We are using SDK V1.8 with LS1021A. We are using the dd application to measure SATA and USB 3.0 throughput. We are measuring 95 MB/s on USB 3.0 but only ~45MB/s on SATA. We know that the SATA drives that we are testing with are capable of much higher throughput ( > 150 MB/s). Does anyone know the cause of this very slow throughput?
