Low-profile green circuit board with two SFF-8654 74Pin ports and a detachable PCIe x16 edge connector

SMUGDESK

SMUGDESK Low Profile Dual SFF-8654 74Pin to PCIe 3.0/4.0 x16 VROC RAID0 Hyper Adapter

SKU CH-P9ZY-Q4MKX

Converts one PCIe 3.0/4.0 x16 slot into two SFF-8654 74Pin ports for up to 4 NVMe drives at 128Gbps total bandwidth

  • Low-profile slimline design fits compact SFF cases
  • Dual SFF-8654 74Pin ports deliver up to 128Gbps total bandwidth
  • PCIe 3.0/4.0 compatible with x16, x8, and x4 slots
  • Intel VROC certified for NVMe RAID0 with x8/x8 bifurcation
  • Supports up to 4 NVMe SSDs for high-capacity storage expansion

Low Profile Dual SFF-8654 Adapter

This low profile adapter fits slim SFF cases and converts a PCIe 3.0/4.0 x16 slot into two SFF-8654 74Pin ports. It supports up to 4 NVMe SSDs through Intel VROC RAID0 with motherboard x8/x8 bifurcation. The detachable PCIe x16 connector allows flexible mounting in compact chassis. It is not for builders without bifurcation support or those needing a single drive connection.

Sustained 128Gbps Bandwidth

Each SFF-8654 port delivers up to 64Gbps for a combined 128Gbps across two ports. The design maintains stable 24/7 enterprise operation under continuous NVMe workloads. PCIe 4.0 16GT/s and 3.0 8GT/s compatibility ensures full lane utilisation during extended transfers. It is not for platforms limited to PCIe 3.0 x8 electrical width.

Detachable Connector Install

The detachable PCIe x16 connector simplifies routing in tight small form factor builds. Installation requires motherboard BIOS support for x8/x8 bifurcation to enable RAID0 across four drives. Incorrect bifurcation settings are the most common cause of undetected drives. It is not for systems lacking low profile bracket clearance or VROC licensing.

Questions about this item

How much heat does the dual SFF-8654 adapter add when running four NVMe SSDs continuously?

The low-profile card has no active cooling; it relies on case airflow to dissipate heat from the PCIe 3.0/4.0 switch and the four NVMe drives, so sustained loads need good chassis ventilation.

What motherboard feature must I already have to use the VROC RAID0 function on this adapter?

The board must support PCIe x8/x8 bifurcation on the x16 slot; without that split the Intel VROC RAID0 mode cannot initialise across the two SFF-8654 ports.

Will this adapter work in an older PCIe 3.0 x16 slot without losing the ability to run four NVMe drives?

Yes — the card is PCIe 3.0/4.0 compatible, so in a Gen3 x16 slot it still provides two x8 SFF-8654 links, giving each NVMe SSD a Gen3 x4 connection for full four-drive operation.
