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: https://qph.fs.quoracdn.net/main-qimg-689dff666b8e146d2e19bce49ddde53e **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. ## Frequently Bought Together - SanDisk 256GB Extreme microSDXC UHS-I Memory Card with Adapter - Up to 190MB/s, C10, U3, V30, 4K, 5K, A2, Micro SD Card - SDSQXAV-256G-GN6MA - uni SD Card Reader, High-Speed USB C to Micro SD Card Adapter USB 3.0 Dual Slots, Memory Card Reader for SD/Micro SD/SDHC/SDXC/MMC, Compatible with MacBook Pro/Air, Chromebook, Android Galaxy --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ro/products/452714468-256gb-extreme-microsdxc-uhs-i-memory-card-with-adapter-c10](https://www.desertcart.ro/products/452714468-256gb-extreme-microsdxc-uhs-i-memory-card-with-adapter-c10) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-10-19*
