How to choose a microSD memory card for smartphones

Modern phones and tablets support only one memory card standard – microSD, and its variants – microSDHC и microSDXC. Therefore, products need to search for it with such connectors. But what kind of choose a smartphone memory card microsd and that more attention should be paid?

Make, that the smartphone has a microSD memory expansion slot

Some buyers are wrong in, that every smart phone allows the use of memory cards. But in reality, the situation is different. The growing amount of memory in the flagship model and the use of cloud technologies have led to, that many companies refused to from their smartphones read microSD card reader. With such a nuance may be encountered, eg, in all variations Samsung Galaxy S6, and Samsung Galaxy Note 5.

One side, Android system does not allow you to move apps to the memory card, but on the other - they can store photos, videos and music. In this way, decision to abandon the idea of ​​the reader is not, which approves advanced users.

The first conventional memory card used outdated today FAT16 system, which allowed a maximum 2 GB capacity. More recent models use a microSDHC FAT32 system, due to which media can have up to 32 GB. they, who want a memory card larger volume, You must become generous on the map sdxc with the exFAT file system from the theoretical to date with up to 2 TB.

The problem is that, that not all smartphones support microSDXC standard, and if they do it, as a rule, have the capacity limitation. So in this case it is necessary to review the characteristics of selected devices. for comparison – Huawei P8 supports microSDXC card, but only to 64 GB. Sony Xperia Z5 allows the use of models to 200 GB, and in LG G4 – to 128 GB. In turn, Kruger&Matz Live 2 only supports microSDHC memory cards up to 32 GB.

You can still find a model class 6 (6 MB / sec), but mostly dominated by the model class 10, which reach up to 10 MB / sec. They are ideal for storing high resolution pictures and record video. For this purpose there is also a class U1 cards (10 MB / s) and U3 (30 MB / s). Once again it should be emphasized, that is the minimum value, which such cards can achieve. Although theoretically map 10 Class is no different from U1 cards, however, the second will be much faster.

It should also pay attention to the data bus, which is designated as UHS. There are two standard: UHS-I at maximum speed 104 MB / sec and UHS-II, which can reach 312 MB / s. it, but, a possibility of the tire, rather than actual transfers, received via memory card. Besides, This type of model is mainly used only in professional devices. A smartphone for home use is fine class microSD memory card 10. It copes even with the preservation of video in 4K format.

Who is the manufacturer?

Finally, left to decide for themselves – any manufacturer to be trusted? This question is no single answer. Although memory cards are quite reliable products, you can always get on the model that is broken, and all data will be irretrievably lost. It should be noted, that model respected and well-known companies, this risk is minimized. There are several manufacturers, you can trust. Worth looking for a memory card brands such, as: SanDisk, Kingston, Samsung, Sony, A-Data, Transcend, Toshiba, Lexar. Each of these companies provides a reliable quality.
