Green PCB card with two black SATA ports and metal bracket

SMUGDESK

SMUGDESK PCIe to 2-Port SATA II Expansion Card JMB362 Low Profile Bracket

SKU CH-WWE0-3TZ7S

Adds two SATA 2.0 ports at 3Gbps each using a JMB362 chip, includes a low-profile bracket for slim desktops, and supports SATA 1.0 drives

  • Adds two SATA 2.0 ports for extra drives
  • JMB362 chip delivers stable 3Gbps per port
  • Works with SATA 1.0 1.5Gbps legacy devices
  • Low-profile bracket fits slim SFF desktop cases
  • PCIe x1 design fits x1 x4 x8 x16 slots

Two SATA II ports for legacy drives

This SMUGDESK card adds two independent SATA II connections to a desktop using a single PCIe x1 slot. It targets owners of older systems who need extra ports for mechanical hard disks or optical drives. The JMB362 controller provides stable operation for everyday storage tasks.

Limited to 3 Gbps per port

Each port tops out at the SATA 2.0 rate of 3 Gbps, so modern SSDs cannot reach their full speed. The interface is backward compatible with SATA 1.0 devices running at 1.5 Gbps. Bandwidth is shared across the single PCIe lane, which caps total throughput for simultaneous transfers.

Low-profile bracket fits slim cases

A low-profile bracket is included for small-form-factor chassis, while the standard bracket works in full-size towers. The card installs in any PCIe x1, x4, x8 or x16 slot on mainstream Windows systems. Builders must verify that their motherboard BIOS recognises add-in SATA controllers before purchase.

Questions about this item

Should I choose the standard or low-profile bracket for my slim desktop?

The card ships with a low-profile bracket included, so it fits slim SFF and compact chassis without needing a separate bracket.

What does the 3 Gbps per port rating mean when I connect a modern SSD?

Each port delivers up to 3 Gbps SATA 2.0 bandwidth; a modern SSD will run at SATA 2.0 speeds rather than its native SATA 3.0 ceiling.

Does the PCIe x1 interface limit the two SATA ports in practice?

The single PCIe x1 lane supplies enough throughput for both ports at their 3 Gbps SATA 2.0 maximum, so the interface does not create a bottleneck.
