HOOCCC Oculink SFF-8612 to M.2 NVMe SSD Adapter Board, PCIe 4.0 M-Key Converter
- Item #: 9SIVUB0M4V0924
- Mfr. Part #: M4B
- High-Speed PCIe 4.0 x4 Gen4 Transfer Supports up to 64Gbps bandwidth with backward compatibility for PCIe 3.0 x4 Gen3; performance tests show near-identical read/write speeds (~6428 MB/s read, ~2683 MB/s write) compared to direct SSD connection, ensuring minimal signal loss.
- Wide M.2 NVMe Compatibility Designed exclusively for M.2 NVMe protocol solid-state drives (not SATA); supports multiple SSD lengths including 2230, 2242, 2260, 2280, and 22110 via breakaway dotted lines to match your installation needs.
- OCuLink / SFF-8612 Input Interface Converts an OCuLink SFF-8612 port to a standard M.2 M-Key slot, ideal for storage expansion on mini PCs, desktops, laptops, and small-form-factor builds that feature an OCuLink output.
- Premium 4-Layer PCB Construction Built with a precision 4-layer bridging circuit, high-precision soldering, and electroplated gold-immersion contacts for military-grade reliability and stable, lossless high-frequency signal transmission; no external power supply required.
- Important Usage Note Hot plugging is NOT supported; always power off and disconnect your devices before plugging or unplugging to prevent hardware damage or data corruption. For best results, pair with a thickened / high-quality SFF-8611 OCuLink data cable (sold separately).

OCuLink SFF-8612 to M.2 M-Key NVMe Adapter Card PCIe 4.0 x4 Gen4 Storage Expansion
Unlock high-speed storage potential for your Mini PC, desktop, or laptop with this OCuLink SFF-8612 to M.2 M-Key NVMe adapter card. Designed to bridge an OCuLink output port to a standard M.2 NVMe SSD slot, this card enables external or internal PCIe 4.0 x4 Gen4 connectivity with bandwidth up to 64Gbps, making it an ideal solution for eGPU docks, NAS setups, and compact workstations requiring additional fast storage.
Exceptional Signal Integrity
Built on a premium 4-layer PCB with precision impedance control, this adapter ensures stable, low-latency data transmission. Electroplated gold-immersion contacts and high-precision SMT soldering minimize signal loss and crosstalk, delivering read/write performance nearly identical to direct motherboard connections (tested at approximately 6428 MB/s read and 2683 MB/s write). No external power supply is required, simplifying installation and cable management.
Broad SSD Compatibility
The M.2 slot supports a wide range of NVMe SSD form factors. Pre-scored breakaway sections allow you to customize the card length to fit 2230, 2242, 2260, 2280, and 22110 drives. Please note: this adapter is designed exclusively for NVMe protocol SSDs and is not compatible with M.2 SATA SSDs.
Reliable OCuLink Interface
Featuring a standard SFF-8612 input connector, this card pairs perfectly with OCuLink SFF-8611 cables (sold separately). The robust connector design ensures a secure fit and reliable data transfer, suitable for both stationary desktops and portable Mini PC applications.
Installation & Safety Notice
This adapter does not support hot-swapping. To protect your SSD, motherboard, and data integrity, always ensure all connected devices are completely powered off and unplugged before installing or removing the card or cable. We recommend using a high-quality, shielded OCuLink cable (preferably 0.5m or shorter for PCIe 4.0 applications) to achieve optimal performance.
