Abstract
Monitors, architectures, systems and methods for determining one or more quality characteristics of a storage channel. The monitor generally includes an iterative decoder configured to decode data from the storage channel and generate information relating to a quality metric of the storage channel and/or the iterative decoder, a memory configured to store a threshold value for the quality metric, and a comparator configured to compare the threshold value with a measured value of the quality metric. The monitor enables accurate determination of storage channel quality without use of conventional Reed-Solomon metrics.
