UGREEN USB 3.0 Dual Bay SATA Hard Drive Docking Station – CM198

The UGREEN CM198 provides versatile storage expansion and data management capabilities through its dual-bay design. This professional-grade docking station offers simultaneous access to two SATA drives while maintaining high-speed data transfer through USB 3.0 connectivity.

Advanced Dual-Drive Technology

The CM198 features independent drive slots that support concurrent operation of two SATA drives. Its intelligent design accommodates both 2.5″ and 3.5″ hard drives or SSDs without requiring additional adapters. Furthermore, the drives operate independently, allowing simultaneous access to both storage devices through a single USB connection.

UGREEN engineers the CM198 with an advanced chipset that supports UASP (USB Attached SCSI Protocol) for enhanced performance. This technology delivers up to 70% faster read speeds and 40% improved CPU utilization compared to traditional BOT (Bulk-Only Transport) protocol. As a result, users experience significantly improved file transfer rates and reduced waiting times during large data operations.

The dual-bay architecture supports multiple usage scenarios:

• Simultaneous access to two separate drives for data comparison or transfer
• Clone functionality for creating exact disk duplicates without a computer
• Support for drives up to 16TB each (32TB total capacity)
• Hot-swapping capability for replacing drives without system reboots

These technical elements combine to provide exceptional flexibility for data management professionals and enthusiasts alike.

Thoughtful Physical Design

The UGREEN CM198 features a vertical orientation that minimizes desk footprint while providing optimal airflow around installed drives. The open design promotes natural heat dissipation, while the integrated cooling fan ensures proper temperature regulation during intensive operations. Moreover, the sturdy base provides stable positioning even with two heavy 3.5″ drives installed.

The docking station incorporates user-friendly elements throughout its design:

• Individual power buttons for each drive bay
• LED indicators showing power and activity status
• Top-loading drive slots for easy insertion and removal
• One-button offline clone functionality for direct drive duplication

These practical features simplify daily operation while enhancing user experience. Additionally, the tool-free design eliminates complicated installation procedures, allowing quick drive swapping without specialized equipment.

Universal Compatibility Profile

The UGREEN CM198 delivers broad compatibility across multiple computing platforms. Its USB 3.0 interface connects to various systems including:

• Windows computers (7/8/10/11)
• macOS systems (10.6 and newer)
• Linux distributions with standard USB storage support

The CM198 supports all standard SATA drives including HDD, SSD, and hybrid variants across both 2.5″ and 3.5″ form factors. This versatility makes it an ideal solution for accessing multiple drive types without requiring separate adapters or enclosures.
