Any modern gadget - a smartphone, tablet, player or camera - has one common feature. They all work with digital data that requires storage space. It is for this reason that when choosing a new device, one of the criteria is the amount of free memory it has. Most devices have the ability to use external memory cards in hardware. This is convenient - you can change and increase the volume if necessary. In addition, this method reduces the cost of a mobile device, since it allows the manufacturer to reduce the size of the built-in memory.
Almost immediately after purchasing a new smartphone or tablet, you also purchase a card to expand the memory. At the same time, users often do not pay enough attention to the issue of choice. And completely in vain. The performance of your device will depend on how reliable the memory card is and the speed at which it can exchange information. To understand which memory card for a smartphone will work better, let’s look at the types and types of chips on the market.
The most common memory cards on the market are SD type memory cards. There are several varieties of them (differing in size). The SDHC memory card type already has a larger capacity. And the most modern media, the volume of which can be more than a terabyte, are SDXC cards.
At the same time, in mobile devices it is common to use cards of a smaller size (but not in volume). This is miniSD and microSD cards, which, due to their miniature dimensions, take up virtually no space in the device. In addition to various formats, types and sizes, memory cards are also divided into data transfer speed classes.
Speed classes
The most important characteristic for a memory card is the speed at which it can record and transfer data. The high speed of data exchange with the device allows you to quickly save and open photos, videos, and listen to music without noticeable slowdowns or application crashes. To make it easier for users to understand, the speed classes (SD Class) are divided as follows:
- 2 - recording speed from 2 Mb/s;
- 4 - recording speed from 4 Mb/s;
- 6, 10, 12, 16 and higher - respectively, the class indicates the minimum speed at which the memory card writes data.
It is the speed class, in addition to the volume itself, that you need to pay attention to when choosing a memory card for a mobile gadget.
Now let's put this information into practice. So, to expand the memory of your smartphone, you decide to purchase an additional memory card. First you need to decide on the format that your model supports. It is preferable to buy a memory card of the exact format recommended by the smartphone manufacturer. Despite the fact that there are numerous adapters and adapters on the market, their use is undesirable, since they may negatively affect the speed and stability of the chip.
After choosing the format, find out what speed class is needed for your smartphone. This is necessary to ensure optimal mode work when exchanging data between the device itself and the memory card. The fact is that for large cards this is a fairly important and critical parameter. At the same time, manufacturers of external memory cards, in order to reduce the cost of their product, may underestimate the speed. The cost of a flash drive directly depends on its volume and speed class. For this reason, you should not save on purchasing it. Especially if you plan to save photos and videos on the memory card and listen to music from it.
When choosing a card, you also need to remember about such a parameter as “lifetime”. Reliable manufacturers guarantee the operation of their products for up to five years. Practice shows that if the card is not physically damaged or demagnetized, it will work much longer. Often users focus on the number of recording cycles. Depending on the brand, you can find a guarantee for a million write operations with the card.
Note that everyday use (recording music files for playback, photos and videos, installing applications) makes it possible to use a memory card for decades. Given this life expectancy, we would recommend purchasing a memory card from a well-known brand (flash cards from Kingston, SanDisk, Transcend or Toshiba have proven themselves to be excellent), choosing a higher speed class, so that over time you can use it in a new smartphone or tablet.
Powerful, productive and inexpensive
In addition to a fast memory card with a large capacity, to confidently work with photos, videos, music and various applications, you need a powerful smartphone. Despite the fact that today there is a fairly large assortment of mobile gadgets on the market, making right choice not so easy. Especially if you have a limited budget allocated for the purchase. In this case, you have to refuse to purchase flagship models famous brands. What to choose - a device from a “fashionable” brand of the second, or even third line? Or prefer a top model from less famous manufacturer? Let's reason.
What is attractive about flagships, regardless of the company name? First of all, this is the implementation in the model modern technologies, the use of high-quality and reliable modules, wide functionality and powerful equipment. And if first-line brands charge exorbitant prices for such models, then companies that do not include multimillion-dollar advertising and marketing budgets in the cost of their products to promote a big brand name can offer consumers a much more interesting pricing solution. As a result, we get an excellent opportunity to become the owner of a powerful modern smartphone on a fairly limited budget. An excellent demonstration of this statement is the line of mobile devices from the young British brand Wileyfox.
Wileyfox entered the market in October 2015. Behind short term The brand's products began to be in high demand among users. This success is explained by the fact that each smartphone in the Wileyfox family has received the qualities and properties most in demand on the market. First, all models have a stylish modern design. Secondly, each device supports working with two SIM cards and 4G LTE data networks. Third, each smartphone stands out for its excellent technical characteristics. And most importantly, the company’s pricing policy makes the devices as affordable as possible on the market. A striking example This is what the brand's flagship model, the smartphone, serves.
