PCIe 4.0 x8 to Dual U.2 SFF-8639 SSD Adapter Supports 2 x U.2 NVMe SSDs, PCIe Bifurcation Required (x4x4), for Intel VROC, AMD RAID, Workstation & Server

Dual U.2 NVMe SSD Expansion: Adds two independent U.2 (SFF-8639) NVMe SSD slots via a single PCIe 4.0 x8 slot, enabling high-performance storage expansion for workstations, servers, and data-intensive applications.
PCIe 4.0 x8 Interface: Delivers up to 64Gbps bandwidth per SSD (x4 lanes each) when paired with PCIe 4.0-compatible CPU, motherboard, and SSDs, providing ultra-fast data transfer for demanding workloads.
PCIe Bifurcation Required: Requires motherboard support for PCIe bifurcation with x4x4 or x4x4x4x4 mode on the PCIe x8/x16 slot (not compatible with x8x4x4 mode). Consult motherboard manual before purchase.
VROC & Soft RAID Ready: Supports Intel VROC (Virtual RAID on CPU) with license purchase, as well as software RAID configurations on Intel and AMD platforms for storage pooling and redundancy.
OS Boot Support & Plug-and-Play: Supports booting from U.2 SSDs on compatible systems; plug-and-play in Windows 10/11, Linux, and macOS (Windows 7 not supported). Includes long metal bracket for full-height chassis.

Maximize your system's storage performance with this PCIe 4.0 x8 to Dual U.2 SFF-8639 SSD Adapter. Designed for workstations, servers, and high-performance computing environments, this adapter allows you to install two U.2 NVMe SSDs from a single PCIe x8 slot, delivering blazing-fast storage for data-intensive applications such as video editing, 3D rendering, virtualization, and database workloads.

High-Performance PCIe 4.0 Interface

When paired with PCIe 4.0-compatible components, each U.2 SSD receives x4 PCIe 4.0 lanes, delivering up to 64Gbps (8GB/s) of theoretical bandwidth per drive. This ensures maximum throughput for high-speed NVMe storage, enabling rapid file transfers, low-latency access, and smooth multitasking.

Important: PCIe Bifurcation Requirement

This adapter is a passive signal routing device and does not include a PCIe switch. It requires your motherboard to support PCIe bifurcation (lane splitting) to recognize both U.2 SSDs. The motherboard's PCIe x16 or x8 slot must be configured to x4x4 or x4x4x4x4 mode. x8x4x4 mode is NOT supported.
