Cable for data storage accessories icy dock MB413L-B — MCIO x8 to 2× MCIO x4, black, 500 mm, UL20744

The icy dock MB413L-B is a 500 mm black internal data cable that converts one MCIO x8 (SFF‑TA‑1016) interface into two MCIO x4 (SFF‑TA‑1016) interfaces. Designed for use in servers, RAID enclosures and drive backplanes, this single-piece cable supports high-speed NVMe and tri-mode host bus adapter/RAID connections while meeting UL20744 safety certification.

Advantages

The MB413L-B follows SFF‑TA‑1016 connector design specifications and supports transfer rates compatible with PCIe 5.0, enabling reliable connectivity for modern storage devices. Its single-piece construction and integrated pull tabs simplify installation and removal in high-density environments. UL20744 certification confirms compliance with recognized safety standards for internal data cables.

Suitable for

• Connecting a single MCIO x8 port to two MCIO x4 drive paths in servers and storage enclosures
• Expanding MCIO interfaces on NVMe/Tri-mode HBA or RAID controller cards
• Internal cabling between backplanes and host cards in rackmount systems

When it may not be suitable

This cable is intended for internal system use and is not designed for external or exposed installations where environmental protection is required. It is a fixed 500 mm length; systems that require a different cable length or field-terminated wiring will need an alternative solution.

Key specifications

• Connector types: MCIO x8 (input) to 2 × MCIO x4 (outputs), SFF‑TA‑1016 compliant
• Length: 500 mm
• Color: Black
• Support: Compatible with NVMe and tri-mode HBA/RAID cards
• Performance: Transfer rate compatible with PCIe 5.0 signaling
• Certification: UL20744
• Quantity: 1 piece per pack

How to use

Route the cable inside the chassis between the host card MCIO x8 port and the target backplane or device MCIO x4 ports. Align the SFF‑TA‑1016 connectors and press until the latch engages; use the pull tabs to release connectors during removal. Ensure cable length and bend radius are respected to avoid signal degradation and that connectors are fully seated before powering the system.

What to consider before purchase

• Verify that host card and backplane connectors follow SFF‑TA‑1016 (MCIO) specifications
• Confirm 500 mm length meets routing requirements inside your chassis
• Check compatibility with your NVMe or tri-mode controller and enclosure design
• Consider whether UL20744 certification and internal-only use meet your installation policies

Usage recommendations

For optimal performance, avoid tight bends and excessive compression of the cable, ensure secure seating of connectors, and perform a system-level validation after installation to confirm link negotiation and drive visibility.
