Best micro SD cards for Samsung Galaxy, LG, Motorola, and Xperia phones (2021)
In 1956, IBM introduced the first disk drive in the world. It was as big as a vending machine, it cost more than a house, and it could only store 3.75 megabytes – about the size of a single song in MP3 format. Today, over 60 years later, a smartphone can hold several thousand times more data, yet fits in your jeans' side pocket. Boy, has technology evolved!

Storage space, however, is one of those things our phones never seem to have enough of. They are burdened by heavy apps and offline music, by high-resolution photos and videos, all of which eat up precious GBs.

That's why many smartphone makers, including Samsung, LG, Sony, and Motorola still allow storage expansion via micro SD cards, even on their latest and greatest phones. Not all micro SD cards are made equal, however. Not all of them can keep up with the read and write speeds certain tasks can demand – shooting 4K video or quick sequences of photos, for example. 

Also, micro SD cards come in a broad range of capacities, which might make picking the right one even more tricky. So, we thought we'd make your life easier by gathering up the best micro SD cards for any phone supporting micro SD storage expansion.

512GB micro SD cards (or larger)

Samsung Evo Select 

Available in a broad range of capacities, the Samsung Evo Select can provide all the space you may ever need on your phone. The largest offering in the series packs a whopping 512GB! This particular model is also not that expensive, considering the capacity. 

You can fit 77,000 high-quality audio tracks, 150,000 high-res photos, or 24 hours of 4K 60fps video on that card. For consumers who don't need quite as much space, the 128GB micro SD variant is the most cost-efficient in the series. 

The Samsung Evo Select micro SD cards offer up to 100MB/s sequential read speeds, which is more than enough for everyday tasks. These micro SD cards work great with tablets, laptops, action cameras, DSLR's, drones, smartphones, Android devices and more.

SanDisk Extreme 1TB

If you want the highest possible capacity and speed for whatever reason, you have to go to extremes. The SanDisk Extreme 1TB microSD card offers read speeds up to 160MB per second and comes with a record-setting 1000GB capacity. Of course, you must be prepared for the extreme price, too. 

The 1TB version normally costs around $269.99 but there are sweet deals out there and you should look out for them (the SanDisk Extreme 1TB micro SD card is discounted on Amazon right now).

If you pair this card with a Galaxy S10+ 1TB phone, you'll end up with more onboard storage than many laptop and desktop computers. The SanDisk Extreme 1TB is the biggest micro SD card available at the moment, though you should check if your phone supports SD cards with such capacity. 

There's also a lifetime warranty for this one, so you'll have peace of mind if you decide that you need that much storage on your phone. If you don't need that much storage, there's the 512GB variant, and it's considerably cheaper too.


High-endurance micro SD cards

Kingston Endurance

The Kingston Endurance is the best micro SD card for every video enthusiast out there. It's optimized to withstand write intensive applications such as home security & surveillance cameras, which means it will work great if you like to record long videos with your smartphone. 

Better yet, the A1 designation indicates the card's ability to handle Android applications great, as well. The card is available in capacities of up to 128GB and strikes a good balance between performance and cost. 

SanDisk High Endurance Video

It's true that high-endurance micro SD cards are perfect for dash cams, home monitoring systems and other video-intensive applications but that doesn't mean you can't use them in a smartphone. Quite on the contrary. 

Opting for such a card will grant you extra durability, especially if you overwrite the card often (record lots of videos, frequently install and delete apps.) You can get a 256GB model for around $40 and that's a bargain. 

Samsung PRO Endurance

Another solid option from Samsung - the Pro Endurance series. This microSD card is shockproof , waterproof, temperature proof, x-ray proof and magnetic proof. You don't sacrifice speed, though. It offers up to 100 MB/s read and 30MB/s write speeds, while maintaining best-in-class endurance up to 43,800 hours of 4K and Full HD (1080p) recording and playback.

Fastest micro SD cards

SanDisk Extreme Pro

SanDisk's top-grade micro SD cards offer read/write speeds up to 170/90MB per second making them one of the fastest micro SD cards out there (smartphones support UHS-I speeds, capped at 104MB/s but still, the Extreme Pro will get you right there.) 

This kind of performance allows them to function flawlessly with the latest high-end Android phones. The A2 rating indicates they're fast enough to work great with apps, while the V30 rating ensures they can be used for recording 4K video and bursts of photos. 

This card comes in four capacities, from 64GB right up to 400GB. You can get a nice 256GB micro SD card version and it will solve all your storage issues, no matter if we're talking about multimedia or apps.

 Affordable micro SD cards

Samsung Evo Plus 128gb

You don't have to cough out huge amounts of money to get a good micro SD card. The Samsung's Evo Plus range is one of the best-selling micro SD cards out there and for a good reason. 

You can get a 128GB version for around and it will get the job done for practically pocket money. It's a great package - decent speed, capacity, and price. The Evo Plus will tackle every task you throw at it. It's a standard when we talk micro SD cards. As simple as that.

Lexar 128GB Micro SD Card

Another affordable microSD card comes from Lexar and offers the same 128GB capacity for under $20. It's a good allrounder, not as popular as the aforementioned brands and models but a solid option nonetheless. 

You get up to 100MB/s read speed and up to 30MB/s write speed, water resistance, A1 rating for continuous 1500 read IOPS, 500 write IOPS, and of course, a great price.
