How to choose a memory cardMicroSD Tips
You should not look for SD and MicroSD memory cards with a capacity of less than 4 GB, simply because the price you pay for a capacity of two and four times more does not change much.
Make sure you factor in the shipping cost when ordering a microSD card online, you may pay more for postage than for a memory card, especially for low-end models.
If you are looking for a high capacity memory card (32 GB or more), make sure your device is SDXC compatible.
If you plan to move files to and from portable devices (tablets or smartphones), consider a microUSB memory card reader such as the Leef Access.
Avoid purchasing memory cards from vendors with few reviews, as such cards can easily be counterfeit. All the stores listed in our rating go through a multi-level check and are reliable.
128 GB and above SD cards are usually cheaper, as users usually choose 64 GB, as this number often corresponds to the maximum supported capacity of most mobile devices. Typically, MicroSD cards with an adapter are cheaper than equivalent SD cards.
Note that all digits are likely to be significantly smaller than what is formatted.
SD memory cards are usually divided into classes that give a rough idea of the minimum performance. A Class 4 card is guaranteed to offer at least 4 Mbps, while a Class 10 must exceed 10 Mbps.
Likewise, many manufacturers report available speeds in the form of "x" which is a multiple of 150 Kbps (the read speed of a standard CDROM). A 100x memory card is expected to deliver over 14Mbps.
If you're planning to buy MicroSD cards just for data storage, don't. Flash drives, being cheaper and more reliable, are the best choice.
Best cardsMicroSD Buyer's Guide
First of all, it is important to understand the MicroSD standards as well as all the labels. Exist Various types MicroSD cards even if they look the same.
Capacity
Let's look at MicroSDHC first. HC stands for High Capacity and covers sizes from 4GB to 32GB. Over 32 GB MicroSDXC memory cards, where XC stands for eXtended Capacity (Extended Capacity), and the largest cards in this category available for purchase are 200 GB. However, recent phones and tablets, including the HTC 10, claim to support MicroSD cards up to 2TB. Check your device's support before purchasing a card: many devices do not support SDXC and are therefore limited to cards up to 32 GB of memory.
Speed
There are three different speed standards and you may see more than one on the card. The original speed marking is marked inside the letter C (in the center of the image above). The number indicates the minimum sustained write speed, so the Class 6 card is capable of writing information at 6 Mb/s - that is, 6 megabytes per second. This is the sequential write rate and is only applicable when writing large amounts of data (such as video recording) to sequential memory locations. This does not apply to random 4 KB writes, a typical solution for phones and tablets, when small amounts of data are written to random places.
Most devices capable of recording HD video require a Class 10 MicroSD card, but most Class 10 MicroSD cards are capable of more than the minimum 10MB/s write speed.
This is where the UHS system comes into play. It stands for Ultra High Speed, and the letter U is used to denote the class. A Class 1 UHS MicroSD card writes at a minimum of 10 Mb/s, while a UHS 3 card records at a minimum of 30 Mb/s. With.
You can also see UHS-I or UHS-II on the map. This tells you what technology the Micro SD memory card uses. The UHS-I "Bus" can operate at up to 104 Mb/s, while the UHS-II bus can transfer data at up to 312 Mb/s. This does not mean that the card will read and write at these speeds, these are peak performance.
To take advantage of the higher speeds available with UHS-I or MicroSD UHS-II, you need a device that is compatible with this standard.
You can easily identify the UHS-II card because it has a second row of pins under the main dial. All cards tested in this article are Class 10 or UHS-I.
SanDisk showed off at MWC 2016 in Shanghai what the manufacturer calls its 256GB microSD card, the SanDisk Extreme microSDXC UHS-I 256GB, the world's fastest card.
The new map uses new system speed classification called Video Class. You'll see this system on cards soon, labeled V. Like the original class system, this means the minimum sequential write speed in MB/s and ranges from V6 to V90.
