Two SATA 3.0 ports for PCI-E systems

This KEERUN expansion card adds two SATA 3.0 7-pin connectors through a single PCI-Express x1 slot. It suits builders who need extra internal drive connections on a motherboard with limited native SATA headers. The card works with Windows 7 through 10 and Linux operating systems.

PCI-E 2.0 link caps real throughput at 6.0 Gbps

The adapter complies with the PCI-Express v2.0 specification and the Serial ATA 3.0 specification, so the bus can signal at 6.0 Gbps, 3.0 Gbps or 1.5 Gbps. Because the SATA lanes are converted from the PCI-E link, actual transfer rates fall short of the drive’s rated maximum, a limitation shared by every SATA expansion card of this type.

Low-profile PCB weighs .05 kg and fits any x1 slot

The board uses PCI-E 3.0 wiring and is backward compatible with PCI-Express v1.0 slots, accepting x1, x4, x8 or x16 physical connectors. Two standard SATA data ports support AHCI 1.0, IDE mode, NCQ and hot-swap operation, while the lightweight construction places minimal stress on the motherboard slot during daily use.

Questions about this item

Should I pick the 2-port or 4-port version of this card?

This listing is for the 2-port SATA3.0 expansion card; the 4-port model is a separate product.

Will my SSDs hit the full 6.0 Gbps SATA III speed through this card?

The supplier notes that PCI-E conversion causes signal loss so drives will not reach their nominal 6.0 Gbps rating.

Does the PCI-E x1 slot limit the card to PCI-Express 2.0 speeds?

The card complies with PCI-Express v2.0 and is backward compatible with v1.0, capping the bus at that generation.
