1. A method to determine a direction to adjust a read voltage threshold for solid-state storage media, the method comprising:

  • reading a data set from storage cells of solid-state storage media, the data set originally stored in the storage cells with a known bias;

    determining that a read bias for the data set deviates from the known bias; and

    determining a direction of deviation for the data set based on a difference between the read bias and the known bias.
