These are the best microSD cards for your phone (2018)
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 gigs. That's why many smartphone makers, including Samsung, LG, Sony, and HTC, still allow storage expansion via microSD cards, even on their latest and greatest phones. Popping in one of these cards is an easy and cost-effective way of adding additional data space to a Galaxy S9, Galaxy Note 8, LG G7, LG V30, HTC or Xperia phone.
Not all microSD 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, microSD 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 microSD cards for any phone supporting microSD storage expansion.
Available in a broad range of capacities, the SanDisk Ultra can provide all the space you may ever need on your phone. The largest offering in the series packs a whopping 400GB! Sure, this particular model is also quite expensive, but on the other hand, the investment could be worth it: you can fit 120,000 high-quality audio tracks, 50,000 high-res photos, or 13 hours of 4K 60fps video on that card. For consumers who don't need quite as much space, the 128GB SanDisk Ultra is the most cost-efficient model in the series, priced at around $30 as of this writing.
Since the latest SanDisk Ultra cards carry the A1 logo, they are capable of having Android apps run off of them without issues – something few microSD cards can brag with. However, when it comes to writing speeds, they are not as fast as some of the alternatives we'll take a look at next.
Kingston Canvas React
The Kingston Canvas React is the fastest-performing microSD card the brand has to offer for your smartphone, peaking at 100MB/s read and 80MB/s write speeds. Better yet, the V30 designation indicates the card's ability to sustain the speeds required for 4K video recording at high framerates. The card is available in sizes of up to 128GB and strikes a good balance between performance and cost. A lifetime warranty sweetens the deal with this one.
SanDisk Extreme Plus
SanDisk's upper-grade microSD cards offer read/write speeds up to 100/90MB per second and performance allowing them to function flawlessly with the latest high-end Android phones. The A1 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. However, they're a tad more expensive than other microSD cards and top at "only" 128GB of space.
Samsung Evo Plus
Samsung has a variety of microSD cards on sale, and the Evo Plus is ideal for use in high-performance smartphones. The higher-capacity 128- and 256-gigabyte models sustain high read/write speeds and offer plenty of storage space for your media. They're reasonably priced too. Just note that older, lower-capacity models of the Evo microSD cards perform more slowly when writing data. Counterfeits are also easy to come by, so keep an eye out for those.
