Eight SATA III expansion card

This PCI Express card adds eight SATA III 6 Gbps ports through a single x4 Gen 2 slot using four 2-port host controllers and a PCIe multiplexer. It suits desktop or server builders who need more internal drive connections than the motherboard provides.

Throughput limited by PCIe x4 Gen 2

The x4 Gen 2 link caps combined bandwidth at 16 Gbps, so eight drives at full 6 Gbps each cannot run simultaneously at peak speed. Older SATA I or II drives and PCIe Gen 1 slots work but at lower performance.

Low-profile bracket with locking cables

The card measures 5.90 by 2.70 by 0.60 inches and weighs 2.50 oz, fitting standard low-profile brackets. Two Mini SAS ports connect to four Mini SAS to locking SATA adapter cables for secure drive attachment.

Questions about this item

Should I choose the eight external SATA III ports or the two internal Mini SAS ports?

The card provides both simultaneously — eight external SATA III ports fed by two internal Mini SAS connectors, each Mini SAS breaking out to four locking SATA cables.

What does the 6Gbps per port figure mean when the card sits in a PCIe x4 Gen 2 slot?

Each of the eight SATA III ports can run at 6Gbps, but the shared PCIe x4 Gen 2 link caps combined throughput at 16Gbps, so all eight ports cannot sustain peak speed at once.

Does the PCIe x4 Gen 2 interface limit the SATA III 6Gbps ports in practice?

Yes, the x4 Gen 2 slot delivers up to 16Gbps total bandwidth, which is shared across all eight SATA III 6Gbps ports, so aggregate throughput cannot exceed that ceiling.
