Four-drive NVMe adapter

This PCIe 4.0 x16 add-in card provides four M-key slots that accept 2242, 2260 or 2280 NVMe drives. It targets workstation and enthusiast builders who need to add high-speed solid-state storage without occupying existing M.2 sockets on the motherboard.

Check bifurcation support

Your motherboard must support PCIe signal splitting, often called bifurcation, to expose all four drives to the operating system. Without that capability only a single drive will be visible. The card fits a standard x16 slot and is backward compatible with PCIe 1.0 through 5.0 platforms.

No drives or cooling included

The package contains only the expansion card itself; NVMe drives and any required heatsinks or fans must be sourced separately. The supplier notes that a heatsink is highly recommended when installing PCIe 5.0 drives to maintain optimal temperatures.

Questions about this item

What comes in the box and do I need to buy heatsinks or fans separately?

The package contains one PCIe M.2 expansion card. No heatsinks or fans are included. The manufacturer recommends adding a heatsink for PCIe 5.0 SSDs or purchasing the fan-equipped version for better cooling.

Which version should I choose between the PCIe 4.0 x16 and PCIe 5.0 x16 models?

Choose the PCIe 4.0 x16 model if your motherboard provides a PCIe 4.0 x16 slot and supports bifurcation. Select the PCIe 5.0 x16 model if your platform has a PCIe 5.0 x16 slot and you want full 5.0 bandwidth for each of the four M.2 slots.

What does the 128 Gbps per M.2 SSD figure mean once the card is installed?

Each M.2 slot can deliver up to 128 Gbps when a compatible NVME drive is installed in a system that supports PCIe 5.0 x4 signalling. The combined bandwidth across all four slots reaches 512 Gbps.
