PCIe 3.1 x8 to Dual M.2 NVMe SSD Expansion Card

The PCIe 3.1 x8 to Dual M.2 NVMe SSD Expansion Card allows a desktop computer to connect two M.2 PCIe NVMe solid-state drives through a single PCI Express expansion slot. It uses the ASMedia ASM2812 chipset and is designed for high-speed storage expansion and multi-drive configurations.

Key Features

• Supports two M.2 PCIe NVMe solid-state drives.
• Provides two M.2 M-Key slots.
• Uses a PCI Express 3.1 x8 host interface.
• Supports PCIe 3.0 M.2 SSDs.
• Equipped with the ASMedia ASM2812 chipset.
• Offers a combined transmission rate of up to 3.5GB/s.
• Suitable for storage expansion, high-speed data transfer, and workstation use.
• Supports independent access to two installed NVMe drives.
• Compact expansion-card design for desktop computers.

Compatibility

This adapter is intended for M.2 PCIe NVMe SSDs with an M-Key connector. It is not designed for M.2 SATA drives or M.2 drives that use a B-Key or B+M-Key interface unless explicitly supported by the manufacturer.

The installed SSDs must use compatible physical dimensions. Check the enclosure and mounting positions before installation, particularly when using M.2 2242, 2260, or 2280 drives.

Performance

The card supports a maximum combined transmission rate of up to 3.5GB/s. Actual performance depends on the installed SSDs, PCI Express slot configuration, motherboard capabilities, operating system, and workload. The available bandwidth may be shared between both M.2 drives.

Applications

• Adding two NVMe SSDs to a desktop computer.
• Expanding high-speed storage capacity.
• Building workstation and content-creation systems.
• Improving storage performance for demanding applications.
• Connecting multiple PCIe 3.0 M.2 drives through one expansion card.
