LRNV9F14 PCIe x16 to Two SlimSAS SFF-8654 8i Adapter - NVMe Bifurcate

Our review of the LRNV9F14 PCI Express x16 to Two SlimSAS SFF-8654 8i Adapter finds it a focused tool for system builders who need to connect multiple NVMe drives using a single PCIe x16 slot. The bottom line: this adapter is for technicians and enthusiasts who have motherboards and BIOS that support PCIe bifurcation and want a compact way to route up to four NVMe SSDs or two x8 links over SlimSAS SFF-8654, offering a practical conversion without drivers or added software complexity.

Key Features

• PCIe 4.0 compatibility: Designed for PCIe 4.0 U.2 SSDs so it can take advantage of higher bandwidth when the motherboard slot supports it.
• SFF-8654 SlimSAS connectors: Provides two SlimSAS SFF-8654 8i ports to connect NVMe or PCIe devices using industry standard cabling.
• Bifurcation support: Allows use of motherboard bifurcation to split an x16 slot into two x8 or four x4 links for multiple NVMe drives when the platform supports it.
• No driver required: Operates without additional drivers, so attached NVMe SSDs are managed by the system OS and NVMe stack natively.
• Backward compatible: Compliant with PCIe 1.0 through 4.0, enabling use on older systems at reduced link speeds.

Who It's For

The LRNV9F14 is aimed at IT professionals, server builders, and advanced PC enthusiasts who need to connect multiple NVMe drives through a single PCIe x16 slot and have motherboards that support PCIe bifurcation. It is also useful for small form factor systems using SlimSAS cabling where internal drive bays or backplanes require SFF-8654 connections.

Users without a motherboard that supports bifurcation, casual PC builders, or those expecting an external USB-like adapter should look elsewhere, because without BIOS support this card can only operate as a straight x16 link and will not split lanes for multiple NVMe devices.

Pros & Cons

Pros

• Enables multi-NVMe configurations through two SFF-8654 ports for consolidated cabling and simplified routing.
• Supports PCIe 4.0 and is backward compatible, so it fits a broad range of systems while allowing higher throughput where available.
• Driverless operation reduces setup complexity and relies on native NVMe support in the OS.

Cons

• Requires motherboard and BIOS bifurcation support to split the x16 slot into multiple links for full multi-drive use.

Our Verdict

The LRNV9F14 is a practical and economical adapter for builders who need to route multiple NVMe drives through a PCIe x16 slot and have a platform that supports bifurcation. It delivers compatibility with PCIe 4.0 and standards-based SlimSAS connectors without driver fuss, making it good value for server and workstation builds that require compact NVMe connectivity.

Frequently Asked Questions

Do I need a special driver?
No, the adapter does not require a driver and relies on the operating system and NVMe stack to communicate with attached SSDs.

Will it split an x16 slot automatically?
The card can only make use of bifurcation if the motherboard, CPU, and BIOS support splitting the x16 link into two x8 or four x4 links; otherwise it functions as a single x16 link.

How many NVMe drives can be attached?
The design supports up to four NVMe SSDs when used with appropriate bifurcation and cabling to compatible backplanes or drive carriers.
