SanDisk’s made-for-Android 200GB microSD card is a ridiculously low $55.99 today in an Amazon Gold Box deal. This is the A1 card that has been rated for application use.
In fact, the description specifically notes that this is built for Android devices, features transfer speeds up to 100MB/s, is UHS Speed Class U1 and Speed Class 10, and also has enough storage to last you through numerous phones.
If you own a device with a microSD slot and have not pulled the trigger on a card, now is the time.
