1. A method of determining an equalized signal-to-noise ratio in a storage device, the method comprising steps of:

  • (a) generating an analog read signal;

    (b) passing the analog signal through an equalizer in the storage device to produce an equalized signal;

    (c) sampling the equalized signal using an analog to digital converter in the storage device to produce equalized samples; and

    (d) calculating the equalized signal-to-noise ratio based on the equalized samples.
