Review: Works with my insta360x5 - 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.
Review: Good card. - Stores more stuff than my brain. Worked as advertised.

## 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.
