Product Features
Technical Overview
The DUAL-M2-PCIE-CARD-B leverages PCI Express 4.0 technology to maximize throughput, supporting two M.2 SSDs simultaneously. It requires PCIe bifurcation on the motherboard, which splits the PCIe lane into two x4 connections for each drive. This ensures full bandwidth utilization for NVMe or AHCI drives, making it ideal for data-intensive applications like video editing, virtualization, or database management.
Compatibility is extensive, covering popular SSD models such as Samsung 980 Pro, 970 EVO, 950 EVO, and SM951, along with other 2242/2260/2280/22110mm PCIe M-Key drives. The adapter is not compatible with SATA-based M.2 drives, focusing solely on PCIe interfaces. Backwards compatibility with PCIe 3.0 motherboards is supported when bifurcation is available, maintaining performance in older systems.
Relevant factors for this section include Color Family, Product Color, Height, Package Contents. When those points are considered together, they give buyers a clearer picture of how the product is equipped, how it fits into deployment, and what kind of day-to-day role it is meant to support.

Deployment / Use Cases
The DUAL-M2-PCIE-CARD-B is versatile for various professional and enthusiast scenarios. In workstations, it allows editors and designers to add fast scratch disks or project storage, reducing render times and improving workflow efficiency. For servers, it provides an economical way to integrate high-speed NVMe storage without requiring native M.2 slots, ideal for virtualization hosts or database servers.
Gamers and PC builders can use this adapter to expand storage in systems where motherboard M.2 slots are limited or occupied. The low-profile bracket option makes it suitable for small form factor (SFF) cases, while the full-profile bracket fits standard ATX towers. IT departments benefit from the adapter's compatibility with mainstream operating systems, simplifying deployment in mixed environments.
Workstation Upgrade
Add high-performance storage for video editing, 3D rendering, or scientific computing, leveraging PCIe 4.0 speeds.
Server Storage Expansion
Integrate NVMe drives into servers for faster data access in virtualization, database, or file-sharing applications.
Physical Profile

User Manual
FAQ
Does this adapter require PCIe bifurcation on the motherboard?
Yes, PCIe bifurcation is required for the adapter to function correctly. Bifurcation splits the PCIe lane (x8 or x16) into two x4 connections, allowing both M.2 slots to operate simultaneously. Most modern motherboards support bifurcation, but check your motherboard's BIOS settings or manual to confirm availability, especially for PCIe 3.0 systems.
What is the maximum data transfer speed per drive?
Each drive slot supports speeds up to 7.8GBps (gigabytes per second) when used with compatible PCIe 4.0 NVMe SSDs and a PCIe 4.0 motherboard. Actual speeds depend on the SSD model, motherboard capabilities, and system configuration. With PCIe 3.0, speeds are lower but still benefit from high-performance drives.
Can I use this adapter in a PCIe 3.0 slot?
Yes, the adapter is backwards compatible with PCIe 3.0 motherboards, provided they support PCIe bifurcation and have an available x8 or x16 slot. Performance will be limited by PCIe 3.0 bandwidth, but it remains a viable option for adding M.2 storage to older systems without native M.2 support.
What is included in the package?
The package contains the PCIe to M.2 adapter card, one low-profile (half-height) bracket (with a full-profile bracket pre-installed), a quick-start guide, and a set of mounting screws. The vented brackets help with airflow to prevent overheating, and the screws secure M.2 drives to the adapter.
What connectivity or interface options are available?
Connectivity details help confirm how StarTech.com PCIe to M.2 Adapter Card (DUAL-M2-PCIE-CARD-B) can integrate with your network, accessories, and surrounding peripherals before rollout or replacement planning.
What form factor or physical profile is listed?
The listed physical configuration is 0.87" (22 mm), which helps buyers judge placement, comfort, or installation fit in the intended environment.
