Fervit Oculink SFF-8612 SFF-8611 to M.2 NVME PCIe 4.0 Adapter

SKU CH-KKE6-8A24K

Connects M.2 NVME SSDs in 2230, 2242, 2260 and 2280 sizes to a motherboard via SFF-8611 or SFF-8612 OCuLink using PCIe 4.0 x4

  • Supports M.2 NVMe SSDs in 2230, 2242, 2260 and 2280 form factors
  • Connects internally via SFF-8611 or SFF-8612 OCuLink 4x interface
  • Operates at PCIe 4.0 x4 speeds for high-throughput storage
  • Designed exclusively for NVMe drives, not compatible with SAS or SATA protocols
  • Enclosure-style adapter mounts directly to mainboard for internal installation

Fervit Oculink to M.2 NVMe Adapter

This Fervit adapter connects a single M.2 NVMe PCIe SSD to an Oculink SFF-8611 or SFF-8612 interface. It accepts 2230, 2242, 2260 and 2280 form factors for internal installation. The unit is designed for PCIe 4.0 x4 operation with a Hyper Kit Storage controller. It does not support SAS or SATA protocols.

PCIe 4.0 x4 Oculink Interface

The decisive specification is the PCIe 4.0 x4 electrical interface carried over the Oculink connectors. This determines whether the host system can deliver full bandwidth to the installed NVMe drive. The adapter will not function with SAS, Slimline SAS or SATA host connections. Protocol mismatch is the primary compatibility risk.

Internal Installation and Protocol Limits

Installation requires an available internal Oculink port on the mainboard or add-in card and physical clearance for the M.2 module. No driver is needed for the adapter itself. Common issues arise when users attempt to connect SATA-based M.2 drives or SAS equipment, which the converter explicitly cannot support.

Questions about this item

What PCIe 4.0 x4 bandwidth does the Oculink SFF-8612 SFF-8611 link actually deliver to an M.2 NVME SSD?

The adapter passes a full PCIe 4.0 x4 connection through the Oculink 4x interface, so an M.2 NVME SSD sees the same four-lane bandwidth it would on a native motherboard slot.

Does the SFF-8612 SFF-8611 Oculink interface limit the drive to a lower PCIe generation or lane count?

No, the Oculink 4x connectors carry PCIe 4.0 x4 signals without down-negotiation, so the drive runs at its rated generation and lane width.

Which M.2 NVME SSD lengths fit the adapter and how are they secured?

The board accepts 2230, 2242, 2260 and 2280 M-key NVME drives; each length uses the standard M.2 mounting hole for a retention screw.
