This is the plain forward breakout: no sideband wiring, no extra lead, just four clean links between the controller and four drives.\u003c\/p\u003e\n\u003ch2\u003eWhy this is the version most builds need\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eForward, not reverse.\u003c\/strong\u003e SFF-8643 sits on the host side here — the controller or the board — and the four 7-pin ends go to the drives. A backplane is the opposite case: its 8643 is a socket that has to be fed, which takes the reverse breakout. Getting this wrong is the single most common reason a breakout cable appears dead on arrival.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo sideband, so nothing to leave dangling.\u003c\/strong\u003e Plenty of cables ship with a little extra flying lead for the connector’s sideband pins. In a desktop build that lead either gets cut off or rattles around the case. This version does not have one, which also makes it the cheaper of the two 100 cm breakouts we stock.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour links that stay four links.\u003c\/strong\u003e There is no expander and no port multiplier inside. Each drive keeps its own 6 Gb\/s link, so four drives show up as four devices and can fail, be replaced or be left empty independently.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOne metre of reach.\u003c\/strong\u003e Enough to cross a full-size tower, reach a 4-in-3 cage at the front of the case, or put drives on a bench next to an open chassis.
