Abstract
A storage system and method for thin provisioning are provided. In one embodiment, a storage system is provided comprising a memory and a controller. The controller is configured to provide a logical exported capacity of the memory to a host, wherein the logical exported capacity is greater than an actual storage capacity of the memory; receive a command from the host to write data to a logical address; determine whether there is available actual storage capacity in the memory to write the data; and write the data to a physical address in memory that corresponds to the logical address only if it is determined that there is available actual storage capacity in the memory to write the data. Other embodiments are possible, and each of the embodiments can be used alone or together in combination.
