Lexar Professional 2000x & 1667x 128GB SDXC UHS-II Cards - Fast

In this review the focus is practical: photographers and videographers who need reliable, high-speed SD cards for DSLR and cinema-quality cameras will find clear benefits here. The two Lexar options tested offer UHS-II performance with a single biggest advantage being fast read speeds for quicker offloads and smoother post-production. Both cards are aimed at users who shoot extended Full-HD or 4K footage and want to minimize transfer time while preserving capture performance.

Key Features

• UHS-II Read Speed: Up to 300MB/s (2000x) or 250MB/s (1667x 2-pack) read speeds reduce transfer times and speed up workflow when copying files to a computer.
• High-quality Video Capture: Designed to capture extended lengths of Full-HD and cinema-quality 4K video without dropping frames when paired with compatible cameras.
• U3 Performance Class: UHS Speed Class 3 (U3) provides consistent write performance suitable for continuous burst shooting and high-bitrate video recording.
• Backwards Compatible: Both cards work in UHS-I devices so they remain usable in older cameras or cards readers at reduced speeds.
• Durable Design: Built to withstand typical field use and handling, offering confidence when shooting on location.

Who It's For

These Lexar UHS-II cards are best for professional and enthusiast photographers or videographers who regularly shoot high-resolution stills and long Full-HD or 4K video clips and want faster transfers to shorten editing time. They suit workflows where moving large files quickly from card to workstation is important.

Casual users who rarely shoot 4K or transfer large batches of files may not need UHS-II performance and could save by choosing lower-speed UHS-I cards. Also, users with cameras that do not accept UHS-II will not see the full speed advantage.

Pros & Cons

Pros

• Very fast read speeds that accelerate file transfers and post-production.
• Reliable for long Full-HD and cinema-quality 4K recording when used in compatible cameras.
• Backwards compatibility lets the cards be used in older UHS-I devices.
• Durable construction suitable for on-location shooting.

Cons

• Some customers report mixed reliability in specific camera models, so testing in your gear before critical shoots is advised.
• Write speed details are implied by U3 class but not specified, so peak write performance may vary by model and camera.

Specifications

Our Verdict
