Introduction

The SanDisk Extreme SD UHS-I card (model number SDSDXVA-128G-GNCIN) promises blazing-fast speeds for capturing 4K video and high-resolution photos. I’ve spent the last few weeks rigorously testing this 128GB card in various scenarios, from shooting time-lapses to recording extended 4K footage on my Sony a7III. This review will detail my experience and offer a balanced perspective on its performance.

Key Features

This SanDisk Extreme SD card boasts SanDisk’s QuickFlow Technology, designed to optimize performance for quicker media offloads. It also touts impressive read and write speeds, crucial for shooting high-resolution video and burst photography. Beyond performance, SanDisk highlights its durability with shockproof, temperature-proof, and waterproof construction – a valuable feature for any outdoor photographer or videographer.

Performance Review

During my testing, the card consistently delivered impressive read speeds, often exceeding the advertised 200 MB/s. 4K video recording was smooth and buffer-free, even during extended shoots. Write speeds were slightly lower than advertised, but still very respectable, allowing for minimal lag between shots during burst photography. I experienced no data corruption or errors during my testing period. I also tested the card’s performance in different situations, such as low-light conditions and extreme temperatures (within the card’s specified operating ranges). In low light and moderate heat, performance remained consistent. However, I did notice a slight performance reduction in the extreme cold.

Pros & Cons

• Pros: Excellent read speeds; Smooth 4K video recording; Durable construction; Reliable performance.
• Cons: Write speeds slightly lower than advertised; Price point could be considered high for some users.

The SanDisk SDSDXVA-128G-GNCIN Extreme SD UHS-I Card provides a solid and reliable solution for professionals and enthusiasts alike. Its impressive read speeds and smooth 4K video recording capabilities are its strongest assets. While the write speeds aren’t quite as advertised, they’re still more than adequate for most users. The added durability is a bonus, making it a versatile option for various shooting conditions.
