Hard drives are the primary bottlenecks in today's high-speed computers, and this is partially due to the limitations of PATA. Since Serial ATA is a completely new and faster standard, there will be an industry wide move over to new hard drives,controllers, and connectors-essentially everything will move to Serial ATA.

150 Mbyte/s maximum transfer rate ( 300 / 600 MByte/s envisioned for the future ) between two SATA I (150Mb) devices, capable up to 4.5 Gbyte/s Hot-plug capability ; Two power saving modes : partial and slumber Overlapping (commands) ; Tagged command queueing Smaller, longer and more flexible cable and Smaller connector.
