This is a new all-time low price for this massive microSD card, and we’re not sure it’ll ever be this cheap again. In other words… HURRY!

What you need to know
Best answer: Adoptable storage is when you use a regular microSD card and have it act as if it were internal (non-removable) storage on your phone. It’s slower than the actual internal storage, can fail if used too much, and once you do it you can never remove the card again unless you reset your phone. That’s why many Android device manufacturers don’t enable the option.
