This SI-PEX40139 PCIe SATA controller card adopts mature JMB585 chipset and PCIe X4 bus design, delivering five separate SATA 3.0 channels with maximum 6Gbps high-speed transmission to expand your desktops storage interfaces. Built in non-RAID mode, every connected hard disk and solid-state drive works separately without complicated array configuration, and the card allows installing operating systems directly on linked SATA storage devices. It can be plugged into PCIe X1/X4/X8/X16 slots of mainstream motherboards without bandwidth bottlenecks. A removable low profile metal bracket is included for flexible installation in both regular full-tower PCs and compact mini ITX chassis.

Optimized anti-interference circuit ensures stable signal output during long-duration multi-disk simultaneous read-write work. Backward compatible with SATA I and SATA II storage hardware, matching drivers cover all common Windows and Linux versions for quick plug-and-play setup. It is a cost-effective storage upgrade for daily desktop use, light data backup, small surveillance recording hosts and mini DIY NAS equipment.
