Vszerda Quad U.2 NVME PCIe 4.0/3.0 x16 Expansion Card

Quad U.2 NVMe expansion card

This Vszerda add-in card connects four U.2 NVMe solid-state drives to a single PCIe 4.0 or 3.0 x16 slot. It is built for workstations and servers that need high-density local storage without occupying multiple expansion slots. The board uses SFF-8643 MiniSAS connectors that link to SFF-8639 U.2 drives via separate cables.

Sustained throughput with bifurcation

When the motherboard supports PCIe x16 bifurcation the card delivers up to 32 Gbps of aggregate bandwidth across all four drives simultaneously. Without bifurcation the system will only recognise a single drive, so the full four-drive performance depends entirely on the platform capability. The on-board LED shows activity status for each connected device during heavy workloads.

Verify bifurcation and cable needs

Confirm that your motherboard firmware explicitly supports PCIe x16 bifurcation before purchase; otherwise only one drive will be detected. The card fits only a full-size PCIe x16 slot and will not work in x1, x2, x4 or x8 slots. SFF-8643 to SFF-8639 cables are not included and must be sourced separately for each drive.
