Abstract

Techniques involve determining a first remaining lifetime of a flash device at a first time based on a warranty period, a factor of the number of writes per unit of time, and the number of executed writes for the flash device. The techniques further involve obtaining a second remaining lifetime at a second time prior to the first time, the second remaining lifetime being determined at the second time based on the warranty period, the factor of the number of writes per unit of time, and the number of executed writes. The techniques further involve determining a first lifetime decay rate based on the first and second remaining lifetimes. In addition, the techniques may determine a first predicted remaining lifetime based on the first lifetime decay rate. Accordingly, a remaining lifetime can be predicted based on the usage trend thereof.
