摘要：
A storage device controller coupled to a storage device having a multiple locations for storing data coupled to may receive a WRITE ANYWHERE command including write data but not specifying a location of the storage device where the write data should be stored. The controller responds to the WRITE ANYWHERE command by selecting one or more unused locations of the storage device, and writing the write data in the one or more unused locations of the storage device. After writing the write data to the storage device, the controller may report where the write data is stored to the host. The host may also issue FREE commands to the controller specifying locations of the storage device which should be identified as unused. In response to a received FREE command, the controller may store information in a memory indicating that the location specified by the FREE command is unused.