The smartphone has 3 GB of RAM and has 32 GB of internal memory. This volume is quite enough to install and run the most resource-intensive applications. The device supports work with microSDXC memory cards up to 128 GB. This means you won’t have problems with running out of space to store photos, videos, music and other data. If desired, you can use the device as a navigator - it has the appropriate modules installed, and a high-speed memory card can accommodate great amount maps downloaded for the application along the entire route.
The model received a high-quality 5.2-inch Full HD IPS display. The originality of the style and attractive design of the model is emphasized by the slightly rounded 2.5D edges of the screen. The smartphone demonstrates high performance, which is provided by the powerful modern Cortex A53 MPcore chipset. It is also worth noting the high quality of photos and videos that can be taken with a 16-megapixel camera. Selfie lovers and users who prefer to communicate via video calls will appreciate the 8-megapixel front camera.
It is worth dwelling on such advantages of Wileyfox Swift 2 X as the ability to work with two SIM cards. Considering that you can use any slot to connect to high-speed 4G Internet, this is very convenient. In one slot there is a SIM card for voice services, in the other - for mobile internet. This will allow you to choose the optimal tariffs from mobile operators and save money while receiving quality services. At the same time, you can use any SIM card to access the Internet by simply assigning the desired slot in the menu. We also note support for such modern technologies as the fingerprint method of unlocking the device and NFC support (this technology is used for synchronization with accessories and payments using a smartphone).
And the biggest advantage is the price. The cost of Wileyfox Swift 2 X when ordering on the official website is only 12,990 rubles.
Conclusion
Now you know the differences between memory cards used in mobile gadgets. In addition, you can now choose the right memory card for your smartphone so as not to reduce the performance and speed of the device. And most importantly, we told you that today on the market you can buy a powerful, modern, productive smartphone at an extremely attractive price.
As you know, memory cards (flash cards) are used to store information and significantly expand the capabilities of the phone. In general, a mobile phone itself in its pure form does not need additional memory; the minimum provided by the built-in memory is enough for it. The first phones had an address book and the ability to receive or send messages, and kept a log of recent calls and messages. Even modern models are sometimes limited to built-in memory, while having an additional, extensive set of new functions. The point is that in Lately The mobile phone is no longer just a means of communication. New functions are increasingly being added to it, such as built-in MP3 players, cameras, and the situation has begun to change radically. Many new tasks require more memory to run. And now you already want to increase the memory capacity of your phone.
Often a memory card is not supplied with the phone, but it is usually not large enough, or maybe you just want to exchange the old one for a more capacious one. It is worth noting that not every flash card will be compatible with your phone model. There are a huge number of types of memory cards and adapters for them: CompactFlash, xD-picture and Memory Stick SD/MMC and others. Look in the manual or on the manufacturer's website for this information. Sometimes it happens that the old phone firmware (the program inside it) does not support cards larger than a certain size. Sometimes a simple flashing helps - and now the phone happily accepts the new card and you can safely use it.
When choosing a card, it is a good idea to pay attention to the manufacturer of this card. There are a number of manufacturers that have proven themselves very well: such as Transcend, Apacer, Kingston, Kingmax, SanDisk, Sony. They usually have the following guarantee:
- Transcend – 2 years;
- Apacer – 3 years;
- Kingston – 3 years;
- Kingmax – 2 years;
- SanDisk – 5 years;
- Sony – 1 year (a warranty of up to 5 years can be found abroad).
It should be noted that when purchasing a card, for example, with a capacity of 1GB, you will only get 900-950 MB available for work, since part of the card is occupied by information to protect the card from failures, file data, file system markup and other service information.
One of important parameters map is information about the speed of the map. It is easy to translate the mysterious designation, for example, 20x, it means 3 MB per second. That is the average size mp3 file. How is this calculated? Elementary: “1x” is approximately equal to 150 kb per second. Well, then the multiplication table works.
Well, the card has been purchased. You can stop here and start using it, but there are some nuances here too. Of course, there are Bluetooth, IrDA, GPRS and other options for data transfer. But to connect your phone with your home computer (or laptop), you will need either the same Bluetooth adapter, or a Card-Reader (a card reader is a device for connecting a flash card). The card reader will provide higher data transfer speeds and is quite universal, that is, you can easily use it for memory cards different types, and not only for mobile phones. Therefore, you should not save 10-15 USD. on purchasing a mid-range card reader. note that modern model must support USB 2.0 or FireWire interface.
