Green circuit board with silver PCI bracket and four black SATA ports

SMUGDESK

SMUGDESK SIL3114 PCI to 4 Port SATA Expansion Card

SKU CH-Q31Z-YZDAN

Adds four SATA ports through a single PCI slot using a SIL3114 controller for drives up to 3TB on Windows 8 and earlier systems

  • Genuine SIL3114 controller delivers stable legacy PCI expansion
  • Converts one PCI slot into four independent SATA ports
  • Supports hard drives up to 3TB capacity for storage growth
  • Fully compatible with Windows 8 and earlier operating systems
  • Standard PCI bracket enables easy installation in older desktops

Legacy PCI Storage Expansion

The SMUGDESK SIL3114 card adds four SATA ports to a single legacy PCI slot using the original SIL3114 controller chip. It is designed for older desktop PCs and industrial hosts that lack native SATA connectivity. Builders maintaining vintage systems or retrofitting industrial equipment will find this adapter a direct solution for multi-drive storage attachment.

Replacing Missing Onboard Ports

This card upgrades motherboards that have no SATA headers or too few for the required drive count. The jump is worth it when legacy hardware must accommodate larger 3TB hard drives for data backup or archival storage. It is not suited for systems requiring modern high-speed storage interfaces or boot support for newer operating systems beyond Windows 8 compatibility.

Sustained Multi-Drive Operation

The SIL3114 chip delivers stable performance during continuous read and write cycles across four independent drives. Thermal output remains low without active cooling, making it reliable for long-term deployment in enclosed industrial chassis. Bandwidth is constrained by the legacy PCI bus, so sustained throughput suits archival workloads rather than high-performance arrays.

Questions about this item

Will the standard PCI bracket fit my legacy desktop case?

The card uses a standard PCI bracket that matches traditional desktop and industrial chassis slots.

Do I need to load drivers before Windows 8 recognises the four SATA ports?

Windows 8 includes native support for the SIL3114 controller so the ports appear after the card is seated and the system boots.

Can I later swap the attached drives for larger models beyond the 3TB limit?

The SIL3114 chipset addresses drives up to 3TB; larger drives will not be fully recognised by this card.
