Review: Small but mighty! - The SanDisk 1TB Extreme microSDXC UHS-I Memory Card with Adapter is a powerhouse of performance packed into an incredibly tiny form factor. I use it across multiple devices—my DJI Osmo Pocket 3, DJI Mini 3 drone, and even my older DSLR via the included adapter—and it performs flawlessly every single time. The read/write speeds are excellent, ensuring smooth 4K video recording and quick file transfers, which is essential for both professional and hobbyist creators. It’s impressive how such a small piece of tech can handle such large, high-resolution files without a hiccup. What really stands out is the card’s reliability and durability. Whether it’s been exposed to varying temperatures, inserted and removed countless times, or used across different camera systems, it has held up perfectly. SanDisk’s reputation for producing dependable storage devices is well-earned here. It’s also incredibly portable—you can carry a terabyte of data in something smaller than a fingernail, which still feels a bit like magic. I loved this memory card so much that I immediately bought a second one, and that’s honestly the highest praise I can give any tech product. It’s one of those purchases that just works, no fuss, no issues, and no second-guessing. If you’re serious about video recording, photography, or just need massive storage in a compact form, this is hands down one of the best investments you can make. A solid 5/5, great value for your money!
Review: Good value for a quality micro memory card - I bought this memory card for my Samsung tablet. It fits perfectly, and is recognized by the machine. As far as I can detect, it works perfectly. It was a very reasonable price for a quality chip. Because it is so small, the opening in the tablet was a little tricky to deal with, but installation was still easy. I would recommend this card for lots of extra memory.

## Questions & Answers

**Q: Is it class 10**
A: Yes. Actually, it is at least 3x more capable at U3 than Class 10. Class 10 is 10 MB per second. There is a new "U" series defined for video, that extends the old class system. U1 has the same rate as Class 10. U3 is 30 MB per second. The Extreme is a U3 card.

**Q: Can i record music on this card? it so, how many hours of music will it hold? thank you, brian**
A: Yes, you can record any digital files on this card. It is extremely fast, and can even handle 4K videos, and digital images. It's rated very fast. 
So, music away! The hours of recording have to do with the quality and size of the files. I would suggest that you record onto your PC/Laptop, etc. Then, transfer to this card. The card will handle recording directly, but you might like to do some editing in between. 
Here's a rough estimate of file size vs storage space:

**Q: can it be used for the nintendo switch?**
A: According to Nintendo, the Switch can accept microSD and microSDXC cards, and supports up to 2TB of total storage. This card is fast and should enhance your gaming experience.

**Q: How come this sd card written shipping fed is free but it still charge after i process the payment?**
A: $25.00 shipping though is super overkill in my opinion for a dang SD card. Prime member or not I would return it for having the audacity to charge that much for such a small/lightweight item.

### ⭐⭐⭐⭐⭐ Works with my insta360x5
*by I***O on February 19, 2026*

I ordered it primarily for my insta360x5. Worked right away, no slow card warning and no formatting needed. I'm quickly finding out i need more storage 😅. I think it was quite affordable, and good for any kind of shot the 360 throws at it including 8k. Can't wait to see how it reliable it will be for the next couple of months.
