The PCIe 4.0 SlimSAS 4i (SFF-8654) to 2 U. 2 (SFF-8639) Cable enables high-performance storage expansion by converting a single SlimSAS x4 host port into dual U. 2 NVMe SSD connections. Supporting blazing PCIe 4.0 speeds (16 GT/s per lane), it delivers up to 64Gbps total bandwidth for data-intensive applications. The cable's shielded design ensures signal integrity, while its hot-pluggable U. 2 connectors simplify enterprise storage upgrades. Backward-compatible with PCIe 3.0, it works seamlessly with major NVMe SSDs (Intel, Samsung, Micron). Perfect for servers, storage arrays, and NVMe RAID setups, this cost-effective solution doubles your storage capacity without requiring additional PCIe slots.
