Four-Port U.2 NVMe Expansion Card
The LRNV9347-4I is a PCIe 3.0 x16 add-on card that connects four U.2 NVMe solid-state drives through SFF-8643 connectors. A PLX 8747 switch provides a dedicated PCIe 3.0 x4 lane to each drive so all four operate at full speed simultaneously. The card fits a standard x16 slot and ships with both a full-height and a low-profile bracket. It is built for servers and workstations that need dense, high-throughput NVMe storage.
Suited for multi-drive NVMe arrays.
This card targets administrators building high-capacity NVMe arrays for databases, virtualisation or content-ingestion workloads where four drives must run concurrently without bandwidth contention. It is not intended for users adding a single NVMe drive to a desktop, nor for systems that lack a physical x16 slot or that only support PCIe 2.0 or earlier. Buyers who need more than four U.2 ports or who require PCIe 4.0 signalling should look at alternative switch cards.
Aggregate 128 Gb/s host bandwidth
The PLX 8747 delivers up to 128 Gb/s of aggregate PCIe 3.0 bandwidth to the host while each of the four ports sustains up to 32 Gb/s to its attached NVMe SSD. This headroom handles simultaneous heavy read and write streams across all four drives, such as parallel database logs or multi-camera video ingest. Performance will be limited by the host platform’s PCIe 3.0 x16 ceiling; workloads demanding PCIe 4.0 or 5.0 throughput exceed what this card can provide.

Questions about this item
Does my motherboard need a PCIe 3.0 x16 slot to install this LRNV9347-4I card?
Yes, the card requires a PCIe 3.0 x16 host bus slot to deliver dedicated x4 bandwidth to each of the four U.2 NVMe drives.
Can I keep using my PCIe 2.0 or 1.1 expansion cards in other slots while this adapter runs at PCIe 3.0 speeds?
The adapter is compliant with PCIe 3.0, 2.0, 1.1 and 1.0a specifications, so it will coexist with older-generation cards on the same platform.
How can I verify that all four U.2 NVMe SSDs are operating at full 32 Gb/s transfer rate after setup?
Check the operating system device manager or BIOS to confirm each drive negotiates a PCIe 3.0 x4 link, which provides the stated 32 Gb/s per SSD.
