Black cable with wide MCIO connector splitting to two Mini SAS HD ends

SMUGDESK

SMUGDESK PCIe 5.0 MCIO 8X 8i to Dual Mini SAS HD SFF8643 Cable 1m

SKU CH-PENS-K7DNQ

PCIe 5.0 breakout cable converts one MCIO 8X 8i port to dual SFF8643 Mini SAS HD connectors for NVMe, SAS and SATA drives at 32Gbps over a 1m low-loss copper harness

  • Converts MCIO 8X 8i to dual SFF8643 ports for flexible storage expansion
  • Delivers 32Gbps bandwidth for NVMe SSDs and SAS drives
  • Premium low-loss copper harness minimizes signal attenuation
  • 1-meter length enables routing in rackmount servers and workstations
  • Optimized shielding reduces crosstalk for reliable data center deployment

PCIe 5.0 MCIO breakout cable

The SMUGDESK cable converts a single MCIO 8X 8i port into two independent SFF8643 Mini SAS HD connections. It is designed for administrators and integrators expanding NVMe or SAS storage inside rackmount servers and dense workstations. The 1m harness fits standard chassis routing paths without excess slack.

Sustained 32Gbps throughput

Premium low-loss copper and optimized shielding keep signal attenuation minimal during continuous heavy I/O. The construction resists crosstalk so bandwidth remains stable across both lanes when driving enterprise RAID controllers or large-capacity NVMe arrays. Performance stays consistent under prolonged workloads rather than only in short bursts.

Replaces older Gen4 or single-port links

Upgrading from a PCIe 4.0 or single-lane cable removes the bottleneck that limits modern NVMe SSDs and high-speed SAS drives. The jump is worthwhile when the backplane, controller and drives all support 32Gbps operation and the chassis can accommodate the 1m reach. Builders needing longer runs or different connector types should look elsewhere.

Questions about this item

Does the 1 m cable length and copper harness generate noticeable heat or power draw during all-day 32 Gbps transfers?

The passive copper harness draws no extra power and produces negligible heat even at continuous 32 Gbps throughput.

What host connector must my motherboard or controller already provide for this MCIO 8X 8i plug to seat correctly?

A single PCIe 5.0 MCIO 8X 8i receptacle is required on the host side.

Will the dual SFF-8643 ends work with my existing SAS or SATA backplanes and NVMe U.2 drives without adapters?

Yes, each SFF-8643 port connects directly to standard SAS, SATA or NVMe U.2 backplanes using native SFF-8643 cables.
