Professional video storage: CFexpress and SSD performance reviews

Testing results for high-performance storage media used in professional video production highlight the importance of sustained write speeds over peak benchmark numbers. For 4K RAW video recording, CFexpress Type B cards must maintain consistent data rates to prevent dropped frames and buffer overflows during continuous takes.

Evaluations of CFexpress cards across cameras such as the Nikon Z8, Canon R5, and Sony FX3 emphasize heat management and capacity. Similarly, portable SSDs used for direct-to-drive recording workflows are being assessed for their ability to handle heavy ProRes and RAW loads without choking. Key performers in these categories include models from SanDisk, Samsung, and Lexar, which are tested for compatibility and reliability in real-world filmmaking environments.
