Abstract
A data storage device includes a number of blocks in multiple dies and a controller configured to perform operations. A method of controlling the data storage device includes: translating logical addresses to physical addresses; activating one or more dies; writing data to one or more blocks; determining the number of write operations performed on the storage device; facilitating determination of a lifetime of the storage device based on a number of blocks, a particular number of write operations, and a maximum number of write operations per block; providing the number of write operations that have been performed to a host to facilitate determination of an amount of a fee, where providing the number of write operations facilitates tracking a percentage of the lifetime of the storage device.
