Red PCIe expansion card with four M.2 NVMe slots

Hetai Tech

Hetai Tech 3.0 X4 PLX8724 4 Port M.2 NVMe Adapter Red

SKU CH-N7S7-JWGQZ

Expands one PCIe x16 slot into four NVMe ports running at full speed on motherboards that support lane bifurcation

  • Adapter typeUSB to DB9 (RS-232)
  • Supports four NVMe drives at full speed simultaneously
  • Requires motherboard with PCIe lane splitting capability
  • Maximum combined throughput exceeds 10000 MB/s
  • Compatible with Windows, Mac OS and Linux
  • Built-in high-power DC modules for stable operation

4-Port NVMe Adapter for PCIe Channel-Splitting

This red expansion card uses a PLX8724 bridge to present four M-key NVMe slots over a single x16 link. It is aimed at users whose motherboard firmware and CPU lane allocation can bifurcate that link into four x4 electrical paths, letting each drive run at its rated throughput.

Red PCB with On-Board DC Power Stages

The board integrates multiple high-power DC modules to feed all four slots without relying on slot power alone, and it fits 2U server chassis where vertical clearance is tight. Signal-enhancement circuitry is built in to preserve integrity across the full x16 span, and the adapter presents a single DB9 RS-232 changer interface for legacy management or debug cabling.

Upgrades Single-Drive PCIe Add-In Cards

When a platform supports PCIe bifurcation, this card replaces a lone NVMe riser and unlocks four concurrent drives with an aggregate ceiling above 10000 MB/s. On boards that cannot split the x16 link, only one drive will be visible, so the upgrade is worthwhile only after confirming channel-splitting capability with the motherboard vendor.

Questions about this item

What PCIe standard and lane width does the PLX8724 adapter use?

It connects through a PCIe 3.0 x16 slot and splits the lanes to four M.2 NVMe ports.

What physical slot and chassis clearance does the card require?

A full-height PCIe x16 slot and enough space for a quad M.2 board; it fits 2U server chassis.

How is the adapter installed and what BIOS step is often missed?

Insert into a PCIe x16 slot, attach up to four M.2 NVMe drives, then enable PCIe bifurcation in the motherboard BIOS so all four drives are detected.
