1. A method for decoding data in non-volatile storage, comprising:

  • performing a first sense operation on at least one non-volatile storage element;

    providing a first code word based on the first sense operation;

    performing a decoding process for the first code word using a first set of reliability metrics which is based on the first code word; and

    if the decoding process does not meet a first condition, the first condition comprises the decoding process converging within a given time period, performing a second sense operation on the at least one non-volatile storage element and continuing the decoding process based on the second sense operation.
