Best SD and microSD Cards for Chromebooks 2022

Whether you bought a budget model or the best one on the market, you should get the best microSD card for your Chromebooks. Extra storage space for photos, video, documents, or anything else worth keeping is possible with a microSD card slot. If you're looking for affordable storage for your Chromebooks, these are the best choices.

microSD cards fit in a wide range of devices, from the best Chromebooks to cameras and more. If you can catch it during a sale, it's hard to go wrong with it. If you're looking for more storage than the most expensive Chromebooks can give you, the SanDisk Extreme can be a good choice. If you grab the best card you can right now, you will get an easy-to-use card that can be used in your next Chromebooks, too. You could always grab an external hard drive if you need it.

If you're rocking an older model, there may still be a full-sizeSD slot on it. If there is, I still recommend getting a microSD card because they are compatible with a wide range of devices. If the user is a young child that could lose a microSD card the size of their thumbnail, and if they have a full-sizeSD card like the Kingston Canvas Go! It's what the teacher ordered.

Demystifying SD classifications

In addition to the straight read and write speeds listed for the card, most of the cards have at least two of these classifications. These symbols mean something.

RECOMMENDED VIDEOS FOR YOU...

• Video Speed Class — Indicated by a stylized V followed by numbers from 6 to 90, this class is one of the newer classification systems and was developed specifically for shooting ultra-high-definition video. V30 starts at 30MB/s write speed, V60 starts at 60MB/s write speed, and V90 starts at 90MB/s. Your Chromebook won't be shooting 4K video, but it's a nice indicator of speed compared to UHS.
• UHS Speed Class — Indicated by a 1, 2, or 3 inside a U, this class is still used on most cards today. U1 starts at 10MB/s write speed, U3 starts at 30MB/s write speed, and either one should be okay for a Chromebook.
• Speed Class — Indicated by a number inside a C, this was the original classification system for SD cards. Class 10 (10MB/s write speed) was as high as this class went, so it's not as helpful an indicator of power/quality these days since almost every card is Class 10.
• Application Performance Class — Indicated by a stylized A followed by 1 or 2, this class is supposed to be a measure signifying that a card is optimized for storing and running Android apps. You won't need to worry about this one on a Chromebook as you cannot currently install apps to the SD card on a Chromebook.

The write speed is the focus of these specifications. If you see a card with a transfer speed of 100MB/s but only a U3 class, the chances are that it has a read speed of 100MB/s and a write speed of 30 MB/s.
