An MCIO x8 (SFF-TA-1016) 74-pin to 8x 7-pin SATA breakout cable connects one MCIO x8 host port to up to eight SATA drives. It is typically used with storage controllers, backplanes, or server motherboards that expose SATA lanes through an MCIO connector.

It is commonly used in servers, workstations, and storage systems to fan out a single high-density MCIO x8 connector into eight standard SATA data connections. This helps connect multiple HDDs or SSDs from a compact controller or motherboard port.

No. This cable usually carries SATA data signals only. Standard 7-pin SATA connectors do not provide power, so each drive still needs separate SATA power from the power supply or backplane.

Check that your motherboard, RAID card, HBA, or backplane has an MCIO x8 74-pin port that supports SATA breakout. Also confirm the port is not configured only for PCIe or NVMe, because physical compatibility does not always guarantee protocol compatibility.

A forward breakout cable typically goes from a controller or motherboard MCIO host port to multiple SATA drives. A reverse breakout cable is wired differently and is used for other signal-routing scenarios. Using the wrong type will not work, so verify the cable direction before purchase.
