PNY Elite 128GB Card
If you need a little more than 64GB but still want great performance, consider the PNY Elite. As you increase the storage limit the speeds typically drop a bit. Either way, games will still load fast and fluid.
A good middle ground is this 128GB card. Delivering nearly 150GB of space total, or more, without spending too much money.
There are dozens of 128GB cards to choose from. And while the SanDisk Ultra 128GB is pretty cheap, the PNY Elite delivers slightly better performance for just a few more dollars.
It's also extremely durable and can handle the drops and abuse of an Amazon Fire Kids tablet. PNY Elite microSD cards use a 4-Proof technology. Essentially they are temperature, water, shock (drop) and magnet proof. Meaning extreme hot or cold temps, vibrations from phone drops or drones and even magnets won't ruin one. They're built to last and come with a limited lifetime warranty.
