SanDisk Ultra 32GB UHS-I Class 10 Card with Adapter - $14.99
Compromising on transfer speeds may mean that your games take longer to load, but it also means that you can get more storage for less money. That’s the trade-off with external storage. The SanDisk Ultra 32GB UHS-I Class MicroSD Card starts at $9.90 for a 16GB model, but goes all the way to $34.99 for a model that has 64GB of storage.
It only offers 48MB/s reading speed, which is almost half of what the other SanDisk card in this breakdown offers. If your main concern is cost, go with this version. If you come to realize that it’s low speed is too big of a compromise, Amazon has a pretty straight forward return policy.
