Does each slot of PEX2PCI4 provide full speed PCI? - StarTech.com IT Pro Community
<main> <article class="userContent"> <p>No, you cannot get the full speed of PCI from each slot. PCI operates at a maximum speed of 266 MBps at 66 MHz or 133 MBps at 33 MHz. This enclosure features a PCI Express (PCIe) x1 slot (v. 1.0) that operates at 250 MBps.</p><p>The available bandwidth from the PCIe bus is split equally between the PCI slots, regardless of whether or not a card is inserted into each slot. The PCIe bus provides speeds up to 62.5 MB/sec per slot. This speed is sufficient for many PCI cards, but may impact the performance of higher-speed cards (for example, USB 3.0 PCI cards). </p> </article> </main>
