Six SATA 3.0 ports via PCI-E x1

This expansion card adds six independent SATA 3.0 ports to a system through a single PCI-E x1 slot. It uses the ASMedia ASM1166 controller for reliable signal transmission and supports hard drives larger than 10TB and 12TB. The package includes both low-profile and standard-height brackets for flexible chassis installation. It suits desktop PCs, servers and mining rigs needing extra drive connections.

Bandwidth limited to one PCI-E x1 lane

The card communicates over a single PCI-E x1 link, so total throughput is capped by that interface rather than by the six SATA 3.0 ports themselves. All attached drives share this single upstream connection during heavy simultaneous access. The ASM1166 controller manages port multiplexing but cannot overcome the physical lane limit. Users should plan workloads with this aggregate ceiling in mind.

Verify slot clearance and drive power

Ensure the target chassis has a free PCI-E x1 slot and enough physical space for the chosen bracket height. Confirm the power supply provides sufficient SATA power connectors for every drive you intend to attach. The card requires no extra PCIe power cable but each drive needs its own power lead. Driver support is native in modern operating systems for plug-and-play operation.

Questions about this item

How many SATA 3.0 ports does the ASM1166 card provide for adding drives?

The card adds six SATA 3.0 ports, each able to connect one hard drive or SSD for a total of six additional storage devices.

Will the ASM1166 controller recognise hard drives larger than 10 TB or 12 TB?

Yes, the ASM1166 controller supports high-capacity hard drives over 10 TB and 12 TB, so very large drives are detected and usable.

What bandwidth limit does the PCI-E x1 link impose on the six SATA 3.0 ports?

The PCI-E x1 link caps total throughput to roughly one lane of bandwidth, so all six SATA 3.0 ports share that single-lane ceiling in practice.
