1. A method, comprising: increasing spare space in a storage subsystem comprising a flash memory; extending a lifetime of the storage subsystem to achieve a stored selected minimum lifetime, at least in part as a result of the increasing spare space and enabling the spare space to comprise an increased amount of the flash memory; and delaying at least one operation that reduces the lifetime of the storage subsystem based on identifying an aspect associated with the lifetime of the storage subsystem, wherein the increasing the spare space comprises the storage subsystem compressing data stored in the flash memory, and wherein the increasing the spare space further comprises detecting deleted data and increasing spare space with space occupied with the deleted data.
