Hey guys, is it ok if I use a LSI HBA card for Pcie 1x slot? My 16x slot is being used by my 8x NIC and my motherboard does not support difurcation. I planned to have two LSI HBA card on my two 1x PCIE slot, is it safe to have drives running on two LSI HBA card?

    There will be bottlenecks?

    Probably? Maybe? ¯⁠\⁠_⁠(⁠ツ⁠)⁠_⁠/⁠¯ didn’t give a whole lot of information

    PCIe 1x use 1gb/s

    Pcie gen 3.0 x1 is 1GBps. Is both your slot AND your card gen 3 or higher? Older cards are usually gen 2

    4 x 200 mb/s = 800 mb/s

    Yes that is how that would work assuming the card uses gen 3… Although given the fact that you said theres 1 SAS port, I doubt its gen 3. Single port cards were mainly a thing on SAS 1/2 cards, which predominantly used PCIe gen 2.
