PCIE 1.0 supports up to 4x faster networking speeds.
You're looking for the quickest networking option for your Haswell machine's PCIe slot. Based on your setup, PCIE 2.0 4X supports speeds up to 10 gigabit, so you're likely aiming for something between 2.5 and 6 gigabit. Since you'll be using WD Red Plus drives in RAID 5, SATA RAID0 might be a practical choice for large file transfers.
Based on available data, PCI_e x4 Gen 1 might handle up to 1GB/s in theory. In practice, real-world speeds are probably lower.
PCIe standards vary across generations, with each version offering different transfer speeds. The rates change based on the specific network card being used rather than just the theoretical maximum of the port.
