Pergear 256GB CFexpress 4.0 Type A Memory Card - Fast 8K & Burst

In this review the Pergear 256GB CFexpress 4.0 Type A Memory Card is evaluated for professional creators who need reliable, very high sustained speeds for RAW burst shooting and high-bitrate video. The bottom line: this card delivers exceptionally fast read and write performance - up to 1780MB/s read and 1600MB/s write - making it a strong choice for photographers and filmmakers using compatible Sony Alpha and FX bodies who want quicker offloads and uninterrupted 4K/8K capture.

Key Features

• High write speed: Up to 1600MB/s write enables long runs of high-bitrate 8K and continuous RAW burst sequences without dropping frames.
• Fast read speed: Up to 1780MB/s read dramatically shortens transfer times when offloading large video files or image libraries to a workstation.
• CFexpress 4.0 Type A standard: Fully compliant with the CFexpress Type A 4.0 specification for compatibility with modern cameras that accept Type A cards.
• USB4.0 interface: Next-generation interface support helps the card reach its top read speeds when used with an appropriate reader.
• Sony camera compatibility: Tested compatibility includes a range of Sony Alpha and FX models, making it a practical upgrade for users of those systems.
• Improved performance over earlier models: Designed to work up to 2x faster than prior Pergear CFexpress standard cards while retaining backward compatibility with Type A 2.0 devices.

Who It's For

The card is aimed at professional photographers and videographers who shoot high-bitrate 8K, 4K at high frame rates, or long RAW burst sequences and need fast offloads to keep workflow moving. Owners of compatible Sony Alpha and FX cameras who prioritize durability and speed will find the card particularly useful for demanding shoots and multi-day projects.

It is less appropriate for casual shooters or users whose cameras do not accept CFexpress Type A cards, and buyers should note that a CFexpress 4.0 Type A card reader is required to reach the published speeds and is sold separately. If you do not already have a compatible reader or camera, consider the additional cost before purchasing.
