operable to receive a memory access request regarding an encoded data slice and identify a hard drive of the plurality of hard drives based on the memory access request. The processing module is further operable to determine a state of the hard drive. When the hard drive is in a read state and the memory access request is a write request, the processing module is operable to queue the write request, change from the read state to a write state in accordance with a state transition process, and, when in the write state, perform the write request to store the encoded data slice in the hard drive.
