Though microSD cards have a tiny size they hide plenty of useful options. Here you can find some tips how to choose the best microSD – what information you should be aware of before the purchase and what to pay attention at when buying a card. Remember that the choice of microSD card is the same responsible process as the purchase of NAS or external hard drive for your PC. Therefore we offer you the list of best microSD cards to choose from.

How to Choose the Best microSD Card


There are two main types of microSD cards – SDHC (Secure Digital High Capacity) and SDXC (Secure Digital eXtended Capacity). The key difference is their storage. SDHC cards offer from 4GB to 32 GB while SDXC cards contain from 64GB to 2TB.

Another thing you should keep in mind is that some devices can accept only SDHC microSD cards. For example, such mobile consoles like the Nintendo 3DS work with SDHC cards only. Still, today plenty of devices are compatible with the SDXC microSD cards as most phones support namely this type of cards.

Speed Classes

Such feature as speed class is a key one when choosing the best microSD card. Nowadays there are such speed classes as 2, 4, 6 and 10. Obviously, the higher class your microSD card has the better and faster performance you will experience. The numbers of each speed class mean the write speed in MB/s (megabytes per second) – e.g. Class 10 = 10 MB/s.

There is no doubt that it’s always better to have a higher speed class. Still, if you are going to record high-resolution videos then you’ll need something more powerful like speed class 10 with UHS classification. UHS stands for ultra high speed and presupposes the highest speed of each microSD model. Cards with UHS classification are also divided into two types – UHS-I (up to 104 MB/s) and UHS-II (up to 312 MB/s).

Another thing you should know is card’s speed rating. There can be either U1 or U3 card’s speed rating. This rating denotes the lowest speed level your card can reach. U1 cards won’t let their write speed get lower than 10 MB/s while U3 cards support at least 30 MB/s. So, if you are buying a card for 4K videos then you will need U3 card’s speed rating.

By the by, if you need a card for video recording then pay attention to a video rating system which is usually marked like V90, V60, V30, etc. So, for 4K video you will need a card with at least V30 rating. Besides, if you can’t find such marker on your microSD then check its write speed.


One of the things you should always remember to do before purchasing a new microSD card is to check the maximum size of a card your device can support. If your device is compatible with cards of 32 GB maximum then look for SDHC cards. In case it is compatible with cards of higher capacity then pay attention at SDXC cards (up to 512 GB).


It’s always necessary to check whether your device is compatible with the cards you are going to buy. For instance, there are cards that will be more suitable for Android-based devices or Raspberry.

Still, there are some other sides of compatibility you should be aware of as your device isn’t the only thing the card must be compatible with. The point is that some microSD cards are more suitable for GoPro products while others, for example, for Nintendo Switch.

Extra Options

A lot of microSD cards have some additional options. Among them, you can find SanDisk Memory Zone App, which automatically moves files from your device to your memory card to free up space, and file recovery software. What is more, microSD cards can be waterproof, X-ray proof, static proof, temperature proof, etc.

Lexar Professional 667x microSDXC card is a device that offers great sequential read/write speeds (100MBps/90MBps), combined with a lifetime warranty and decent durability.

It is compliant with numerous speed standards such as U3 and V30, as well as A2 that guarantees for the same sequential writing speeds as an A1 standard, but offers much faster random read/writes. Moreover, Lexar Professional 667x microSDXC cards come in three capacities (64GB, 128GB and 256GB) and are supplied with a very handy SD adapter.

Unfortunately, although the level of the card performance is great, that cannot be said about its quality control that obviously degraded from the past time, and even though the number of complaints isn’t too big, they still exist, which wasn’t that often the case with previous card generations.

Of course, that doesn’t change the fact that Lexar Professional 667x microSDXC is still one of the best microSD cards available; however, it is not as flawless as Lexar used to be.

MLC is actually more reliable than TLC, which is what is commonly found, there are no more SLC cards of high capacity/speed except for industrial applications which cost a lot more.