Let's look at some common problems. If your phone does not “see” the memory card or gives an error like “Memory card access denied”, this is not yet a reason to run to the store or service center not to replace it. Initially, you should check whether it is inserted well. Oddly enough, the “remove and insert” procedure helps in half of the cases. Well, if that doesn't help, you can format the card. If the phone simply does not see it, then you will definitely need a card reader, otherwise formatting can be done from the phone. How to do this is usually described in the phone manual.
It's another matter if you use a card reader. We connect to the computer and if the OS is Windows, then right-click on the icon of your card in My Computer, and Properties->Tools->Check Disk [Run a scan, correcting damaged sectors]. Most often, this will fix file system errors and allow your memory card to work normally. Well, if that doesn’t help, then right-click on the icon -> formatting. If this does not help, then perhaps your phone does not support FAT32 and repeat the formatting by selecting the FAT file system. Sometimes it happens that after formatting in the card reader, the memory card needs to be formatted in the phone.
ATTENTION: formatting will completely destroy the information on the media, so before doing this, if possible, save all data from the card.
In order for your memory card to properly serve you throughout its entire resource (about 5 years of use), follow several rules:
Physical damage is contraindicated (the card cannot be bent, thrown, etc...);
Do not keep the card near heat sources, direct sunlight, or humidity;
the card is sensitive to electrostatic discharges (be careful with it when you pick it up);
Never disconnect the card while transferring information (you may lose both the information and the card).
Another feature is that SD and MMC cards, as well as adapters for these standards, can be blocked for rewriting or deleting. This is done manually on the memory card/adapter itself. So if you suddenly can’t write something to the card, check to see if it’s just blocked.
And finally. If your memory card begins to require a password, but you do not know it, then there are specialized programs for restoring it. N So you don’t have to rush to the service center. Leave this in case you were unable to restore it yourself.
Which memory card is best for a smartphone? MicroSD or microSDXC? What does a card class mean? What class are the best memory cards for phones?
The best memory cards for a smartphone must meet the following requirements: maximum speed data transfer when reading and writing, sufficient volume and reliability. And one more, largely decisive condition: does your phone support this or that type of memory card? We will talk about all this.
Memory card class for smartphone C2 - C10
Memory card classes C2 - C8 are gradually becoming a thing of the past. The market presents mainly cards of the tenth class (C10). They cost no more than “junior” models, are produced by famous and respected brands, and are protected from dust, water, heat, cold and X-rays. In a word a good choice in every way.
However, a few words about the class of the memory card need to be said. The numbers in the class indicate the minimum data speed when recording:
- a class C2 card writes data at a speed of 2 MB/sec and higher;
- C4 writes at 4+ MB/sec;
- C6 operates at speeds of 6 MB/sec;
- C8 - at speeds above 8 MB/sec;
- C10 - the fastest class - from 10 MB/sec.
Reading speed is usually even higher. In general, everything is clear with the C-class; it couldn’t be simpler.
Which class of memory card is best for a smartphone? Obviously class C10. How to make sure that the card belongs to this class? It’s very simple - there is a letter C on the card, inside which the number is its class (see photo above).
UHS standard
Now let’s talk about why C-class memory cards for smartphones are gradually becoming an anachronism. Manufacturers have developed new standard UHS (Ultra High Speed) which guarantees a minimum speed of 10 MB/sec.
The UHS standard provides two speed classes:
- UHS Speed Class 1: minimum write speed of 10 MB/sec.
- UHS Speed Class 3: minimum write speed of 30 MB/sec.
The actual write/read speed reaches 40-90 MB/sec. In theory, the best memory cards for a smartphone (U-3) can record data at 300+ MB/sec, but in reality this speed is not needed. Even for recording 4K video, more modest speed indicators are sufficient.
Which memory card is best for a smartphone? On which there is a marking U3 - the letter U with a triple inscribed in it (see illustrations). U1 will also work, although the first option is still preferable - UHS U3 speed class.
The best memory cards for a smartphone: UHS-I and UHS-II formats
In fact, digital technologies we have moved even further away from the C-class memory. The UHS standard has two data transmission formats - UHS-I and UHS-II. They are also marked with Roman numerals.
Unfortunately, today the best memory cards have the UHS-II format, but it is not supported by any smartphone. We checked the information, but did not find phone manufacturers that implemented the UHS-II format in expansion slots. If you have such data, share it in the comments below the article.
