SUNEAST SE-CFXB640S1700 Ultimate Pro 640GB CFexpress Type B Memory Card

SUNEAST SE-SDU2064GA300 64GB V90 SDXC UHS-II Memory Card

A 64GB SDXC card built for professional capture, supporting 8K/4K video and high-speed stills. It operates in UHS-II mode for maximum throughput and is backward-compatible with UHS-I devices. Designed for frequent rewrite use with pSLC, it includes robust temperature and drop test ratings.

Key performance figures include up to 300MB/s read and 290MB/s write in UHS-II (HD312) mode, and up to 95MB/s read and 90MB/s write in UHS-I (SDR104) mode. It meets V90/U3/C10 speed classes and integrates CPRM/ECC, static & dynamic wear-leveling, and RoHS/CE/FCC/VCCI compliance.

Key Features

• High-Speed Performance: Up to 300MB/s read and 290MB/s write in UHS-II (HD312) mode; up to 95MB/s read and 90MB/s write in UHS-I (SDR104).
• Video Speed Class V90: Supports sustained video capture requirements (V90/U3/C10) for 8K/4K recording.
• pSLC NAND: Optimized for frequent rewrites and reliability.
• Backwards Compatibility: Works in UHS-I devices with SDR104 speeds.
