The present invention provides a device and method for mitigating performance degradation caused by SATA drives attached to a SAS domain. In one of the embodiments of the present invention, a SATA degradation mitigation device (“SDMD”) is installed between a SAS domain and one or more SATA drives. The SDMD effectively reduces congestion on intermediate links by buffering SATA data and transmitting the data at a rate which is higher than the rate at which the SATA data is received from a drive. Conversely, write data from the SAS domain may be buffered at the SDMD at a higher rate and subsequently sent to the SATA drive at a lower rate. This SATA data buffering and subsequent increase in data rate improves the overall efficiency of a SAS domain storage system by reducing data congestion arising out of low-performance SATA drives clogging the intermediate links.