Luckily, UHS-I and UHS-II are backwards compatible. That is, you can safely put a UHS-II card in your smartphone, and it will work, but the data transfer speed will be limited by the UHS-I format. Which, however, is enough.
Smartphone memory card type: microSD, microSDHC, microSDXC
And now very important point- type of memory card depending on capacity. Here you can find three options:
- microSD - maximum capacity 2 GB.
- microSDHC (High Capacity) - volume from 4 GB to 32 GB.
- microSDXC (Extended Capacity) - from 32 GB to 200 GB (in theory - up to 2 TB).
When choosing a memory card for a smartphone, you need to take into account that not all models support microSDHC and microSDXC card types, and there is no backward compatibility, as is the case with the UHS-I and UHS-II formats! Therefore, consider the following:
- Map microSD memory suitable for a smartphone in any case - this type is supported by all mobile devices.
- A microSDHC memory card is suitable for a smartphone whose specifications indicate that it supports such cards.
- microSDXC memory card - can be installed if the technical characteristics of the phone clearly indicate that the format is supported. Or it is written that the memory is expandable to 64-128 GB.
If your smartphone supports microSDXC, you can also install a microSDHC card.
But with support for the microSDHC format, you can no longer install microSDXC!
Results
In general, this is where the conversation about the criteria for choosing a memory card can end. Instead of results, we offer an algorithm that will help you choose best map memory for your smartphone:
- Find out what type of memory card your phone supports: microSDHC or microSDXC. If microSDXC, you can buy any memory card. If microSDHC - only microSDHC and microSD.
- Look for cards rated UHS U3, although UHS U1 will do just fine. C-10 class will be the default for such cards; manufacturers may not even indicate it.
- Don't overpay for UHS-II cards. It is still not supported; UHS-I is sufficient for a smartphone.
- Choose cards from trusted manufacturers: Kingston, SanDisk, Samsung, Sony.
In many devices that we use every day. At the same time, memory cards are lost and damaged much less often - if only because they are usually left in the slot, and not carried in a pocket or with keys.
The main characteristic of a memory card is capacity. Of course, read/write speed is also important, but only for solving certain problems. How to choose a suitable memory card? Let's figure it out.
Main and main
When choosing a memory card, you need to follow two key rules:
1. The type of memory card must match the type of slot in the device.
Of course, you can take a microSD card complete with an adapter, for example, a proprietary 64 GB KNOW-HOW model, and use it in both types of slots.
But it’s better to purchase your own card for each device - firstly, adapters are often damaged and are not sold separately, and secondly, they are usually needed only in in case of emergency– when you need to quickly copy information from one device to another.
Devices that most often support microSD cards:
Smartphones
Tablets
Book readers
Navigators
Action cameras
Devices that usually have an SD card slot:
Cameras
DVRs
Car radios
external HDs
Receivers
2. The capacity of the memory card should not be greater than the maximum supported.
What happens if you insert a memory card of a larger capacity into the device slot than it supports? An error will occur: either the device does not recognize the card, or will not “see” the data recorded on it. The device may also prompt you to format the memory card - this will erase all data on it and change the available capacity to the maximum allowed. As a result, you will, for example, pay for a 128 GB card and receive an 8 GB card.
Volume depends on content
What will you use the memory card for? What data do you plan to store on it? This is largely determined by the device you are buying the memory card for.
It is necessary for users of smartphones and tablets, as well as car radios, to store their favorite songs and other audio files on a memory card. Most often, music is recorded in MP3 format, for which there is conditional rule– 1 minute of audio takes up 1 MB of memory on average. The length of the composition rarely exceeds 3-4 minutes. Thus, more than 1000 songs will fit on a 4 GB memory card. Agree, you are unlikely to need more space for your favorite music.
It all depends on the format and quality of the recording. If your smartphone or action camera shoots in 4K resolution, feel free to take a 64 GB or even 128 GB memory card. For DVRs that record in FullHD resolution, a 32 GB card is on average sufficient, but it is better to immediately take a 64 GB SD card (Transcend Ultimate or Transcend Premium). For models shooting in HD, you can buy a 16 GB card, but it’s better to play it safe and choose the 32 GB option. By the way, if the DVR records cyclically, replacing old videos with new ones, we recommend ordering cards with the maximum supported capacity - situations on the road vary.
Compact cameras and smartphones today take photos in resolutions from 5 to 20 MP or more. Consider three points: what format are you shooting in (standard, HDR, RAW), what maximum amount You take frames a day in advance and store photos as you are used to. In the standard format, each file takes up less space; in HDR and RAW, its volume increases several times. If you don’t take photos very actively, a small memory card (4 GB or 8 GB) will be enough; if you go on a trip and are unlikely to be able to immediately copy pictures to a PC or upload them to online storage, take a card of the largest possible capacity and with an adapter. A microSD of substantial capacity will also come in handy for those who like to show photos and videos on their smartphone to friends and family.
