From smartphones and tablets to action cameras, dashcams and drones, microSD cards are everywhere, and are a vital part of the data capturing and storage for consumers and professionals alike.
And let me tell you what else is everywhere — poor quality and even counterfeit storage cards. The good news is that even the very best microSD cards that money can buy aren’t going to break the bank, and for the sake of your data, it’s well worth spending the money on genuine cards. Over the years, I’ve gone hands on with many microSD options on this list and beyond, considering features like capacity, price, and performance.
Also: What do all those microSD and SD card numbers and letters mean?
Based on my testing, my pick for the best microSD card overall is the SanDisk Extreme microSDXC for its consistent quality and obtainable price. Check out our other picks to see how they stack up to each other and find the best fit for your needs.

Tell me you need a microSD card and chances are that this is the one I’ll recommend. I’ve been using SanDisk microSD cards in smartphones, tablets, action cams, dashcams and drones for years now, and I’ve not had one let me down.
And quality doesn’t have to come at a price either — you can pick up a 1TB card for under $100.

- Comes with microSD to SD card adapter
- Not come across a counterfeit of this brand
- Can be pricier than other options
- Not as fast as some of the other cards
Tech specs: Capacity: From 32GB to 1TB | Offload speed: Up to 100MB/s | Write speed: Up to 60MB/s | Performance rating: 4K and 5K UHD-ready with UHS Speed Class 3 (U3) and Video Speed Class 30 (V30)
This is the card I recommend to those who either are in love with the Amazon Basics brand, or who are scare to buy another brand for fear of getting a counterfeit card.
I’ve used these cards a lot in applications where speed is not a concern — such as dashcams — and they’ve all performed as advertised.
- High performance

When I want speed, these are the cards that I turn to when I need to record a lot of data. With write speeds topping at 250MB/s, these are the cards I choose when I’m working with 5K video, either on the ground in action cameras or in the air with a drone.
- High endurance
- Fast enough for 4K video
- 5-year warranty
- Capacity tops out at 256GB
Tech specs: Capacity: From 32GB to 256GB | Offload speed: Up to 100MB/s | Write speed: Up to 40MB/s | Performance rating: 4K and 5K UHD-ready with UHS Speed Class 3 (U3) and Video Speed Class 30 (V30)
If you’re going to be doing a lot of writing to a microSD card, these are the cards for you as they are designed to offer up to 16 years — an incredible 140,160 hours — of continuous recording time for the 256GB version, while offering read and write speeds of up to 100 megabytes per second (MB/s) and 40 MB/s, respectively.

- Trusted brand

- Lifetime warranty
- Pricier than the competition

It’s impossible to cover storage media for cameras without including Lexar, as it’s one of those brands that’s been around since the dawn of storage. Great performance, excellent limited lifetime warranty, and another brand that’s not let me down.
ZDNET’s pick for the best overall microSD card is the SanDisk Extreme, but narrowing down the best microSD card isn’t an easy task. That’s because you can have different cards for different applications. For example, one person might favor performance, while another might want high endurance, and another be budget conscious. Thankfully, there are numerous options for extra storage that can range from just a few dollars to over a hundred, with different storage offerings and read and write speeds.

ZDNET only recommends products we ourselves have tested or researched, and while there are many microSD options on the market, not every card is built the same. Here’s some other factors we considered when curating our top selections.
- Hands-on testing: Bottom line, many of the included options have undergone ZDNET testing and use in a variety of systems from cameras and drones to CCTV systems under both easy and harsh conditions.
- Brand trust: I’ve been a photographer and videographer for a couple of decades, and a drone operator for close to ten years, and during that time I’ve had the chance to use all these microSD cards in real-world situations. These are the brands of cards that I use and trust.
- Benchmarks: I’m also quite a nerd, and have carried out both real world and synthetic benchmarks on these storage cards. For benchmarking I use AmorphousDiskMark and BlackMagic Disk Speed Test.
No. In fact, I’ve seen people run into troubles and lose a lot of data with this, not because of the microSD card, but because of their own bad practices. A terabyte microSD card can hold a lot of data, but that can lead to problem if you don’t regularly empty it and one day your camera falls into the sea or your drone flies away never to be seen again.
This is why I prefer having a handful of smaller cards. This way I change them regularly and if I do lose data, the loss is limited.
Very robust!
They are waterproof, drop proof, wear proof, and resistant to magnets, X-rays and extreme temperatures.
It can be hard to do this. The way many find out is that their card either dies or doesn’t have anywhere near the stated capacity.
Other, more subtle giveaways include the printing on the card being poor quality or wrong, and cheap packaging.
The best way to avoid counterfeits is to buy from a reputable outlet.
Yes, but I’m going to steer away cheap or budget microSD cards, simply because my listing above has some great cards at a great price, and going cheaper is false economy.
But here are a couple of cards that might interest you — a 1.5TB card and a great value 3-pack of 128GB cards.
