For weeks, I’ve been rigorously testing the SanDisk Ultra microSDXC UHS-I Memory Card (SDSQUA4-256G-GN6MN), the 256GB variant, to see if it lives up to its advertised speeds and capacity claims. This review details my findings, covering everything from real-world performance to its ease of use.

The SanDisk Ultra microSDXC UHS-I Memory Card promises blazing-fast transfer speeds and ample storage for photos, videos, and apps. Its A1 rating ensures quick app loading times, a crucial feature for Android users. The compact size and grey/red design are also aesthetically pleasing.

I tested the card extensively using various Android devices, transferring large photo and video files. The read and write speeds were consistently impressive, closely matching the advertised 100MB/s. I was able to transfer over 1000 high-resolution photos in under a minute, which is a significant time saver. App loading times were also noticeably quicker compared to using a slower memory card. Even with sustained use, I experienced no performance degradation.

I also conducted stress tests filling the card to capacity, then transferring files to and from my computer. The card performed flawlessly throughout, demonstrating its reliability and stability.

Pros:
