PCIe 4.0 x4 Male to M.2 NVMe Key M 2280 SSD Extension Cable, 85-ohm Low Impedance

The PCIe 4.0 x4 Male to M.2 NVMe Key M 2280 SSD Extension Cable is a high-performance interconnect solution designed for enterprise storage, data centers, and high-performance computing environments . This cable provides a direct electrical extension from a PCIe 4.0 x4 host slot to a remote M.2 NVMe SSD, specifically supporting the common 2280 form factor . It is engineered to deliver the full bandwidth of PCIe 4.0, supporting high-speed data transmission for NVMe SSDs while enabling flexible drive placement for improved thermal management or space-constrained configurations .

Features

• Precision 85-ohm Impedance: Engineered with controlled low impedance to minimize signal reflections and ensure data integrity at PCIe 4.0 speeds .
• Full PCIe 4.0 Performance: Supports data rates up to 16 GT/s per lane, delivering a total bandwidth of up to 64 Gbps for maximum NVMe SSD performance .
• Dedicated 2280 SSD Support: Designed for the widely used M.2 2280 form factor, with compatibility for other lengths such as 2230, 2242, and 2260 through adjustable mounting .
• Robust Construction: Utilizes quality shielded cabling, such as FPC (Flexible Printed Circuit) or PVC-insulated cables, with effective EMI/RFI protection for stable operation .
• Secure Connection System: Features durable, latching connectors to ensure reliable mating and prevent accidental disconnection .
• Flexible Cable Design: The cable is lightweight, flexible, and shock-resistant, facilitating easier routing within computer cases .
• Protocol Specific: Functions as an extender, supporting NVMe to NVMe or SATA to SATA extension from the host to the target device, but does not perform protocol conversion between NVMe and SATA .
