Best MicroSD Cards

best MicroSD cards

MicroSD cards have come a long way since we first started using them in 2003. In 2006, SanDisk revealed that they were producing a 4GB microSD card. Since then, the amount of storage on one of these cards has increased dramatically, even though the size of the card itself has not changed. Earlier this year, Integral Memory revealed a 512GB microSD card.

As these cards have grown in size, so too have our abilities to use them. They are now compatible with many technology devices we deem standard today and can be transported from one device to the other quickly. But as these cards have increased in storage capacity, so too have the number of options available. If you’re looking to purchase the best microSD cards, the information below should help.

You are a valuable part of our community, and we appreciate the fact that you come to us when looking for a review that you can trust.

We started by testing numerous different microSD cards for speed, accuracy, and durability. We moved the cards from device to device and completed multiple file transfers. After conducting our tests, we looked at reviews from other websites like Amazon. We understand that our team pales in comparison to the millions of people who use microSD cards, which is why we wanted to consider their opinions too.

Card's Manufacturer

From here, we accounted for the card’s manufacturer. Manufacturers with a trusted reputation were more likely to score well since we would know what to expect when dealing with these companies. Although we didn’t necessarily discredit those storage cards with less reputable manufacturers, we did conduct more research to ensure we could rely on them.

That led us to the ratings you’ll find below. We are confident that if you select one of the cards from the list below, you’ll be satisfied with its performance. Of course, we are always willing to make changes to improve our rankings. If you have a terrible experience with one of the microSD cards we’ve recommended, we encourage you to share.

Buyer’s Guide 

It seems that there are microSD cards everywhere you turn. Each one comes with unique specs and features. How could you possibly sort through them all and figure out which one you’d like to buy? Fortunately, this buyer’ guide can help. Below you’ll find the information needed to help you make an informed decision about the best microSD cards.  

Figure Out the Purpose of Purchasing a Card

The first thing you should do before you consider any other criteria is to determine why you would like to purchase a microSD card. As you’ll see below, cards can vary in both size and transfer speed. Knowing why you’ll use the microSD card could help limit the scope of your search, allowing you to focus only on the cards you’ll need.

If you plan on using the card as an external storage solution and do not plan on taking it in or out of your device frequently, storage capacity will likely be your primary focus. A perfect example of this is those individuals who use a microSD as extra storage on their cell phone. There’s a good chance you won’t be transferring data to or from the card frequently, so you’ll want maximum storage capacity.  

Compatibility

Before you begin searching for microSD cards, you should first confirm that your devices are compatible. That’s because there are three different types of microSD cards:

  • SD, which has a maximum capacity of 2GB
  • SDHC, which has a capacity between 2GB and 32GB
  • SDXC, which has a capacity between 32GB and 512GB

All three of these cards will fit into a microSD slot, but that does not mean that all three will function adequately. This is because you can’t use newer cards with older devices. However, you can use older with more modern units. For example, you could use an SD model in any microSD slot and expect it to perform to its maximum capacity.

However, SDHC cards will not work in devices that only support SD cards. SDHC cards will work in any device that supports SDHC or SDXC formats. Similarly, SDXC models will not work with any other slot. So, before you buy a card, you should check the compatibility of your device. Don’t buy a microSD card that is too powerful for your device.

Knowing the compatibility of your device will help make the search process much more manageable. You won’t waste time searching for cards that won’t function. Many retailers organize their microSD cards by size, so it should be easy to narrow down your choices. Additionally, some retailers won’t accept returns for cards that you have used.

You should also look into any software restrictions that could interfere with the compatibility of your microSD card. For example, some computers will not support a microSD card’s file format. While PCs are not as troublesome, those with a Mac may have some difficulty getting their hardware to cooperate with their SD card.

Consider the Card’s Speed

Once you have figure out your card’s compatibility, you’re going to need to consider the speed of the card. Speed classes indicate how fast your card can transfer files, based on megabytes per second. MicroSD cards come in speed classes of 2, 4, 6, and 10. So, a card in the second speed class can transfer files at a rate of at least 2 MBps per second, while a card in the 10th class transfers at 10 MBps a second.

However, there’s a catch to this. These classes represent minimum transfer rates, not maximum transfer rates. A card in the second speed class could write just as fast, if not quicker, than a card in the fourth speed class. Some may find discrepancies between the second, fourth, and sixth levels. However, there’s an understanding that the tenth class will be much faster than the rest.

Some manufacturers will list a maximum speed for their cards, which could help clear up any confusion. In our testing, we found that those that recorded their maximum speeds were noticeably faster than others. So, if you plan to perform large file transfers with your microSD card, and speed is one of your primary concerns, you should keep an eye out for manufacturers that list their card’s top rates.

Cost

When purchasing a microSD card, you don’t want to break the bank and overspend. However, you should be willing to invest a bit into a quality microSD card, especially if you are looking for a top-of-the-line card that provides maximum speed, capacity, or both. Similarly, you should be willing to pay more for a brand with who you’re familiar, and you know you can trust.

Unfortunately, there are fake memory cards that do not operate as they say they do. Often, consumers don’t realize they purchased a counterfeit device until their card’s storage fills up significantly quicker than they had expected. At this point, they’re stuck with their purchase, and they’ll have to either move files to continue using the fake card or spend even more money to purchase another.

Even if a card is not counterfeit, some brands are not as reputable or reliable as others. MicroSD cards can be susceptible to damage. Trusted brands do a much better job producing durable memory cards. Remember that if your card fails, you lose everything. That includes pictures, videos, games, movies, and music. You likely won’t regret paying more for storage you can trust.
