1. A method comprising: determining soft read information for a cell of a non-volatile storage medium; determining one or more reliability characteristics for the cell; and translating the soft read information to a log-likelihood ratio (LLR) value using an LLR mapping selected based on the one or more reliability characteristics, the LLR value indicating a probability that a data value for the cell is correct, wherein determining soft read information, determining one or more reliability characteristics, and translating the soft read information to an LLR value are performed by one or more of logic hardware and one or more processors executing computer usable program code.
