The SanDisk Ultra is a pretty fast micro SD card, with speeds of around 100MB/s which is pretty good, and great for recording 4K video and such. This is the 400GB model, which is the highest capacity micro SD card that SanDisk currently has in its portfolio. Making it a great micro SD card to pick up and use. It is also an A1-rated card, which makes it great for storing apps and games on the micro SD card, without experiencing any lag with your smartphone. With 400GB capacity, you'll have around 390GB of usable storage out of the box, which is still plenty for most people, which is a good thing. Especially if you take a lot of photos or even keep a lot of music offline on your smartphone to listen to at any time. This micro SD card from SanDisk does also come with an adapter, so you are able to use this micro SD card in a device that uses a regular sized SD card, like a DSLR. Makes it great for using it in multiple devices, making this SD card even more impressive at this price tag.
