The Sony 1920GB CFexpress Type A TOUGH Memory Card are designed for professional photographers, videographers and enthusiasts looking to super-charge their workflow with unrivalled speed and reliability. Ultra-high speed performance 1 (up to 800MB/s read and 700MB/s write) is efficiently packed in the compact and durable body, to help you get the most from the latest high-end cameras. This quick performance benefits recording a variety of video resolutions, bit rates, and compressions, as well as high-resolution continuous raw photo shooting. Beyond its speed, this TOUGH memory card also has a reinforced physical design to withstand drops from up to 24.6' and has been rigidity tested to 150 N of force. It can perform in temperatures ranging from 14 to 158°F and is IP57 rated for dust and water resistance. Offering further protection, File Rescue recovery software can be downloaded for recovering lost or even accidentally deleted files and Media Scan Utility can be used to automatically scan CFexpress cards to inform you of the flash memory condition.
These new cards — the CEA-M Series — feature minimum sustained write speeds of 200 MB/s, but can withstand drops of up to 24.6' and are rigidity tested up to 150 N. While the CEA-G Series does feature minimum sustained write speeds of 400 MB/s, it can only withstand drops up to 15' and is rigidity tested up to 70 N. So, it comes down to whether you need more speed or more durability.
