Wise Advanced 128GB SD-N UHS-II SDXC Memory Card

The Wise Advanced 128GB SD-N UHS-II SDXC Memory Card (Model: SD-N128) is a broadcast-grade media card engineered for high-performance cinema cameras, continuous RAW burst photography, and high-bitrate 4K or 8K video capture.

As part of Wise's flagship SD-N (V90) lineup, this card is built using premium pSLC (Pseudo Single-Level Cell) NAND Flash memory. While standard consumer memory cards utilize lower-tier multi-level cells that cause write speeds to fluctuate and dip as the card fills up, pSLC architecture mirrors enterprise storage. It treats the memory cells as high-speed single-bit caches, delivering completely flat-line, rock-solid write performance and an incredibly high lifecycle write-endurance rating.

Core Speed and Class Classifications

• V90 Video Speed Class: This is the critical certification for high-end cinema capture. While burst speeds look impressive on the packaging, video tracking demands sustained continuity. The V90 label legally guarantees that the card's continuous write speed will never drop below a hard baseline of 90 MB/s, completely preventing dropped frames or sudden buffer crashes mid-take.

• Dual-Row UHS-II Interface: If you flip the card over, you will notice a second row of copper pins. This dual-row design handles high-bandwidth bus data routing. While it is fully backward-compatible with older, single-row UHS-I camera slots, inserting it into a UHS-I device will throttle the data bus to standard legacy bottlenecks ($\approx 10\text{ MB/s}$ to $30\text{ MB/s}$ limits).

Technical Specifications Matrix

Rugged Field Construction

Wise builds the SD-N series to withstand harsh, remote environmental conditions. The specialized composite housing features internal structural seals rendering the memory block:

1. Waterproof and Dustproof: Protected against high-moisture environments, rain, and fine particulate ingress.

2. Shockproof and Stress-Resistant: Capable of surviving physical drops, heavy camera-case vibration, and physical bending forces.

3. Airport X-Ray Proof: Impervious to the magnetic and radiation scanning arrays found inside airport security checks, protecting your master footage from accidental corruption during transit.

Native Camera Targets

The 128GB capacity tier is perfect for daily video production, balancing solid shooting times with safe data-redundancy practices (e.g., breaking a shoot across multiple cards rather than risking all your data on a single massive card). It is a standard choice for platforms like 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 uncompressed raw log stills.
