PCIe Transfer Speed

[Stoigeboiii]

I am looking into hard drive solutions and saw the Intel Optane 900p and I'm confused because I thought that PCIe ports werent fast. Any information?

PCIe ports are, in fact, very fast. A PCIe  x4 connection offers almost 4 gigabytes a second. You may be thinking of PCI, the previous common connector. That's very slow.

Just pulled this off google. May or may not be totally accurate but yes PCI_e is very fast. It's predecessor PCI is quite a bit slower but compared to an HDD it still has quite some pep.

What does the x4 and x16 mean?

these are standard PCIe ports on a motherboard, and they are labelled with the link sizes. An m.2 uses a mini version of the x4. It's basically the amount of pins.
