5-Star Review for SanDisk microSD Card This SanDisk microSD card is fantastic! The storage capacity is exactly as advertised, and the read/write speeds are impressively fast, making file transfers and app performance seamless. It works perfectly with my phone, camera, and tablet, offering reliable performance across devices. I’ve used it for storing high-resolution photos, 4K videos, and apps without any issues. The build quality feels durable, and it even comes with a handy adapter. Overall, a reliable and high-performing microSD card—highly recommend it for anyone needing extra storage!

This has been the only brand of sdxc high speed cards I've used for a while now. I have one in my Nintendo switch OLED among many other things. I recently bought a Steam Deck OLED, and only got the 512gb version which I regretted almost immediately. I bought 512gb and a 1TB high speed sdxc cards. They work perfectly. I had a friend who was using the Amazon basics card in hers and was wondering why it was taking an hour just to format and another hour to transfer game data. I recommend this card and it fixed everything. If you have higher end tech you NEED a higher speed write/read card. This one fits all my needs perfectly. Well worth the money spent. They're reliable, always work, and work WELL. don't bother saving a few bucks with lower end cards. It's not worth the aggravation.
