R27SF 30cm U.2 SFF-8639 NVMe to PCIe 3.0 x4 Extension Cable, Up to 32Gbps High-Speed SSD Transfer Cord

This R27SF U.2 to PCIe 3.0 x4 riser extension cable is a professional dedicated interconnect wire for SFF-8639 U.2 NVMe enterprise solid state drives. It connects 2.5-inch U.2 NVMe SSDs to PCIe x4 expansion slots on motherboards, fully unlocking PCIe 3.0 x4 maximum bandwidth without performance drop.

The 30-centimeter short flat cable avoids redundant messy wiring in narrow PC, workstation and rack server enclosures, improving air circulation to reduce SSD overheating during continuous read-write tasks such as database operation, video rendering and mass data backup. The cable uses multi-layer shielding structure with precise impedance control to block internal hardware interference and sustain consistent transfer speeds.

Both ends adopt high-frequency gold-plated PCB boards to cut contact resistance and resist oxidation. Pre-set screw fixing holes allow firm installation to prevent loose connection caused by rack vibration. It is plug-and-play without extra drivers, compatible with Windows, Windows Server and Linux systems, and works with mainstream SFF-8639 NVMe SSD brands like Intel, Samsung, WD and Micron.
