Best microSD Cards In 2021
Kids today don’t know how good they have it. Back in our day, if you wanted to store a whole summer’s worth of pictures and video – with room to spare for your favorite tunes – you’d need four cell phones, an MP3 player and a camcorder. Even then, that might not be enough. But enough drifting dangerously close to the Abe Simpson Old Man Yells at Cloud meme, let’s instead appreciate the marvels of device storage. We’ve had the pleasure of watch floppy disk evolve into CD, to flash drives, to SD cards and now the best microSD cards, which can hold days’ worth of information you may not look at again, but at least you know it’s there.
With us able to make new memories every day, we need these accessories to ensure we remember every single moment. Every hilarious quip, every embarrassing situation, and every bizarre occurrence that has to be recorded to be believed. Whether you take photos, videos, or stockpile tunes, a microSD card is essential, so enhance your life with one of these we’ve picked out just for you.
The Best microSD Card
A great inclusive option for the best microSD cards is this Samsung MicroSD EVO Select.

For versatile storage and transfer options, it also comes with a full-size SD Adapter, adding an extra level of data protection with its durable design and construction.

Ideal for Android smartphones and tablets, this SanDisk 64GB microSDXC is a next level storage device acting as much more than a mere memory card. On top of the fast read/write speeds, it comes with built-in data protection in the form of the RescuePRO Recovery Software. We all know how devastating it can be to lose all your data without warning, nor doing anything wrong – it’s devastating when you have done something wrong, but at least you can place the blame somewhere – so this offers peace of mind you may never have had with an SD card before.
Besides this, the SanDisk Memory Zone gives you easy file organization, which is great news for those who take more pictures than they can keep up with. To sweeten the deal, it supports 4K recording and comes with a lifetime warranty, so there’s (pretty much) no limit to what you can record and store.

It comes with top-class read and write speeds – 100MB/s and 90MB/s – as well as all the protections necessary to ensure long life and durability.

MicroSD Card Buying Guide
How We Chose Our Selection of microSD Cards
Brand - First, we look at the brand. You know a few of these on the list - mainly SanDisk, Samsung, and Kingston, but it doesn’t end there. Like any industry, there are always a few diamonds hiding in the rough, and we’ve found some of those which stand comfortably beside the big boy as they’ve always belonged.
Reviews - We believe the average review is a veritable goldmine of information covering the good, the bad, the unusual, and the essential insights we need to help us make our selection. For something as prominent as microSD cards we needed the very best of the best. If there were reports of corruption, it was out. If it transferred slowly, it was out. We have high standards with microSD cards, and if it didn’t make the cut, well that’s too bad.
Price - Just because they are small memory cards doesn’t mean you should avoid paying an acceptable price for them. Don’t listen when your dad says they’re just a bit of plastic, these little cards can hold your entire life on them. Unlike most lists where we try to avoid finding anything too expensive, this time we steered well clear of anything too cheap, as this could end in corrupt data and a lot of tears.
Some microSD cards are pricier than what you‘d like to pay but they come with a large enough capacity to justify it and we believe we’ve found a great range of sizes and prices for everyone.
Features To Look For In microSD Card
It’s not just about the price or of the microSD you need to consider. Here are the extra features that will help you decide which microSD card is the right one for you.
Storage Size - The more storage the better right? Well, kind of. While it’s true that large capacity microSD cards will maximize your storage options, such as have somewhere for movies, TV shows, music, and your own videos, this isn’t always viable.
There are devices which will only accept up to a certain size microSD. This includes smartphones, tablets, action cameras, and dash cams. Before purchasing your microSD card, double check with the device you’re intending to mount it in, otherwise, you could end up with poor or non-existent footage, and miss capturing those awesome moments.
Transfer Speed - Everyone hates waiting around for files to transfer. In fact, if we could measure how long we’ve waited in our lifetimes for files to copy from one device for another we’d probably have to take stock and reconsider our lives altogether. MicroSD cards operate at several speeds, ranging from at least 2MB/s to 150MB/s.
If you’re transferring small files like music and pictures, it may not be too much of a concern how quick the transfer is - aside from saving you time in doing things - however, for larger files like videos, faster transfer speeds means a more efficient day, and the quicker you can transfer 2 hours of 4K video to another device, the sooner you can get one with everything else you need to transfer.
Adapter Card Readers - Adapter card readers look exactly like the original SD cards of yore only now they have a small slot in the base for you to slide the microSD card into it. From here, it works exactly like the traditional SD card and gives you the ability to access files directly, even if you don’t have a microSD card reader built into your device.
Most modern laptops and PCs will have an adapter card slot, but if they don’t, then there’s little need for you to find a microSD kit with an adapter. You can always connect to your device via USB. The Adapter Card makes it easier to transport and store your microSD if you’re not using it, though, so this decision is completely up to you.
SDHC - The HC stands for high capacity and relates to any SD card which meets the new SD card 2.0 specification. Ranging from 4GB to 32GB, these are the typical SD cards you’ve used for the last few years. They look exactly like original microSD cards, but are more reliable, contain higher capacities, and quicker transfer speeds. Even if you haven’t upgraded your microSD in a while (until you finish reading this article that is), you likely have one in at least device at home.
But technology moves quickly, often much quicker than the average dude can keep up with, and so it’s likely you will need the next version up in microSD cards. This leads us to…
SDXC - Released in 2010 - wow, doesn’t that feel long ago? - the SDXC cards can store vast files such as HD and 4K video without the risks of corruption or frame skipping as you may encounter with less powerful cards. They begin at 64GB and can be as large as 2TB, all on something the same size as a fingernail which is super neat, no?
Micro SD Card FAQ
Q: What do the different classes of SD cards mean?
A: It’s not some awful, antiquated system that determines who can use which microSD card, but the class rating has helped standardize speed ratings for cards. These classes range from Class 2 to Class 10, graduating by two each time (so there’s no Class 1, Class 3, Class 5, etc.).
The Class Rating on your microSD shows the minimum write speeds, meaning at the very least you can transfer data at that specified speed.
- Class 2 2MB/s
- Class 4 4MB/s
- Class 6 6MB/s
- Class 8 8MB/s
- Class 10 10MB/s
Easy right? Remember, these are the minimum write speeds, so it’s possible your microSD card could achieve much more than this. Some cards boast write speeds up to 150MB/s, which is quicker than we can even think.
These are just basic speed classes though. SD cards of today are registered as UHS Class, which stands for Ultra High Speed. Divided into two classes - UHS Speed Class 1 and UHS Speed Class 3, they provide a minimum write speed of 10MB/s and 30MB/s.
Q: Can an SDHC reader read SDXC?
A: SDXC cards are backward compatible, so a reader that works with SDHC cards will also work with SDXC cards. However, this does not work the other way around, and you cannot use an SDXC reader with an SDHC card unless you have sufficient software to support this difference.
Q: Will microSD cards fit all phones?
A: It will fit all modern phones except those without expandable storage, such as the Google Pixel and any iPhone due to their large internal memory and dependence on cloud storage. But just because it will fit in all phones doesn’t mean your phone will recognize the card. Some cards have a limit on the amount of expandable storage, so (as we mentioned above) you should check it is compatible with your device before buying it.