Applications
How more powerful smartphone or tablet, the larger the memory card capacity for it should be. The logic is simple: higher performance means you can play the most difficult games, which occupy several gigabytes.
Even if the application size on Google Play is less than 100 MB, do not be surprised when the game prompts you to download a gigabyte or two when you first launch it additional materials. So check the maximum memory capacity your cool smartphone supports and choose 32 GB, 64 GB or 128 GB cards. Well, what if the latest games If you don't get too carried away, then 8 GB or 16 GB will be enough to install all the necessary applications.
Modern flagship phones have an internal storage of at least 8-16 GB, but for some users this is not enough. In this case, you can solve the problem using additional flash memory. But you need to know how to choose a memory card for a smartphone so that it lasts a long time and does not fail at an unexpected moment.
Why is it needed?
A memory card is needed to expand the memory on a smartphone when the internal storage capacity is not enough to store existing data (photos, audio, video recordings, etc.). It is connected to a special connector in the case.
Modern smartphone models have a slot for MicroSD memory cards. It allows you to reduce dimensions and make the most efficient use of useful space inside the case.
Some smartphone models have a universal slot in which a nano-SIM is installed in one cell, and either MicroSD or a second nano-SIM in the second.
Before buying a MicroSD card, make sure that your gadget supports it. This information can be found:
- on the website of the smartphone manufacturer;
- in the instructions for the model;
- looking through the case for the presence of a slot on which “MicroSD” is written or a memory card is drawn.
Characteristics
If you are sure that your smartphone supports MicroSD card connection, you should know what characteristics to look for before purchasing it.
Memory type
There are three standards for MicroSD memory cards.
MicroSDXC cards are compatible with regular MicroSD slots, but are not recognized by the OS if it does not support this standard. Therefore, before purchasing, make sure that the removable media is supported by your gadget.
Recording class/speed
The speed of data exchange with the device (file read/write speed) depends on the class of the memory card. There are models of three speed classes on the market:
- Speed Class (denoted by the letter C);
- UHS Speed Class (U);
- Video Speed Class (V).
| Write speed | Speed Class | UHS Speed Class | Video Speed Class | Application |
|---|---|---|---|---|
| from 2 MB/s | Class 2 (C2) | — | — | Standard Definition Video Recording |
| from 4 MB/s | Class 4 (C4) | — | — | HD and FullHD video recording (from 720p to 1080p/1080i) |
| from 6 MB/s | Class 6 (C6) | — | Class 6 (V6) | |
| from 10 MB/s | Class 10 (C10) | Class 1 (U1) | Class 10 (V10) | FullHD (1080p) video recording, HD burst shooting, streaming and large HD video files |
| from 30 MB/s | — | Class 3 (U3) | Class 30 (V30) | 4K video recording (60/120fps |
| from 60 MB/s | — | — | Class 60 (V60) | 8K video recording (60/120fps) |
| from 90 MB/s | — | — | Class 90 (V90) |
The read speed of information for most memory cards is always higher than the write speed.
Volume
The capacity of modern MicroSD cards varies between 1 GB – 2 TB. The higher this indicator, the higher the price.
Each smartphone has a limitation on the size of the memory card connected to it: if the gadget is designed to work with a card up to 16 GB, it will not recognize a model with a capacity of 32 GB, or it will recognize it, but it will not work correctly.
The amount of removable memory your phone supports is written in the instructions or on the manufacturer’s website in the model description.
Manufacturers
- Kingston;
- Transcend;
- SanDisk.
Recently, SanDisk and Silicon Power have become popular due to the fact that they offer inexpensive but high-quality solutions.
File system
The disadvantage of the FAT32 file system, in which most modern maps memory is that it does not support volumes larger than 4 GB, which limits the amount of data written.
IN file system exFAT this restriction has been removed. But to connect such cards you need a smartphone with backward compatibility.
Durability
Data in memory cards is stored in cells that have a limited rewriting resource. It varies between 10,000 – 1,000,000 thousand cycles. In practice, this figure is much lower.
The longevity of a MicroSD card depends on the environment of use and build quality. Models from little-known or unknown brands are not subject to strict quality control during production, so they may fail within a few days or weeks of use.
If you don’t want to lose the data stored on your smartphone’s memory card, buy a model from a popular manufacturer.
