Same for SATA 3.0, which was released in 2009. Was PCIe 1.0a thrown under the bus? USB 3.0 came around in 2008, so I'd have figured there would have been plenty of interested parties making multi-lane upgrades for PCIe 1.0a, assuming it is possible.
Again, it is targeting PCIe 2.0 upgrades, not really PCIe 1.0a upgrades. There is such a combo card, but when inspecting it further, only 2 lanes are connected, and one is for USB 3.0, the other for SATA 3.0. Better yet would be a USB 3.0/SATA 3.0 combination card which was keyed for x4 or x8, and has each USB and each SATA port utilising 2 lanes. I was thinking that to optimise the buses, PCI = 1 gigabit ethernet PCIe-x1 = USB 3.0 PCIex16 = SATA 3.0, but again, with each port utilising at least 2 lanes. Currently the system has 4 GB of RAM and is using an HD4650 AGP graphics card.

I'd like to keep XP driver support, so most of those newer Adaptec cards are out of consideration even if they had multi-lane port allocation. It currently dual boots XP and Ubuntu 16.04LTS, but spends 99% of its time in Ubuntu. My ASRock 939Dual-SATA2 has three PCI, one x1, one x16 slot, and one AGP 8x slot. I was also hoping for a 3- or 4-port USB 3.0 card with each port utilising at leats 2 lanes. I was hoping for a 4-port SATA 3.0 card with each port utilising at least 2 lanes. It currently has 16 GB of RAM, but can be upgraded to 32 GB. I'd like to keep OS X 10.11 driver support though.

Currently dual boots Mac OS 10.11 and Ubuntu 16.04, but spends 99% of its time in Ubuntu. My MacPro 1,1 has two x4 slots, one x1 slot, and one x16 slot. Proper allocation of lanes could allows these systems to better utilise the SATA 3 and USB 3 protocols. As SSD prices drop like mosquitos on a scorching hot day in northern Ontario, I see 4 TB SSDs in the forecast for these systems. My ASRock 939Dual-SATA2 is one example, and my MacPro 1,1 desktop with dual Xeon X5365, 3 GHz CPUs is another. It appears to me as if most of these USB 3.0 and SATA 3.0 upgrades are targeting PCIe 2.0 installations, which is unfortunate because PCIe 1.0a was around for 4 years before PCIe 2.0 and many motherboards with PCIe 1.0a already had SATA 2.0/USB 2.0 and could benefit from SATA 3.0/USB3.0. Is it not possible to use multi-lane traffic for USB/SATA like with graphic cards? Upon reading the specifications, it seems that they are only allowing one lane per port as well. There are also some no-name SATA 3.0 cards which have an x4 connector, but if you inspect the traces more closely, you'll discover that only 2 lanes are connected. I can find SATA 3.0 cards (Adaptec ASR-6805T) in x8, but I suspect each port gets a dedicated lane. The slot is x4, but each port only uses one lane. The best examples I can find today are of a USB 3.0 card with 4 ports.

Do any PCIe upgrade cards allow for multi-lane traffic on a single port to increase throughput?
Were there any multi-lane PCIe cards for USB 3.0 and SATA 3.0 which utilised more than one lane per available port? When I see photos of PCIe x4 or x8 card, I am noticing that the lanes tend to be dedicated to particular USB 3.0 port or SATA port.
