This article covers Lexarプロフェッショナル1800x microSDXC 128GB UHS-II W.

Overview

The Lexar Professional 1800x microSDXC 128GB UHS-II Card & USB 3.0 Reader bundle is a practical storage solution for creators and mobile users who demand high transfer speeds. The kit includes a 128GB microSD card rated at 270MB/s read speed and a dedicated USB 3.0 reader, ensuring you can immediately take advantage of the card's UHS-II performance without needing to buy a separate reader.
This card meets UHS Speed Class 3 (U3) requirements, making it suitable for continuous 4K video recording and burst photography. The bundled reader connects via USB 3.0, allowing the card to reach its full potential when transferring large files to a computer.

Connectivity & Compatibility

  • Interface: USB 3.0 (backward compatible with USB 2.0/1.1)
  • Supported cards: microSDXC, microSDHC, UHS-II and UHS-I cards
  • Compatible devices: Windows PCs, Macs, Chromebooks, and any device with a USB-A port
  • Card speed class: UHS Speed Class 3 (U3), Video Speed Class V30 (estimated)
    The reader is designed to handle the card's 270MB/s read speed through USB 3.0's 5Gbps bandwidth. For best performance, connect to a USB 3.0 or higher port; using USB 2.0 will significantly reduce transfer speeds.

Best Use Cases

  • Drone and action camera users: The card's U3 rating ensures stable write speeds for 4K video, and the reader enables fast offload to your PC after a long shoot.
  • Smartphone/tablet storage expansion: If your device supports UHS-II microSD, this card can accelerate app loading and file transfers. The included reader makes it easy to move data between your phone and computer.
  • Photographers and videographers: When working with large RAW files or 4K footage, fast transfer speeds save time. This bundle is optimized to work together, so you won't face bottlenecks from a slow reader.
    Not ideal for users who only have UHS-I devices or require SD card format; in those cases, a standard SD card and separate reader may be more cost-effective.
