Dual M.2 NVMe adapter for PCIe 4.0 x16 slots

This adapter card adds two M.2 NVMe SSDs to a single PCIe 4.0 x16 slot using x8 x4 x4 bifurcation. It supports M.2 2230 2242 2260 and 2280 drives and remains backward compatible with PCIe 3.0 platforms. The card targets builders who need extra high-speed storage without occupying additional expansion slots.

Bifurcation-dependent performance under load

Sustained transfer rates rely on motherboard BIOS support for PCIe bifurcation; without it only one SSD will be detected. The open frame PCB layout provides passive cooling to help maintain stable data throughput during prolonged workloads. Peak sequential speeds up to 7500 MB/s vary with the installed SSDs and system configuration.

Full height and low profile brackets included

Both bracket sizes ship in the box allowing installation in standard ATX towers or small form factor cases. The controller card uses a 4-layer PCB for signal integrity and features front and back M.2 slots for dual drive mounting. Builders who need a hardware PCIe switch or support for more than two drives cannot use this card.

Questions about this item

Does the open-frame PCB keep the 7500 MB/s drives cool during all-day workloads?

The open-frame design provides passive cooling to prevent thermal throttling during heavy sustained workloads.

My motherboard must support PCIe bifurcation for both 2280 NVMe SSDs to appear, correct?

Yes, the card needs BIOS bifurcation support or only one SSD will be detected.

Can I run a PCIe 3.0 NVMe drive alongside a PCIe 4.0 NVMe drive on the x8 and x4 lanes?

The adapter is backward compatible with PCIe 3.0 and allocates x8 to the primary slot and x4 to the secondary slot.
