    WTB: Short SFF-8087 to 4xSATA with Sideband

    Have looked high and low for a ~20cm (or less) cable. I have one of appropriate length without sideband, but would like to have sb if possible. Literally the M14TQC hot swap cage is about 2 inches from the expander, so longer cables wind up blocking fan flow. Reconfiguring the expander...

    CSE-PTJBOD-CB3 Questions

    Hello all, Frequent lurker here. I think first time posting. Gradually putting together a larger post with my complete build, however I have a couple of loose ends. I’ve reviewed some of the threads on the CB3 but some info I haven’t found or I haven’t seen a direct comparison in my use case...
