PCIe to 2 Port SATA III Card

This expansion card adds two SATA III 6Gbps ports to a desktop computer through any available PCI Express x1, x4, x8 or x16 slot. It uses a Marvell 9125 controller and complies with SATA 3.0, 2.0 and 1.0 specifications. The board supports AHCI and IDE modes with Native Command Queuing for improved drive performance.

Suits builders adding SATA drives

Ideal for users who need extra SATA connections for hard drives or SSDs on a system with a free PCIe slot. It supports hot-plug and hot-swap operation, Gen 1i through Gen 3i speeds, and Port Multiplier switching. Not suited for users who need more than two SATA ports or who require a different host interface than PCI Express.

Requires PCIe x1 slot version 2.0

The card fits any PCIe x1, x4, x8 or x16 slot but needs a PCI Express 2.0 link to reach full 6Gbps throughput; a 1.0 slot limits speed to 250MB/s. Compatible with Windows 10, 8, 7, Vista, XP, Server 2003, 2008 and Linux in both 32-bit and 64-bit versions.

Questions about this item

How do I install the weastlinks PCIe to 2 Port SATA III card and what slot mistake should I avoid?

Insert the card into any PCI‑Express x1, x4, x8 or x16 slot that is version 2.0; a version 1.0 slot limits speed to 250 MB/s and will not deliver full 6 Gbps performance.

What maintenance or replacement will the card need later?

The Marvel 9125 controller and SATA ports are solid‑state with no moving parts; only the SATA data cables may wear and need replacement over time.

What limit appears first under sustained heavy use?

The PCI‑Express x1 host link caps total throughput, so both SATA 6 Gbps ports share that bandwidth ceiling during continuous transfers.
