I bought this card because I have several devices that use microSD cards, but not all of them are compatible with the newer and higher-capacity SDXC standard. For SDHC memory cards, 32GB is the largest size available under that technology standard, so I went with this one from Sandisk. That way I didn't have to worry about compatibility issues with any of my devices. I've used Sandisk memory products for a number of years along with many other brands, and I've always had good results from them. I'm happy to say that my experience with this card echoes that of 5,000+ other Amazon users; it's been rock steady, reliable with larger file transfers (several 2GB+ movies at a time), and performed as quickly as I'd hoped for a Class 10 card in regards to its read/write times.Aside from the existing reviews and my previous experiences with Sandisk products, I also picked up this particular card due to its UHS-1 compliance. I don't currently have any UHS-1 devices that can take advantage of the increased speed, but for the negligible cost difference, it just made sense. Standards and technology update so fast these days; any future-proofing a product can provide to extend its usable life is always appreciated.
