A method for determining a utilization-based fee for storing data includes determining a number of write operations for writing a quantity of data to a solid state drive (SSD) and determining an amount of a fee based on the number of write operations for writing the quantity of data to the SSD. A lifetime of the SSD can be determined based on, for example, the number of blocks in the SSD and the maximum number of write operations per block. A utilization factor for a particular workload can be determined by dividing the number of write operations in the workload by the lifetime. The value of the utilization factor can then be used to determine the amount of the fee. A bill based on the amount of the fee can be generated and transmitted.

Data storage device, method and system, and control of data storage device based on writing operations and lifetime

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.
