Exascend 1 TB UHS-I V30 SDXC Catalyst Memory Card

Exascend is a Taiwan-based storage manufacturer specializing in industrial and professional flash media, with a product range that has expanded into the cinema and broadcast market through a line of CFexpress and SD cards designed for sustained high-bitrate recording. The company's recording media includes CFexpress Type A and Type B cards in capacities ranging from 160GB through 2TB and larger, alongside SDXC UHS-II cards aimed at professional photography. The Nitro, Essential, and Archon product tiers target progressively more demanding cinema applications, with sustained write specifications calibrated for 8K RAW, ProRes, and other high-bitrate codecs used by Sony FX, Panasonic S, and Canon EOS cinema and mirrorless cameras.

Exascend's design philosophy reflects its industrial-grade roots: an emphasis on power-loss protection, wide operating-temperature ranges, and validated controller and NAND combinations selected for endurance rather than peak benchmark numbers. The company applies enterprise-derived testing methodology to consumer-facing professional media, with specifications focused on consistent worst-case performance across thermal and capacity-fill scenarios. This positioning targets owner-operators, documentary crews, and rental houses where card reliability under field conditions — rather than headline read speeds — is the primary purchase criterion. The brand competes alongside ProGrade Digital, Angelbird, and Nextorage in the professional media segment.
