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.
Review: ⭐⭐⭐⭐ Fast, Reliable, and High-Capacity - The SanDisk 256GB Extreme microSDXC performs very well, with fast read/write speeds that handle 4K and 5K video smoothly. The included adapter is handy, and the large 256GB capacity is great for cameras, drones, and other devices. My only drawback is that it’s a bit expensive compared to similar cards, but the quality and reliability make it worth considering. Overall, a high-performance and dependable microSD card, just slightly pricey.

## 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.

### ⭐⭐⭐⭐⭐ Good value for a quality micro memory card
*by L***E on December 27, 2025*

### ⭐⭐⭐⭐ ⭐⭐⭐⭐ Fast, Reliable, and High-Capacity

### ⭐⭐⭐⭐⭐ Works on the original Switch. Does not work on Switch 2. learned the hard way.
*by J***N on March 6, 2026*

Works great on my "Nintendo Switch", so I bought another one, thinking it would work on my Switch 2. Negative, it does not work on my Switch 2 at all. Thus, I now have 4 tb of storage for my switch 1. This honestly is not a bad situation to be in for me, since I have at least 2 tb of cloud games on my Switch that need a card to sit on. However, I can not respect the price for it, as it will be relegated to outdated tech. This has nothing to do with the card or the price of the card. Just being stuck using it for the Original Switch invalidates the value of the use case of this card for me.
