Wise Advanced 512GB SD-N UHS-II SDXC Memory Card

The Wise Advanced 512GB SD-N UHS-II SDXC Memory Card (Model: SD-N512) is an enterprise-tier, ultra-high-capacity removable storage drive engineered explicitly for cinema payloads, high-frame-rate mirrorless setups, and 8K workflows.

What sets the SD-N (V90) series apart from cheaper standard SD cards (like Wise’s SD-S V60 series) is the integration of premium pSLC (Pseudo Single-Level Cell) NAND Flash memory. This underlying architecture provides dramatically faster, highly consistent sustained continuous data writes, which eliminates the frame-dropping and buffer stalling typical of lower-grade multi-level cell media under intense read/write stress.

Key Read, Write, and Bus Performance

• V90 Video Speed Class Guarantee: While maximum burst numbers can look impressive on paper, video capture relies on continuous performance. The standard V90 label guarantees that this card's internal write speed will never dip below a baseline of 90 MB/s under any thermal or storage-capacity load. This makes it fully compliant for uncompressed RAW burst shooting and high-bitrate codecs.

• UHS-II Pin Configuration: The card utilizes a dual-row pin structure on its back to handle high-bandwidth data routing. While it is fully backward-compatible with legacy UHS-I cameras, inserting it into a UHS-I slot will restrict its processing interface, dropping performance down to standard UHS-I or Class 10 limits ($\approx 10\text{ MB/s}$ to $30\text{ MB/s}$ minimums).

Technical Specifications Matrix

Ruggedization & Industrial Structural Integrity

Wise builds these cards to survive harsh, remote environment field tracking. The composite physical housing features built-in protective barriers rendering the storage cell:

1. Waterproof and Dustproof: Sealed against environmental moisture and fine particulate ingress.

2. Shockproof and Stress-Resistant: Capable of withstanding drops, heavy luggage vibrations, and physical twisting forces.

3. Airport X-Ray Proof: Immune to the magnetic and radiation scanning fields found inside security conveyor paths, ensuring recorded video masters aren't corrupted mid-transit.

Native Target Workflows

This massive 512GB tier is ideal for cameras that pull high data volumes but choose to retain the universal footprint of an SD slot over newer CFexpress cards. It is an industry staple for long continuous takes on platforms such as the Canon EOS C70, Panasonic Lumix GH7/S5IIX, Blackmagic Pocket Cinema Camera 4K, and Sony FX3/FX30 when capturing high-frame-rate All-Intra 4K profiles or raw log stills.
