Vszerda

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

SKU CH-KD0H-SBKAE

Adds four U.2 NVME drives via a PCIe 4.0/3.0 x16 slot with bifurcation support and 32Gbps bandwidth

  • Connect four U.2 drives through one PCIe x16 slot
  • 32Gbps bandwidth via PCIe 4.0 or 3.0 x16 interface
  • LED indicator shows drive activity at a glance
  • Includes full-height and low-profile brackets for any case
  • Requires motherboard PCIe x16 bifurcation for all four drives

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.

Questions about this item

Does the card add much heat or noise when four U.2 NVMe drives run all day?

The card is a passive adapter with no fan or active cooling; heat and noise depend entirely on the drives you install and your case airflow.

What motherboard feature must I already have for all four drives to appear?

Your motherboard must support PCIEX16 bifurcation; without it only one drive will be recognised.

Will this card work in an older PCIe 3.0 x16 slot while keeping the drives at full speed?

Yes, the card is compatible with PCIe 3.0 x16 slots, though the 32 Gbps maximum signal rate is only reached with PCIe 4.0.
