Apparatuses, systems, methods, and computer program products are disclosed for model based configuration parameter management. An association module is configured to group a plurality of erase blocks of a non-volatile memory medium based on an amount of time since data has been written to the plurality of erase blocks. A read module is configured to sample data of at least two word lines from at least one erase block from each of a plurality of groups of erase blocks. A configuration parameter module is configured to determine different read voltage thresholds for different word lines of groups of erase blocks using different read voltage threshold models for different groups based on sampled data.
