UGREEN CM302 M.2 PCIe 3.0X4 Express Card

Product Description

UGREEN CM302 (70504) M.2 PCIe 3.0X4 Express Card

Laggy boot times and capped SSD performance hurt productivity and gaming flow.

The UGREEN CM302 (70504) M.2 PCIe 3.0X4 Express Card targets that bottleneck directly.

It brings modern PCIe bandwidth to desktops that demand faster data paths.

Designed by Ugreen, this SSD Expansion Card fits advanced builds.

It serves gamers, creators, and industrial systems needing stable throughput.

The focus stays on speed, compatibility, and long-term operation.

UGREEN CM302 (70504) PCIe Expansion Card Overview

It works as a dual-slot M.2 SSD transfer solution.

Both slots can operate at the same time.

The card supports PCI-E 3.0 X4 with up to 32 Gbps transfer rate.

That bandwidth suits NVMe workloads and large file movement.

Users gain better lane utilization through direct PCIe routing.

This model carries Part No: 70504 and a clean black finish.

The physical layout fits performance-focused desktop systems.

It targets builders who want speed without platform replacement.

Technical Specifications and Interface Capabilities

This Ugreen CM302 expansion card uses a PCI-E interface.

Input includes M.2 M-Key and M.2 B-Key connections.

Output supports PCI-E 3.0X4 and 7-pin SATA.

Supported M.2 SSD sizes include:

• 2230
• 2242
• 2260
• 2280

This wide size range supports compact and full-length SSDs.

The form factor stays flexible across system designs.

The card supports Windows and Linux systems.

BIOS PCIe settings must stay enabled for detection.

This requirement matters during first-time installation.

UGREEN CM302 (70504) Dual-Slot M.2 Design Advantages

The standout feature remains the dual M.2 slot layout.

Both slots work simultaneously without shared lane conflict.

That helps users scale storage without adding another card.

This design suits:

• High-end gaming mainframes
• Industrial computers
• Ultra-minimalist desktop builds

The expansion card supports storage growth while keeping airflow manageable.

Builders avoid clutter from multiple adapters.

Gold-plated contacts add stability during long operation cycles.

The plating thickness ranges between 0–5 mm.

This resists oxidation and signal degradation over time.

Performance and Data Transfer Stability

The 32 Gbps transfer rate supports PCIe 3.0 workloads effectively.

Large game assets load faster.

Media projects move quicker between drives.

The card focuses on steady operation under extended use.

Power delivery stays optimized for continuous workloads.

Thermal handling supports long sessions without interruption.

This makes the card suitable for systems running heavy I/O tasks.

Industrial environments benefit from predictable behavior.

Gaming systems gain smoother asset streaming.

Build Quality, Cooling, and Physical Design

The UGREEN CM302 comes in a black finish.

Dimensions measure 120 x 116.7 x 67mm.

This size suits standard desktop PCIe slots.

The card does not claim shockproof or waterproof traits.

Its strength comes from electrical stability and contact quality.

That focus suits controlled desktop environments.

Cooling optimization supports extended uptime.

The layout promotes heat dissipation from installed SSDs.

This helps maintain stable speeds during heavy access.

Compatibility and Supported Use Cases

The expansion card supports PCIe-based desktop motherboards.

It works best in systems with available PCIe slots.

BIOS PCIe configuration must stay active.

Ideal use cases include:

• Gaming PCs needing faster load times
• Workstations handling large datasets
• Industrial machines requiring stable storage throughput

Ultra-minimalist builds benefit from reduced cable complexity.

The dual-slot design saves motherboard real estate.

This product does not list maximum supported capacity.

Users should follow SSD and motherboard limits.

That keeps compatibility predictable.

Brand Trust and Warranty Coverage

Ugreen maintains a strong reputation in PC accessories.

The CM302 reflects that focus on electrical reliability.

Manufacturing takes place in China.

The product includes a 1-year warranty.

That coverage supports buyer confidence.

Warranty terms apply through authorized sellers.

For Bangladesh buyers, trusted sourcing matters.

Local availability supports after-sales peace of mind.
