Dual SFF-8654 8X 74Pin Adapter
This SMUGDESK adapter converts a PCIe 16X slot into two SFF-8654 8X 74Pin SlimSAS ports for external U.2 NVMe SSD connections. It supports PCIe 4.0 and remains backward compatible with PCIe 3.0 for high-speed storage transmission. The built-in VROC and RAID0 functions enable hardware or software RAID arrays to boost sequential read and write performance. A detachable bifurcation design allows the x16 lane to split into two x8 channels based on motherboard BIOS support.
Enterprise storage builders and workstation users
The card suits builders assembling high-capacity NVMe arrays on Intel or AMD platforms using mainstream motherboards from major vendors. It is not for users lacking a free PCIe 16X slot or whose motherboard BIOS does not support bifurcation into x8/x8 lanes. Buyers needing internal drive connections or single-port expansion should look at different adapter types. Systems without VROC support or RAID requirements will not use the card’s key hardware features.
Detachable bifurcation and VROC RAID0
The detachable PCIe bifurcation structure physically separates the x16 interface into two independent x8 channels, allowing flexible lane allocation per hardware requirement. Integrated Intel VROC support provides hardware RAID0 without consuming CPU cycles, while standard software RAID0 remains an option. These features combine to enable high-performance NVMe disk arrays for data processing and industrial storage projects. No additional software licences or cables are mentioned in the supplied data.

Questions about this item
What motherboard slot does this adapter need to plug into?
The adapter plugs into a PCIe x16 slot and requires the motherboard to support bifurcation so the x16 link can split into two x8 channels.
Will my PCIe 3.0 motherboard still let the adapter run the external U.2 NVMe drives?
Yes, the card is PCIe 4.0 and backward compatible with PCIe 3.0, so the drives will operate at PCIe 3.0 speeds on a 3.0 platform.
How can I confirm the VROC RAID0 array is active after installation?
Enter the BIOS or UEFI, enable VROC, create the RAID0 volume across the two SFF-8654 ports, then verify the array appears as a single NVMe device in the OS disk manager.
