Lexar 512GB Professional Silver SE CFexpress Type B - Fast 8K Card

Our review finds the Lexar 512GB Professional Silver SE CFexpress Type B card is aimed squarely at serious photographers and videographers who need high sustained speeds for large RAW files and multistream 8K video. The single biggest reason to buy is its class-leading sustained write performance, which lets cameras record long 8K takes without dropping frames or forcing frequent card swaps. In this review the card proved consistent in file transfers and offered ample capacity for full-day shoots while remaining compatible with select XQD cameras for users transitioning to CFexpress.

Key Features

• High read speed: Up to 1700MB/s read speed reduces transfer times and speeds ingest to editing workstations.
• Fast write performance: Up to 1250MB/s write speed allows rapid buffer clearing when shooting bursts of high-resolution images.
• Sustained writes: Sustained write rates up to 1150MB/s support long continuous 8K video recording without dropped frames.
• Large capacity: 512GB gives plenty of storage for extended photo and video sessions, cutting the need to swap cards mid-shoot.
• Backward compatibility: Works with select XQD cameras, helping users preserve investment in older camera bodies.
• Warranty protection: Limited 10-year warranty offers long-term peace of mind for professionals.

Who It's For

The Lexar 512GB CFexpress Type B card is best for professional photographers and videographers shooting high-resolution stills and 8K or high-bitrate 4K video who need fast sustained write performance and large onboard storage. If you routinely capture extended video takes, high-frame-rate bursts, or large RAW sequences, this card reduces downtime and speeds workflow.

Those with older cameras that are not CFexpress or who only shoot occasional JPEG stills at low resolution may not need this level of performance and could opt for a lower-cost card. Also check camera compatibility first, as full speeds require compatible camera bodies and readers.
