5 Port PCIe X4 SATA 3.0 Non-RAID Controller Card SI-PEX40139 with JMB585 Chipset, 6Gbps Storage Adapter for SSD & HDD, Low Profile Bracket Included

This SI-PEX40139 PCIe X4 SATA 3.0 expansion controller card is built with high-performance JMB585 chipset, providing five separate SATA 6Gbps channels to expand storage capacity for desktop PCs, mini workstations and small NAS.

Non-RAID architecture enables independent operation of every connected SSD and HDD without complicated array configuration, and the card supports booting operating systems directly from attached SATA storage devices. Powered by PCIe X4 bus, it eliminates bandwidth bottlenecks even when all five drives execute simultaneous read-write tasks for data backup, surveillance recording and light rendering workloads.

A removable low profile metal bracket is included for flexible installation, perfectly fitting compact small-form-factor computers and regular full-size tower cases. Optimized anti-interference PCB layout effectively reduces signal crosstalk and guarantees 24-hour stable continuous operation under full load.

The card works seamlessly with 2.5-inch solid-state drives and 3.5-inch mechanical SATA hard drives, backward compatible with legacy SATA 1.0 and SATA 2.0 hardware. Complete matched driver packages support mainstream Windows and Linux operating systems for fast plug-and-play setup. It is a cost-effective storage expansion solution for DIY desktop hosts, office backup workstations and lightweight personal NAS devices.
