Four-slot PCIe 4.0 expansion

This LetLinkSo adapter adds four M-key M.2 NVMe slots to a single PCIe 4.0 x16 slot. It accepts 2230, 2242, 2260 and 2280 form-factor drives and is backward-compatible with PCIe 3.0, 2.0 and 1.0 systems. Builders who need to run four fast NVMe drives from one expansion slot will use this card.

Thermals and power

An onboard DC brushless fan directs airflow across the four SSD positions to lower operating temperatures during sustained transfers. The fan is described as ultra-quiet and draws power from the PCIe slot itself. No external power connector is required.

Included accessories

The package supplies only the expansion card; no mounting screws, thermal pads or software utilities are bundled. Buyers who need drive-securing hardware or drive-cloning tools must source them separately.

Questions about this item

How do I install the LetLinkSo LLS-CD-1PC4MT-03 into a PCIe 4.0 x16 slot and what step is often missed?

Insert the card fully into a PCIe 4.0 x16 slot and secure the bracket screw; the step often missed is connecting the fan power header so the DC brushless fan runs and cools all four M.2 SSDs.

What maintenance will the LetLinkSo LLS-CD-1PC4MT-03 need over time?

The onboard DC brushless fan should be cleaned of dust periodically to maintain airflow across the four M.2 slots; no other user-serviceable parts are on the card.

What limit appears first on the LetLinkSo LLS-CD-1PC4MT-03 during sustained heavy transfers?

The PCIe 4.0 x16 host link caps total throughput at 256 Gbps, so all four NVMe drives share that bandwidth ceiling under sustained loads.
