Nextorage NX-F2AE

The Nextorage NX-F2AE series covers SDXC UHS-II cards built for video recording. It ships in 256 GB, 512 GB and 1 TB, so one family covers everything from a short job to long days with large files. In practice, that means choosing capacity by shoot length and keeping a spare card on set for long days.

The cards meet V90, the highest video speed class in SD, with a guaranteed minimum sustained write of 90 MB/s, and they claim read and write speeds up to 300 MB/s. They use TLC NAND memory, include a write-protect switch and target 4K, 8K and high frame rates without dropped takes.

The manufacturer puts the series through seven durability tests: operation from −25 °C to 85 °C, a 1.5 m drop, 10 N bending, 10,000 connector cycles, X-ray resistance to ISO 7816-1, magnetic protection and electrostatic discharge to IEC 61000-4-2. To use the full UHS-II bandwidth it recommends its NX-DF1CL dual-slot reader.

Reference prices are 299.99 dollars for 256 GB, 529.99 for 512 GB and 999.99 for 1 TB. The choice depends on take length and format: 8K benefits from the largest card, while interviews or documentary work in 4K often fits the middle sizes. Keeping a copy on an SSD before wiping the card remains the safe habit.
