SMUGDESK SFF8654 8i to 8-port SATA cable .8m 32AWG 85Ohm

SMUGDESK

SMUGDESK MCIO SFF8654 8i to 8Port SATA .8m 32AWG 85Ohm

SKU CH-MC78-HC5J9

Breaks one SFF-8654 8i MCIO port into eight SATA 7-pin ports using 32AWG copper and 85 Ohm impedance for reliable high-speed server storage expansion

  • Straight connectors simplify internal routing in standard server chassis
  • Single SFF8654 8i MCIO port breaks out to eight SATA 7pin female ports for multi-drive expansion
  • Controlled 85Ohm impedance maintains stable signal integrity with low transmission loss
  • 32AWG copper conductors deliver high-bandwidth data transfer for enterprise storage systems
  • .8 meter length optimised for clean medium-short range wiring in high-density server builds

MCIO SFF-8654 8i breakout cable

The SMUGDESK cable adapts a single MCIO SFF-8654 8i port to eight independent SATA 7-pin female connectors. It is built for server administrators expanding internal storage arrays in standard chassis layouts. The straight connector profile keeps routing tidy inside dense enclosures.

Eight SATA ports with 85 Ohm controlled impedance

The 32 AWG copper conductors and strict 85 Ohm impedance preserve signal integrity across the .8 metre run. This configuration comfortably handles multi-drive HDD and SSD sets attached to a backplane or RAID controller. Bandwidth per drive drops when all eight ports are saturated simultaneously.

SAS and SATA interface practical limits

The cable passes SAS and SATA protocols through the MCIO physical layer without protocol conversion. Maximum throughput is bounded by the host controller's lane allocation and the SATA revision supported by the attached drives. Cable length fixes the reach at .8 metres, limiting placement to adjacent backplanes or drive cages.

Questions about this item

Will the SFF8654 8i connector on this cable fit the MCIO slot on my existing server board?

The cable terminates in a single SFF8654 8i MCIO plug designed for straight insertion into a matching MCIO PCIe SAS port on the host board.

How can I verify the 85Ohm controlled impedance is performing correctly after installation?

Confirm each of the eight SATA drives is detected at full link speed in the BIOS or RAID controller utility and run a sustained read/write test to check for errors.

Does the 0.8m cable include the eight SATA drives or only the breakout cable itself?

Only the breakout cable is supplied — one SFF8654 8i end to eight SATA 7‑pin female connectors; drives and any mounting hardware must be purchased separately.
