Use this assembly to attach Gen5 MCIO devices — NVMe adapter cards, front bays, backplanes — to a controller or switch card that still speaks SlimSAS. It is the mirror image of the MCIO-to-SlimSAS fanout and covers the transition window where both standards live in the same chassis.\u003c\/p\u003e\n\u003ch2\u003eWhy this cable\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePCIe 5.0 rated, 32 GT\/s per lane.\u003c\/strong\u003e Two full x4 links, each up to about 15.75 GB\/s;
