This all-in-one U.2 NVMe storage expansion kit includes a PCIe x4 to SFF-8643 Mini SAS HD adapter card and a dedicated SFF-8643 to SFF-8639 U.2 cable, designed to add external 2.5-inch U.2 NVMe SSDs to motherboards without native U.2 headers.
The PCIe x4 adapter card adopts high-quality PCB with built-in SFF-8643 female port, fully compliant with PCIe 3.0 and backward compatible with PCIe 4.0, delivering complete x4 lane bandwidth without performance loss. Equipped with a removable full-height metal bracket, it can be firmly installed in standard PCIe expansion slots of desktops, editing workstations and rack servers.
The matched SFF-8643 to SFF-8639 cable uses multi-layer EMI shielding and gold-plated contact pins to cut electromagnetic interference and resist oxidation, maintaining consistent low-latency data transfer for mass file rendering, database storage and enterprise data backup.
No extra driver installation required, the whole kit is plug and play on Windows and Linux server systems, widely compatible with all mainstream SFF-8639 U.2 NVMe SSDs such as Intel 750/P3600/P3700 series. It is an essential upgrade accessory for DIY high-speed storage arrays, video production workstations and small enterprise storage expansion projects.
