SanDisk 256 GB Extreme PRO CFexpress 4.0 Type B Memory Card

SanDisk, now operating under the Western Digital umbrella, has long been one of the most recognizable names in flash memory. Known for its broad range of SD, microSD, and CFexpress media, the company serves both consumer and professional markets across photography, videography, and data management. SanDisk’s strength lies in its large-scale manufacturing and quality control infrastructure, which allows it to deliver consistent performance across diverse product tiers—from entry-level SD cards to professional-grade V90 and CFexpress media designed for high-resolution recording. The SanDisk Professional line (formerly G-Technology) extends the company’s reach into the production and post-production workflow. This branch focuses on external storage solutions such as portable SSDs, RAID arrays, and high-speed card readers engineered for on-set data management. Designed with video professionals in mind, these products complement SanDisk’s recording media by supporting faster offload times, redundancy options, and sustained data transfer suitable for 4K, 6K, and 8K video environments.

Together, SanDisk and SanDisk Professional form an ecosystem that spans capture, transfer, and archival storage. The company’s adherence to industry standards such as VPG and V-Class ratings, along with its focus on long-term reliability and wide compatibility, has made it a staple choice across many camera systems. By combining mass-market accessibility with dedicated professional solutions, SanDisk continues to play a central role in the broader imaging and media production pipeline.
