Introduction
The SanDisk Extreme microSDXC UHS-I Card (SDSQXA1-128G-GN6MN) promises blazing-fast speeds for capturing and transferring high-resolution photos and 4K videos. But does it deliver on its bold claims? After weeks of rigorous testing, shooting 4K footage, and transferring gigabytes of data, I’m ready to share my comprehensive review of this 128GB memory card.
Key Features
This microSD card boasts impressive specs, including read speeds up to 160MB/s and write speeds up to 90MB/s. This translates to quicker app loading times, smoother 4K video recording, and significantly faster file transfers compared to standard microSD cards.

Performance Testing
I tested the SanDisk Extreme 128GB card extensively using a range of devices, including a high-end smartphone capable of 4K video recording at 60fps and a professional-grade DSLR camera. In my tests, the read and write speeds were impressive, though not quite reaching the advertised 160MB/s read and 90MB/s write speeds consistently. Real-world performance varied slightly depending on the device and the type of file being transferred. However, even with the minor discrepancies, the speed improvements were significant compared to my previous microSD card. I experienced no lag or buffering while recording 4K video and transferring large RAW image files. The A2 rating also proved its worth, providing snappy app performance and quick loading times.
I also subjected the card to a series of stress tests including continuous 4K video recording for over an hour, numerous rapid file transfers, and even accidentally dropping it (oops!). It emerged unscathed, reassuring me of its robust construction and durability claims.
Pros & Cons
- Blazing-fast read and write speeds
- Excellent 4K video recording performance
- Durable and rugged design
- Reliable performance under pressure
- A2 rating for enhanced app performance
Pros:
- Read and write speeds were slightly below advertised speeds in some tests.
- Price point is higher than some competing microSD cards
Cons:
Final Verdict
The SanDisk Extreme microSDXC UHS-I Card (SDSQXA1-128G-GN6MN) is a top-tier memory card that excels in speed, durability, and overall performance. While the advertised speeds weren’t always perfectly replicated in every scenario, the real-world improvements were undeniable. If you’re a serious photographer or videographer who needs a reliable and high-performance memory card that can withstand tough conditions, this card is a strong contender. Despite its slightly higher price, the improved speed and enhanced durability make it a worthwhile investment for professional-level applications and demanding users. I highly recommend it.
