So basically PCI-e 2.0 has about 0.5 GByte/s per lane. The controller wants to have x8(for its max workload) that would be 4 GByte/s and with the x4 mode its 2 GByte/sec which should be fast enough for my HDDs. Ok thanks. I think I got it. I will get the LSI Megaraid 9201-8i 6G PCIe 2.0 x8 SATA/SAS HBA

Ok. What do you mean by limited bandwidth?

Hey guys, I'm just recycling my old desktop as an unraid NAS. I'm looking for an fitting SAS controller, but I'm not sure which one would work with my pcie ports . Probbaly someone could explain or recommend a bit. Here is the manual of my board. It states: If I can see it right. If I have my RTX 2060(want to use it for passthrough vm) in it which is set into the 1 x PCI Express 3.0 slot it covers all ports except the 1 x PCI Express 2.0 x16 and 2 normal PCI slots. The storage controllers I checked online Adaptec ASR-71605(needs PCI E 3.0) and LSI Megaraid 9201-8i 6G PCIe 2.0 x8 SATA/SAS HBA(needs PCI E 2.0 x8) won't work with the RTX in the system, right? I'm a bit confused with the * stuff in the manual. So are there proper alternatives? Thanks in advance, Juli
