The Sunweit ST584 Dual U.2 NVMe PCIe Adapter provides a straightforward way to install two enterprise or workstation-class 2.5-inch U.2 NVMe SSDs in a compatible PCI Express system.

The card features two integrated SFF-8639 U.2 connectors, allowing the SSDs to mount directly to the adapter rather than relying on separate drive bays and U.2 cabling. The ST584 connects through a PCIe x8 edge connector and is suited to storage expansion in desktop PCs, workstations and compatible server platforms.

Please check your motherboard’s PCIe configuration and NVMe support before purchasing, particularly when installing two drives.
