PCIe Gen5 MCIO to MCIO 8X 74Pin Cable - High-Speed Server Link

In this review the MCIO to MCIO 8X 74Pin Cable is evaluated as a focused solution for rack servers, NVMe backplanes and HBAs where compact, high-bandwidth links are required. The cable's single biggest selling point is support for PCIe Gen5 data rates with silver-plated AWG30 twinax conductors, which makes it a clear choice for administrators upgrading storage fabrics or all-flash arrays who need reliable, shielded connectivity over a short distance.

Key Features

• PCIe Gen5 support: Enables up to 32 Gbps per lane for higher throughput and future-proofing storage and HBA connections.
• MCIO connectors: Both ends use SFF-TA-1016 compatible MCIO terminations to mate cleanly with Mini Cool Edge IO interfaces on backplanes and expansion cards.
• Silver-plated AWG30 twinax: Provides improved signal integrity and lower loss across the short cable run common in server bays.
• 85 Ohm impedance and full shielding: Reduces crosstalk and EMI, making the cable suitable for dense server and data center environments.
• Compact length: At roughly 0.75 to 0.8m (2.46 to 2.62 ft) the cable fits typical rack layouts without excess slack while preserving performance.

Who It's For

This cable is intended for system integrators, data center technicians and storage administrators replacing or adding short-reach connections between NVMe backplanes, HBAs and all-flash arrays that use the MCIO interface. It is especially useful when upgrading systems to take advantage of PCIe Gen5 lane speeds while keeping a fully shielded, impedance-controlled link.

It is not aimed at casual desktop users or anyone whose hardware lacks MCIO/SFF-TA-1016 ports or PCIe Gen5 support; check compatibility on the motherboard, expansion cards and storage devices before purchasing. Longer-reach or field-repair scenarios may require different cable types.

Pros & Cons

Pros

• High bandwidth thanks to PCIe Gen5 capability and 32 Gbps per lane support.
• Robust signal integrity from silver-plated AWG30 twinax conductors and full shielding.
• Designed to SFF-TA-1016 MCIO connector standards for reliable mating in server hardware.

Cons

• Short fixed length (0.75~0.8m) limits flexibility if longer cable runs are needed.
• Requires compatible MCIO ports and Gen5-capable devices, so verification is essential before purchase.

Our Verdict

For professionals building or upgrading dense storage systems, this MCIO to MCIO cable delivers the necessary PCIe Gen5 bandwidth and shielding in a short, rack-friendly package. It offers good value when compatibility is confirmed and the installation requires a high-integrity short-reach connection to NVMe backplanes or HBAs.

Frequently Asked Questions

Will this cable work with PCIe Gen4 devices?
The cable will operate with Gen4 devices, but you will only achieve Gen4 lane speeds unless both endpoints support Gen5.

How long is the cable and is a longer version available?
The supplied length is about 0.75~0.8 m (2.46~2.62 ft); longer lengths are not included in this product description and may require a different part.

Do I need to verify compatibility before buying?
Yes, confirm that your motherboard, expansion card or storage backplane uses MCIO/SFF-TA-1016 connectors and supports PCIe Gen5 if you need Gen5 speeds.
