SD memory card for android: which is better to buy for a phone and a tablet?

This article will tell you how to choose a SD memory card for your smartphone or tablet.

When choosing a memory SD card, which serves as a drive and storage of your data, it is worthwhile to fit on the basis of the goals on which device it will stand, since the fast data transfer speed is necessary for each device.

Therefore, today we will lay out on the shelves everything related to this topic, starting from how to buy a memory SD card and ending with what device, which memory card needs to be purchased.

Let us fuse and give some changes that the developers have today made.

Firstly, until recently, the developers released mobile phones with the possibility of a change SD-cards of memory, that is, it was removable.

Now we notice a certain picture of how the developers began to produce phones with an already installed, but not removable memory card, which determines such “biting” prices for modern mobile smartphones

How did such an innovation of developers in the release of such smartphones begin?

We all know the company Apple, which currently has a multimillion -dollar budget per year than all other similar companies. And all due to the fact that this company thought out "insane" The course associated with very profitable and profitable marketing, which at the same hour increased their annual budget at times.

For example, we will take a card Microsd with memory capacity before 16 GBor 32 GB, after all, for the price, if you buy it separately, it will quite cost you before 1200 rubles, if not less. But this is taking into account the fact that for such you buy the most high -class memory card, which will have an excellent speed of reading and data transfer, and by the way, this is regardless of the dollar exchange rate, even now.

As if you look at the difference in price, now we are talking about devices apple With memory volume 16, 32, 64 and 128 GB, then the oscillation between this or that volume is approximately $ 100, that is, they added $ 100 and you have a memory of 64 GB, added another $ 100, you have 128 GB.

Here principle u apple, and not only with them, but also most companies that produce expensive and modern smartphones.

By the way on this principle samsung company I released my gadget Samsung Galaxy S6. In this regard, the people who were waiting for his exit and wanted to acquire him were adjusted into a stupor and surprise when they learned that in Galaxy S6 Memory card department it will not be removable.

Although, if you observe many budget smartphones that produce a whole line of equally popular companies, you can see that there is the possibility of installing a memory card to this day.

How are SD memory cards divided?

To date, they are implied by classes, each of which has its own speed of reading and data transfer. Suppose a memory card of the 10th grade implies that the speed of reading and data transfer will be about 10 Mbps, that is, in fact, such speed is average, but still it is much lower than the speed of internal memory on the magnificent Samsung Galaxy S6 .

Why do smartphone manufacturers began to produce them without the possibility of installing a memory card?

The problem of this is that almost all people are trying to save, for which they buy the cheapest memory card, but with a large amount of memory, and this, in turn, is very unprofitable for developers. That is why they began to produce modern smartphones on the principle of marketing, which was invented by Apple.

What types of memory cards exist?

There is everything 4 types of memory cardswho go to sD (SDMC) format.

Let's analyze each of them, and also find out in detail:

SD (SDMC) - This format is perhaps the very first of all that are available. It combines with all digital devices that support formats such as SD, SDHC and SDXC.

• Maximum memory - 4 GB
• File recording and transfer speed - 12.5 MB/s
• File system - FAT16

SDHC (SD High Capacy) - This is the next level of SD memory cards, but with a higher capacity. The only difference from the previous one is that this type is incompatible with digital devices that have support for SD format.

• Maximum memory - 32 GB
• File recording and transfer speed - 12.5 MB/s
• File system - FAT32

SDXC (SD Extended Capacy) - a more modernized level of format and type SD format, which has a more expanded memory volume, and is also provided with another file system. The SDXC type is maintained only on digital devices, the production of which was carried out after 2010.

• Maximum memory - 2 TB
• File recording and transfer speed - 25 MB/s
• File system - Exfat

SDHC I or SDHC II - This type has the highest speed of information exchange precisely due to the fact that the tire system is modernized there UHSwhich is deciphered as Ultra High Speed Or translated Ultra high speed.

Uhs i - She has two architectures that differs in the rate of exchange, namely 50 MB/s And 104 MB/s.

UHS 2 - a more advanced generation, which in the same way has two architectures for a faster exchange of information, which is 156 MB/s And 312 MB/s. In this case, this tire uses a new data transfer mode, which is 4 bits.

What classes of SD memory cards exist?

Now exists Total 4 classeswho are responsible for speed \u200b\u200band purpose.

• Class 2 - This class has a speed of about 2 MB/s, and is also designed to record a video with standard resolution
• Class 4 - This speed is about 4 MB/s, but this class allows you to record videos as HD 720p, as well as Full HD 1080P/1080i
• Class 6 - The speed of this class is about 6 MB/s and is mainly used for game consoles, something like Xbox One, Xbox 360 and PS 4.
• Class 10 - This type of class is the most powerful, and also has a multimedia transmission rate and 10 MB/s data, which is able to record videos as Full HD 1080P and subsequent fixation of HD Stills

Which memory card is best suited for android or tablet?

There is no concrete answer here, and the choice of memory card is individual, since the purpose of its use can be different, but still many buy a memory card to take pictures and recording videos, so let's calculate how much each amount of memory is enough.

Suppose you shoot video in Full HD format and take photos in JPEG format

• 2 GB is approximately a recording of a 2-minute video or about 250 pictures
• 4 GB is about a 5 -minute video recording or about 500 shots
• 8 GB is approximately a record of a 10 -minute video or about 1,000 pictures
• 16 GB is approximately a record of a 20 minute video or about 2,000 pictures
• 32 GB is approximately a recording of a 40 minute video or about 4,000 pictures
• 64 GB is approximately a record of an 80 minute video or about 8,000 pictures
