Best memory cards for Amazon Fire Tablet 2022

Thanks to the included microSD card slot, you can grab one of the best memory cards for the Amazon Fire Tablet quickly to expand the storage. Whether you picked up one of the best Amazon Fire Tablets for yourself or your kids, you've probably noticed that the internal storage doesn't go very far. Unfortunately, you can quickly fill it up with some games, a few apps, and media, which is a bit of a letdown. So make sure to pair one of the best Android tablets with the best memory cards and bump up the storage.

Don't run out of storage: get these microSD cards for your Fire Tablet

Expand the storage with the best memory cards for your Amazon Fire Tablet

Even the best Amazon Fire Tablets don't come with a lot of internal storage, so if you're looking to increase available storage, any of the above cards will be more than adequate. Still, if we're recommending one out of them all, our top pick goes to the SanDisk Ultra 64GB MicroSD Card. 64GB is a lot of extra space for loading up your local files, and when you add that together with incredible transfers and a solid price, you have an enticing package.

Then again, if you know you have a lot of movies and games to store, you might need something more substantial. In that case, we'd recommend splurging for the SanDisk Ultra 200GB MicroSD Card. If you need even more storage, then there are good microSD card options that offer 512GB or even 1TB of storage in the list above. 

The SanDisk Ultra 200GB MicroSD Card offers a lot more space without breaking the bank. To add to that, the 120MB read speeds combined with the A1 Performance class makes it one of the best Fire Tablet memory cards that you can spend your hard-earned cash on. So, whether you are using Fire 7 for watching movies or a Fire HD 10 for getting your work done, it's a great microSD card to handle everything you need.

What those figures and numbers on microSD cards mean

You might have noticed a lot of proclaimed read/write speeds, something called an 'A Performance' class, the alphabet 'V' accompanied by a numerical figure, and a mysterious 'U' with a number inside on many microSD cards. Here's what all those little letters and numbers really mean. Understanding these abbreviations will greatly help you understand storage card specifications and how relevant they are when purchasing a microSD card for your Amazon Fire tablet or Android phone with expandable storage.

  • A1 / A2 / A3: The A Performance class basically indicates the level of performance a microSD card will deliver when running applications off of it. If your microSD card lacks A1, A2, or A3, it won't be able to store and run apps. The fastest class is A3, followed by A2 which is slower, and then A1 which is the slowest rank.
  • V30 / V60 / V90: 'V' indicates the Video Speed Class of a microSD storage card. So, V30 translates into a 30MB per second write speed for Ultra HD video files. In line with that, V60 stands for 60MB/s and V90 for 90MB/s high definition video writing speeds.
  • U1 / U2 / U3: A microSD card's UHS Speed Class can be understood by looking at the 'U' printed on the card along with the number next to it. U3 is the fastest, delivering 30MB/s write speeds. Then you've got the slower U2 20MB/s and U1 10MB/s write speeds.
  • C10: Ever seen a little '10' encircled in the third letter of the English alphabet? That's the C10 logo which was previously used to depict the write speed of an SD card. It is equivalent to the U1 class of the UHS Speed Class. A C10 microSD card has a humble 10MB/s write speed.
  • microSDXC / microSDHC: You may notice that many microSD cards mention whether they fall under the microSDXC or microSDHC category. Don't feel afraid as these names are actually pretty simple to understand. Basically, a microSDHC card has between 2GB and 32GB of storage space. Meanwhile, a microSDXC card has a storage capacity of 32GB or higher, going all the way up to 2TB.

For your typical Android tablet like the Fire HD 10 Plus or the Fire HD 8, you don't require lightning fast read/write speeds. If you plan on installing and running apps off your microSD card, make sure it has at least an A1 rating. Extremely high Video Speed Class standards are unnecessary for streaming Netflix and playing Candy Crush. Grab something with a V30 class, because you don't really need anything faster.

Lastly, a UHS Speed Class ranking of U1 is sufficient for your Fire tablet. I reiterate, running a cheap Android tablet doesn't require super quick microSD card write speeds. If you don't spot the U1 mark on your card, it'll surely be replaced by the C10 logo instead. Remember, both alphanumerical symbols represent the same 10MB/s write speed, so there's absolutely nothing to fret over.
