I picked up the SanDisk Ultra 64GB microSDXC UHS-I card with Adapter – 100MB/s U1 A1 – SDSQUAR-064G-GN6MA as a microSD card solution for my drone and action camera setup, and I wanted to share what I found after putting it through actual use. At $11.49, this card hit my price point, and SanDisk has always been reliable in my experience. The specs looked solid on paper – 100MB/s read speed, UHS-I support, U1 and A1 ratings, plus the adapter included. I’ll give you my straight assessment of whether this thing delivers.
Why the SanDisk Ultra 64GB microSDXC UHS-I card with Adapter – 100MB/s U1 A1 – SDSQUAR-064G-GN6MA Stands Out
Out of the box, the SanDisk Ultra 64GB microSDXC UHS-I card with Adapter – 100MB/s U1 A1 – SDSQUAR-064G-GN6MA came packaged well with the SD adapter already included, which saved me from buying one separately. The card itself is tiny, as microSD cards are, but it felt solid. I tested it across different devices – my drone, my GoPro, and my laptop through the included adapter. The read speeds held up to their advertised 100MB/s in real-world testing when transferring 4K footage to my computer. Write speeds weren’t listed on the packaging, but they felt reasonable for my use case. The U1 rating means minimum 10MB/s write speed, which is plenty for most action cameras and drones. The A1 application performance rating showed in faster load times on my devices. I’ve documented these kinds of findings in detail on my recommended products page for others looking at storage solutions.
The card stayed cool during extended use, and I didn’t experience any stuttering or dropped frames while recording video. I tested the SanDisk Ultra 64GB microSDXC UHS-I card with Adapter – 100MB/s U1 A1 – SDSQUAR-064G-GN6MA in a drone that pushes sustained writes pretty hard, and it handled it without complaint. The 64GB capacity gave me enough space for several hours of 4K footage before needing to offload. SanDisk includes a limited lifetime warranty on these cards too, which shows the company stands behind the product. In my business, reliability matters more than saving a few dollars, and this card delivered on that front.
Would I Buy the SanDisk Ultra 64GB microSDXC UHS-I card with Adapter – 100MB/s U1 A1 – SDSQUAR-064G-GN6MA Again
Yes, I would buy this card again without hesitation. The SanDisk Ultra 64GB microSDXC UHS-I card with Adapter – 100MB/s U1 A1 – SDSQUAR-064G-GN6MA proved dependable across multiple devices and held up to demanding workloads. At the price I paid, the value proposition is strong. I’ve had SanDisk cards last years without issues, and I expect the same from this one. Some competitors offer slightly faster write speeds, but they cost more and don’t add meaningful benefit for my applications. The included adapter is convenient, the card is fast enough for 4K video, and the build quality is solid. If anything fails, the warranty backs it up. That’s a winning combination in my book.
For anyone shooting video, working with drones, or simply needing reliable expandable storage, the SanDisk Ultra 64GB microSDXC UHS-I card with Adapter – 100MB/s U1 A1 – SDSQUAR-064G-GN6MA deserves serious consideration. I’ve used it regularly for weeks now and have zero regrets. Pick this card if you need dependable storage that won’t let you down in the field.
