Whether you’re buying a 128gb Micro SD for your camera, phone or some other type of gadget, shopping for it may seem like an easy task to do. However, there’s a lot more to these storage cards than meets the eye. A MicroSD card is a reasonably cheap way of expanding your gadgets’ storage, but buying them or selecting the best one which suits your specific needs can be tricky.
Surprisingly, it’s easy to end up falling into various traps such as terrible performance, overpaying or worst, the card not even working at all.
If you’re in need for a new one for your mobile phone, tablet, camera or for some other reasons and, there are several factors you need to consider first before buying and we have all the key information covered here. Always remember that it sometimes pays to choose wisely.
Choosing the right MicroSD card
When looking for a MicroSD, it is essential to buy one that is just right for its intended purpose. This means that buying a card that’s not just large enough but also fast enough and not automatically the fastest or largest one out there. There are high capacity cards like UHS-II U3 that comes with a steep price but you will not always notice the benefits it offers.
When using a microSD card to increase the storage on your smartphone, then it makes sense to pick the highest capacity you can. At the same time, speed won’t be a major priority since you won’t be transferring large files back and forth frequently. The exception would be if you’re using a newer phone that can shoot 4K video. Just as with a 4K video camera (like the GoPro), large capacity and high speed are musts.
As a general rule, it’s always a good idea to buy specific cards for specific tasks. This way you can guarantee the best combination of speed and capacity for your hardware to give you the best possible overall performance.

Compatibility and formats
MicroSD comes in 3 formats; SD, SDHC and SDXC, which will determine whether or not the card you’re about to buy will be compatible with your gadget. Both full-sized and micro cards are based on the same spec and each format is defined in the SD spec, howeer the don not work in the same manner. For example, if the card slot on your gadget only supports MicroSDHC card, then a microSDXC card will not work on it.
It is important to check your device’s maximum size capacity before purchasing a card. Most devices usually can take up to 32GB, which is the SDHC standard limit.
Physical size
Hardware that supports microSDXC slots will not automatically support every size of card in this format. If you plan on using your microSD card with your PC say for moving files on and off, you need to make sure that your PC supports the file system that the card is formatted with.
Speed
There are two types of speed indicated on an SD card “C’ and “U”. Each SD or Micro SD card has a speed rating, called a class. Larger class numbers correspond to a faster level of minimum performance, allowing files to be copied or recorded at a higher speed. The class rating system is actually quite simple to remember: the number after each Class corresponds to the minimum sequential read speeds, in MB/s. So Class 2 is 2MB/s, Class 6 is 6MB/s and so on.
The U1 and U3 are UHS Class speeds that show the minimum write speed. U1 cards support at least 10Mbps write speed and the U3 cards will deliver at least 30MBps write speed. Note that these are minimum write speed values. It is possible for a U1 card to give a write speed greater than 10MBps, say 15MBps, as well. The Speed Class, that’s denoted numeric value within the letter ‘C’ on your microSD card also denotes the sequential write speed.
After Class 10, it gets a bit more complicated. An additional standard called UHS was introduced, which allows cards to reach higher speeds. In order to benefit from the increased performance of UHS, it needs to be supported by your hardware. UHS memory cards will work in older slots but with a reduced bus speed of 25 MBps.
The Speed Class indicates the minimum write speed of a memory card in MBps or megabytes per second. The four Speed Class are as follows:
UHS Speed Class on the other hand indicates the minimum write speed for microSD cards that support the UHS-I and UHS-II bus speeds. Its classes are the following;

Adapters
MicroSD cards can be placed inside a so-called passive adapters which allows them to be used in ports which are designed for larger storage cards. Most commonly, Micro SD cards can be placed inside SD adapters. This is useful for using a single card in multiple devices as well as using Micro SD cards in SD card readers.
SD v MicroSD
There are two forms of memory cards, SD and microSD. SD cards are basically used in bigger devices such as video cams and digital cameras. They are also a bit larger than your average postage stamp. MicroSD on the other hand are used more in gadgets like tablets and smartphones. They are smaller than full sized SD cards. There’s also a third form, the MiniSD, but this was used widely as a transitional form factor in the mid-2000s before the popularity of MicroSD. Today MiniSD cards are rarely seen.
