Abstract
In general, embodiments of the technology relate to a method for characterizing persistent storage. The method includes selecting a sample set of physical addresses in a solid state memory module, where the sample set of physical addresses is associated with a region in the solid state memory module (SSMM). The method further includes issuing a write request to the sample set of physical addresses, after issuing the write request, issuing a request read to the sample set of physical addresses to obtain a copy of the data stored in the sample set of physical addresses, obtaining an error parameter for the copy of the data, determining a calculated P/E cycle value for the SSMM using at least the error parameter; and storing the calculated P/E cycle value in the SSMM.
