Identify PCIe slots on the motherboard

Hi,

can someone help me identify these slots, I know they are PCIe, but they are different from the black slot. Also can they be used for an SSD?

The other slots are traditional PCI, although I'm not sure specifically the difference for that small notch on the middle slot. Despite sharing the PCI part of the name it's a completely different standard and significantly slower, you wouldn't want to put a SSD on them. Normal PCI had something like 133 MB/sec shared bandwidth for the entire bus (more cards = slower bus) and was half duplex.

Thanks.

If your mobo still has PCI slots, it's probably not going to support SSD storage through nvme via PCI-E slot.

NVME support is "relatively" new... around the time of the Z97 chipset era for Intel boards. Which is way past the PCI days.
