Dual 2.5G Ethernet and NVMe adapter

This card adds two 2.5 gigabit network ports and two M.2 NVMe slots through a single PCIe 3.1 x4 connection. It targets builders who want faster wired networking and extra solid-state storage without occupying multiple expansion slots. The ASMedia ASM2812 chipset manages both functions independently.

Check slot width and drive keys

Your motherboard needs a free PCIe x8 or x16 slot that can operate at x4 electrical or higher. Only M-key NVMe SSDs in 2230, 2242, 2260, 2280 or 22110 lengths are supported; SATA or AHCI drives will not work. Older boards may not boot from NVMe, so verify firmware capability first.

Sustained throughput with independent lanes

Each NVMe drive receives its own PCIe 3.1 x4 path so heavy storage traffic does not contend with the dual 2.5G Ethernet controllers. The adapter draws power from the slot and includes a low-profile bracket for compact chassis. Thermal monitoring is provided by an onboard sensor with an LED indicator.

Questions about this item

Does the box include the two 2.5G network ports and the four M.2 NVMe slots, or must I buy the SSDs separately?

The card provides dual 2.5G Ethernet ports and four M.2 slots for 2230, 2242, 2260, 2280 and 22110 NVMe drives; SSDs are not included.

Which M.2 lengths does the ASM2812 chipset support on this PCIe 3.1 x4 card?

The adapter accepts 2230, 2242, 2260, 2280 and 22110 M-key NVMe SSDs; SATA or AHCI drives are not supported.

What real throughput can I expect from each 2.5G port and each NVMe slot when the card runs in a PCIe 3.1 x4 slot?

Each 2.5G port tops out at 2.5 Gbps; each NVMe slot receives a dedicated PCIe 3.1 x4 link, so SSD speed is limited only by the drive and the motherboard's PCIe 3.0/3.1 bandwidth.
