UGREEN USB 3.0 All-in-One Card Reader 50cm

UGREEN USB 3.0 All-in-One Card Reader 50cm

The UGREEN USB 3.0 all-in-one card reader (model CR125, SKU 30333) is a compact four-slot memory card reader that reads SD, Micro SD (TF), CompactFlash (CF), and Memory Stick (MS) cards simultaneously over a single USB 3.0 connection. It suits photographers, videographers, drone operators, and content creators who work with multiple card formats and need fast, reliable transfers without swapping cards in and out of a single-slot reader. A built-in 50cm cable with a multi-shield tin-plated copper core keeps the reader positioned comfortably on a desk without straining the host port.

Four Slots, Four Cards, One Connection

Single-slot card readers force a sequential workflow: transfer one card, eject, insert the next, repeat. For a photographer returning from a shoot with cards from multiple cameras — a DSLR on SD, a drone on Micro SD, and a mirrorless camera on CompactFlash — that sequential process adds unnecessary time and handling risk. The CR125 mounts all four cards as separate drives simultaneously on the host computer, allowing parallel transfers, drag-and-drop across cards, or direct card-to-card copies through the host file system. Furthermore, the 50cm cable positions the reader on a desk surface rather than hanging off a laptop USB port, reducing mechanical stress on both the connector and the host port over time.

The reader connects to any USB 3.0 or USB 2.0 Type-A port without driver installation on Windows 8 and later, macOS, and Linux. However, Windows XP and Vista require manual driver installation. Each card slot operates independently — inserting cards in any combination works without configuration, and removing one card while another is still in use does not interrupt the other transfer sessions.

Use Cases & Applications

Photography and Videography Workflow Ingestion

Professional and enthusiast photographers returning from a shoot frequently carry two or more cards from different cameras. A mirrorless camera typically uses SD or SDXC, a compact action camera uses Micro SD, and older or professional DSLRs may use CompactFlash. The CR125 accepts all three simultaneously, mounting each as a separate volume in Lightroom, Capture One, or Finder/Explorer for parallel import. Consequently, total ingestion time reflects the slowest single card rather than the sum of all card transfer times.

Drone and Action Camera Offload

Drone operators using DJI, Autel, or similar platforms commonly use Micro SD cards at capacities from 64GB to 512GB. Transferring 4K footage from a 256GB card at USB 2.0 speeds (≈25MB/s) can take over 10 minutes; at the CR125’s ≈90MB/s USB 3.0 throughput, the same card clears in under three minutes. Additionally, a secondary SD card from a ground-level camera can transfer in parallel, completing a full post-flight offload in a single operation.

Sony Device Users: Memory Stick Support

Memory Stick formats — including MS PRO and MS PRO-HG — remain in active use in Sony cameras, camcorders, and older PlayStation Portable devices. These formats are absent from the majority of modern card readers, which focus exclusively on SD and Micro SD. The CR125’s dedicated MS slot provides a practical solution for users who need to access this media without sourcing a single-format Memory Stick reader.

IT and Field Technicians: Multi-Platform Media Access

Field technicians working with surveillance cameras, industrial equipment, POS terminals, and embedded systems regularly encounter a range of memory card formats across different devices. Carrying a single CR125 instead of multiple format-specific readers reduces kit weight and eliminates the uncertainty of which reader to bring for which device. The plug-and-play operation across Windows, macOS, and Linux means it functions without driver installation in managed enterprise environments.
