A PCI-E to U.2 riser card is a type of adapter that will allow you to connect a U.2 solid-state drive (SSD) to your computer's or server's motherboard via a PCI Express (PCI-E) x16 slot.
What a card like this will do for you on a custom setup:-
This specific type of riser card facilitates the connection between two different standards:
-
::PCI-E 3.0 x16: This refers to the physical slot on the motherboard and the version of the PCI Express standard. The "x16" means the slot has 16 data lanes, offering a very high bandwidth. PCI-E 3.0 has a transfer rate of 8 GT/s (gigatransfers per second) per lane, which is why a x16 slot can support multiple high-speed drives.
-
::U.2 (SFF-8639): This is the connector type for enterprise-grade 2.5-inch NVMe SSDs. U.2 drives are known for their high performance and reliability, often used in servers and workstations.
-
While the card physically fits into a PCI-E x16 slot, it's important to understand a key technical requirement:
::PCIe Bifurcation: This is a motherboard feature that allows a single large PCIe slot (like a x16) to be split into multiple smaller slots (e.g., four x4 slots). For a riser card to support multiple U.2 drives, your motherboard's BIOS/UEFI must support and be configured for bifurcation.
Without this, the system may only recognize one of the connected drives, even if the riser card has multiple U.2 ports.
