Micro SD cards have been an easy solution to our storage woes for ages. If your smartphone supports one, you can use it to store many things – your song collection, high-res photos and videos and much more. However, with this great responsibility comes the requirement of great power – something that you can ensure by picking the best Micro SD card for your smartphone. If you’re not sure how to go about that, scroll ahead to find out.

Which micro SD card is best for your mobile phone

You need to be aware of a few important factors when picking a micro SD card for your smartphone, such as:

  • Ensure support
  • Pick the right storage
  • Pick the right speed

Let’s talk about these below.

Ensure microSD card support

Ensure that your smartphone supports external storage. Some of them have a hybrid storage slot, which means you can either use a second SIM card or a micro SD card. If you have a hybrid slot and must use the second SIM, then consider using an OTG pendrive for external storage.

Pick the best capacity for your microSD card

If you check your smartphone’s specifications, you’ll find that the external storage support is specified up to a certain limit. This is because SD card storage is classified into SDHC, which goes up to 32GB, and SDXC, which goes much higher. Depending on which one your smartphone supports, you might have to restrict your choice of microSD card.

Pick the best speed for your microSD card

You can understand the speed of a microSD card by checking its standard, such as

  • Class: The usual class number ranges from 2 to 10 and denotes a speed of 2MB/s to 10MB/s respectively. It is depicted at the front of the card as a number within the letter C.
  • UHS: The UHS speed standard is denoted by the letter U and has three tiers - UHS-I, up to 104MBps UHS-II, up to 312MBps UHS-III, up to 624MBps. These cards work with older smartphones but at limited speeds.
  • App performance: Denoted by A1 and A2, this means a card is fast enough to directly store app data. This rating denotes a better Input/Output operations speed. Look for this rating if you intend to run apps off the microSD card.
  • Video Speed: Best sequential write speeds, which is what is needed for video recording. Choose this if you intend to shoot a lot of high-resolution videos.


Go for the card that best suits your purpose and go for a brand with a reputation for reliability. You don’t want to get a better deal at the cost of losing all your data down the line. Unreliable microSD cards can also lie about their performance levels, so always go for your choice from an authorised retailer.
