The SanDisk 128GB Ultra microSDXC UHS-I Memory Card is the single best-selling memory card on Amazon’s entire site, and it’s pretty easy to see why. It supports data transfer speeds up to 100MB/s, which is what you’ll find on expensive “upgraded” microSD cards from other brands. Meanwhile, the same card from SanDisk is on sale right now for just $18.85 in this early Prime Day deal on Amazon. 200GB cards are also on sale for $30, which is a great price as well. What are you waiting for!?
