Dual NVMe PCIe 3.1 x8 Adapter

This RIITOP expansion card adds two M.2 NVMe SSDs to a desktop workstation or server through a PCI Express 3.1 x8 slot. It uses an ASMedia ASM2812 controller to deliver up to 3.5 GB/s and 3.2 GB/s sequential speeds for a single drive. The card fits standard and low-profile brackets for wide chassis compatibility.

Suits builders adding fast storage to servers

It suits users who need two NVMe drives in a single PCIe 3.0 x8 or x16 slot and want RAID 0, 1 or JBOD managed by the operating system or third-party software. Builders with only PCIe 2.0 or 1.0 slots will see reduced throughput. Systems without an x8 or larger slot cannot use this card.

PCIe 3.1 x8 host interface

The card requires a PCI Express 3.0 x8 or x16 slot to reach its stated speeds; performance drops on 2.0 or 1.0 links. It accepts M.2 2230, 2242, 2260, 2280 and 22110 NVMe SSDs with M-key pinout. Adjustable standoffs secure 30 mm, 42 mm, 60 mm and 80 mm drive lengths.

Questions about this item

Which M.2 form factors does this card accept?

The card fits 22110, 2280, 2260, 2242 and 2230 drives using adjustable stand-offs and multiple mounting holes for 80mm, 60mm, 42mm and 30mm lengths.

What single-drive throughput can I expect from a PCIe 3.0 NVMe SSD installed here?

A single drive can reach 3.5GB/s read and 3.2GB/s write when the card sits in a PCIe 3.0 x8 or x16 slot.

What does the PCIe 3.1 x8 interface limit in practice?

The x8 link caps aggregate bandwidth to the PCIe 3.0 ceiling, so two drives share that pool; in a 2.0 or 1.0 slot speeds drop proportionally.
