iomgui Posted February 2, 2020 Share Posted February 2, 2020 My problem is simple, my motherboard Z390M gaming from gigabyte has 1 PCIe 16x and 1 PCIe 4x along with a couple PCIe 1x. Considering my case (CS381) and space available, i can only use the PCIe 16x for my graphic card. Wich means i can only connect my (not received yet, i can still cancel) LSI 9211 8i controller to the PCIe 4x port. I read everywher that it should be plugged into a 8x Pcie and never in a 1x PCIe. But what about a 4x PCIe ? What would be the conséquences in case of 8 HDD ? 1/ no consequences as with unraid only 3 hdd would work at the same time ? if i simplify … 2/ no consequences as long as i only plug 4 HDD, and for 8HDD what would be the result ? half speed ? worse ? 3/ consequences even with 4hdd ? 4/ other ?

Vr2Io Posted February 2, 2020 Share Posted February 2, 2020 9211-8i are PCIe2.0 card, if run in 4x PCIe2.0 still no bottleneck for 8 HDDs. Quote Link to comment
