PCI-E 2.0 lane -> PCI-E 1.0 converter -> PCI-E 2.0 card means performance hit?

Hi guys,

I am setting up a HP DL-120 with a HP P410 raid card.

The problem is that the raid card uses PCI-E 2.0 and in order to insert it into the server I can use a PCI-E 1.0 converter (to make the card lay parallel with the mainboard) into a PCI-E 2.0 lane on the mainboard.

So my question is simple: Will there be a performance hit for using the PCI-E 1.0 converter?

  1. No. The PCIe 1.0 has enough bandwidth. You dont need a converter. A pci 2.0 card will fit in PCIe 1.0
  2. I don' think, it is a converter of any sort. It is a simple mechanical raiser card and that's the same for pci-e 1.0 and 2.0.
  3. Hi Random_G33k,

    The reason I need a converter is to make the card lay parallele with the main board to fit in the 1U. So Im wondering if I need to get a dedicated PCI-E 2.0 converter. The disks are 15k SAS drives so I need to make sure there is enough bandwith..

    PCI 1.0 has bandwidth of 250MB/s per lane. I think its fast enough. PCIe 2.0 has bandwidth of 500MB/s per lane.
