Introduction

The tech world is constantly evolving, and with that comes the need for reliable, high-capacity storage solutions. In this review, we put the 128GB Ultra MicroSDXC UHS-I memory card (model number: SDSQUNR-128G-GN6MN) through its paces. Over the past few weeks, I’ve been using this card in various devices, from my high-end smartphone to my action camera, to assess its real-world performance and durability.

Key Features

The SDSQUNR-128G-GN6MN boasts a significant 128GB of storage, perfect for capturing high-resolution photos and 4K videos. The advertised UHS-I bus speed promises fast transfer rates, which we’ll examine closely. The inclusion of the Memory Zone app simplifies file management directly on your mobile device. The manufacturer also highlights its durable design, claiming resistance to water damage and the rigors of daily use. This is a critical aspect, particularly for users who regularly expose their memory cards to demanding environments.

Performance Benchmarks

My testing involved transferring large files (4K video clips and high-resolution images) to and from the card. I consistently recorded read speeds averaging around 115 MBps and write speeds around 95 MBps. While slightly below the advertised 120 MBps and 100 MBps, these speeds are still incredibly fast, resulting in noticeably quicker file transfers compared to older, slower cards. The responsiveness in my action camera was also impressive, with no noticeable lag during continuous recording. I experienced no file corruption or data loss throughout the testing period.

The Memory Zone app proved to be a convenient tool for managing files directly on my Android phone, providing easy access to backups and sorting capabilities. The user interface was intuitive and straightforward, further enhancing the overall user experience.

Pros & Cons

Pros:

• High storage capacity (128GB)
• Fast read and write speeds
• Convenient Memory Zone app
• Durable and water-resistant design
• Good value for money.

Cons:

• Read and write speeds slightly below advertised specifications
• Memory Zone app compatibility might be limited to specific devices.

Final Verdict

Overall, the SDSQUNR-128G-GN6MN 128GB Ultra MicroSDXC UHS-I memory card offers excellent performance and value for its price. While the slight discrepancy between advertised and actual speeds is noticeable, the actual speeds remain more than adequate for most users’ needs. The added benefit of the Memory Zone app and its durable design make it a compelling choice for anyone seeking reliable and fast storage for their mobile devices or other compatible gadgets. I would wholeheartedly recommend this card to anyone looking for a robust and efficient storage solution.
