More than once or twice, smartphone users are faced with the problem of lack of their own memory on the phone. This issue has been partially solved in our time by increasing the volume in the smartphone itself, but for some, especially those who work in the field of SMM, marketing or often shoot videos, the standard amount of GB is usually not enough. Therefore, manufacturers, for quite a long time, have been releasing memory cards for different formats, for different connectors.

It all depends on what phone model you are currently using? Almost all flagships from well-known manufacturers do not have a slot for a memory card. This applies to phones with one SIM card. If we talk about gadgets that are designed for two – instead of the second, you can insert a drive. In this way, Chinese and Korean manufacturers compare favourably with Western counterparts, which typically do not provide for such a function.

But in most cases, we need a memory card for a smartphone. It can, for example, store media files – photos, videos – thus, a small amount of permanent memory of such heavy information is unloaded.

There are several card formats…

SD cards – Secure Digital – size 24 x 32 mm, which are used in laptops, cameras, camcorders and game consoles. microSD cards, which are 11 x 15 mm in size and are used in smartphones, tablets, audio players and e-readers.

Memory cards almost always come with an SD adapter, which increases the storage capacity of the smallest media.

Using an adapter, the same card can be transferred from a smartphone, for example, to a camera, game or TV set-top box. A microSD card with an adapter is a convenient, economical choice that saves not only material but also time resources.

Not all cards of the same size are the same. For example, microSD has several subtypes: externally they are no different: microSD: from 2 to 4 GB, they are almost out of circulation; microSDHC – high-capacity cards – from 4 to 32 GB; microSDXC: – Ultra high capacity cards – 32 GB and above, but cards up to 2 TB are currently available. The type of card is usually indicated on its front side with a special marking.

When choosing a memory card, it is worth remembering that each new generation is backward compatible with the previous one. That is, you can insert a microSDHC generation card into the microSDXC slot, and it will work. Unfortunately, this cannot be done the other way around. Therefore, before buying a drive, be sure to open the instructions for your device and carefully read what type it supports.

In addition, you need to consider how much memory your phone supports. It is very possible that he will not be able to overclock the amount that you technically want. Therefore, if a smartphone can work with 128 GB, then you should not buy a terabyte card.

Memory cards differ in data processing speed classes. Depending on this, they are marked from 1 to 10. These numbers indicate the speed of reading and data transfer.
