ABSTRACT:
Methods and systems for improving communication throughput of a link between SAS/SATA devices. The link, initially established at a first signal rate, is one of a SATA link and a SAS link. A SAS/SATA device increments one of the at least one counter based on an error sensed on the link. Based on the at least one counter, the SAS/SATA device determines whether to maintain the first signal rate. The link is re-established at a second signal rate based on the determination such that the second signal rate is lower than the first signal rate.
