SMUGDESK 8 Port PCIe x1 to SATA 3.0 Expansion Card

8-Port SATA Expansion Card

This PCIe x1 adapter adds eight SATA 3.0 ports to a desktop computer, enabling connection of multiple solid state drives or mechanical hard drives. It supports system boot from attached drives and works with standard SATA devices. The card fits any PCIe x1, x4, x8 or x16 slot for broad motherboard compatibility.

Upgrade from limited onboard ports

The card replaces the need for a motherboard with many native SATA connectors, letting you add large drive arrays to boards that only offer a few headers. The jump is worth it when you require more than the standard four to six ports for storage expansion or RAID configurations. It also serves systems where onboard controllers have failed or lack boot support for additional drives.

PCIe x1 bandwidth ceiling

The single-lane PCIe x1 link caps total throughput across all eight ports, so sustained transfers on several drives at once will share the same bus limit. SATA 3.0 devices can each reach 6Gbps, but the aggregate speed cannot exceed the host slot's capacity. Builders needing full simultaneous bandwidth on every port should consider a multi-lane controller instead.
