Storage Expansion

This PCIe 5.0 x16 adapter converts a single slot into two MCIO x8 connectors, allowing up to four U.2 NVMe SSDs to be attached. It targets workstation builders and server operators who need dense, high-speed local storage without occupying multiple expansion slots.

Installation Notes

The card is a plug-and-play device and ships with screws, a screwdriver and two mounting brackets to simplify fitting. The critical requirement is motherboard support for PCIe signal splitting or bifurcation; without it, only one drive will be recognised and the remaining ports will stay invisible to the system.

Compatibility Check

Verify that your motherboard firmware explicitly enables PCIe bifurcation on the intended x16 slot before ordering. Also confirm you have MCIO x8 to U.2 cables available, as they are not included with the adapter.

Questions about this item

How do I verify all four U.2 NVMe SSDs are detected after installing the LLS-CD-1PC2MC-04?

Check your motherboard BIOS or UEFI to confirm all four NVMe drives appear. The card splits a PCIe 5.0 x16 link into two MCIO x8 ports, so the board must support PCIe bifurcation; otherwise only one drive may be recognised.

What comes in the box and which extra parts are needed to connect four U.2 NVMe SSDs?

The package includes one PCIe 5.0 x16 to 2 MCIO x8 adapter card with screws, a screwdriver and two mounting brackets. You must purchase two MCIO x8 to U.2 cables separately to link up to four U.2 NVMe SSDs.

Which version of the LetLinkSo adapter should I choose for a PCIe 5.0 x16 slot and four U.2 NVMe SSDs?

Select the LLS-CD-1PC2MC-04 model with Side Top MCIO x8 connectors; it is built for a PCIe 5.0 x16 slot and provides two MCIO x8 ports to support four U.2 NVMe SSDs at up to 128 Gbps per drive.
