Abstract
In general, embodiments of the technology relate to a method for adjusting solid state memory write parameters. The method includes obtaining a performance goal for the solid state memory, receiving a client write request for data from a client, where the client write request comprises a logical address and data to be written. The method further includes determining a physical address corresponding to the logical address, where the physical address comprises a page number for a physical page in the persistent storage, obtaining at least one verify threshold value using the performance goal, issuing a control module program request including the data to be written and the at least one verify threshold value to a storage module, where the storage module comprises the physical page, and programming the data into the physical page of the storage module using the at least one verify threshold value.
