PCIe TO 4-Ch SATA 3.0 Expander, 6Gpbs High-speed SATA Interface, Supports CM4.

Onboard SATA host controller (AHCI) with upstream PCle Gen3 x1 and downstream four SATA Gen3 ports. It's a low latency, low cost and low power AHCI controller. With four SATA ports and cascaded port multipliers, it can enable users to build up various high-speed IO systems, including server, high-capacity system storage or surveillance platforms