Best cardsMicroSD 2018: Temperature, X-ray and durability
MicroSD cards are small and easy to lose, but in addition to buying a dedicated case for your card collection, it's important to choose cards that can survive travel and any other factors that could compromise their function.
Some manufacturers claim that their cards are waterproof and also X-ray resistant. However, these characteristics are relevant for almost all MicroSD cards. The data is not stored magnetically, so an airport scanner shouldn't be a problem, as long as you're not trying to read or write data to a non-waterproof card reader underwater, the MicroSD card should be able to survive surface moisture.
The cards can also carry a suitability rating at certain temperatures, say -25 to +85 degrees Celsius, resist shock and shock, and much more. As long as you are willing to pay more for one of these cards, you can qualify for warranty if it suddenly fails because it has been exposed to high temperatures or "shocked".
The warranty, therefore, is the most important of all these things: check not only the duration, but also the conditions covered by the warranty.
The best memory cardsMicroSD: Which card to buy?
Our main recommendation is to stick to well-known manufacturers who can provide a guarantee for their cards. Reputable manufacturers include: Toshiba, Samsung, SanDisk, Lexar, Kingston, and Verbatim, among others.
There are many fake and low quality MicroSDs out there, so make sure you buy from a reputable supplier. If you see a card on Avito that is significantly cheaper than you expected, don't rush!
Before you buy a MicroSD memory card, check the maximum capacity of the device. Some mobile devices are limited to 32 GB because they are SDHC and not SDXC. It's tempting to get a 128GB card, but it just won't work if the device can't access it.
Quadcopters / Action cameras
If you're buying a MicroSD card for 4K video recording, look for a UHS-I Class 3 card. Many also recommend the same cards for Full HD (1080p) video recording, especially on high frequency frames.
Phones / Tablets
It is difficult to orient the buyer here using General characteristics because these devices rely on small file transfer speeds, which is an important difference. We'll take a closer look at map matching mobile devices in the reviews below.
It would seem that it is difficult to buy a memory card. Decided on the required volume, found profitable proposition and bought. It is because of this approach of users that some manufacturers flagship smartphones with expandable memory. If you have a microSD card handy, take a look - how much is written on it. This information will help you make the right choice.
Why bother with all this?
This is the question to start with. Imagine that you have bought a new modern flagship smartphone with memory card support, for example, LG G4. Such a smartphone should easily cope with all tasks, but suddenly you notice that the camera and other applications of your smartphone do not work as fast as you expected. This is possible if you are using a memory card that is not fast enough, where photos are saved and from which your applications take data. However, nothing prevents you from paying a little attention to the issue and choosing the memory card with which the smartphone can please you all the time.
What is the difference between SDHC and microSDXC?
When buying a memory card, you should pay attention to these large four letters, but the difference between these two standards is only in the amount of data supported. SDHC (Secure Digital High Capacity) allows you to store up to 32 gigabytes of data, while SDXC (Secure Digital Extended Capacity) can handle 64 gigabytes or more. The problem is that not all devices support SDXC cards and such a large amount of memory. Check the information about the capabilities of your smartphone before buying a memory card for 64 or 128 gigabytes.
What does the memory map class say?
Cards microSD memory there could be 2nd, 4th, 6th and 10th grades, and that's what you should really look at. These numbers indicate the supported data transfer speed, and while a microSD memory card can write data at a minimum of 2 MB/s, a Class 10 memory card operates at a minimum of 10 MB/s. It's not that hard. It is important to understand that we are talking specifically about the minimum write speed, and with good cards memory data read speed can reach up to 95MB / s.
What does UHS mean?
Another piece of memory card information you might see is UHS-1 or UHS-3 compatibility. Such microSD memory cards began to appear in 2009. In theory, a UHS card can support data transfer rates up to 321 MB/s, but you should focus on the minimum speed: 10 MB/s for UHS-1 and 30 MB/s for UHS-3. In fact, if you plan to use the card in a smartphone, you should not focus on this, smartphones do not support UHS.
What else is important to know?
It would be nice to get a memory card from one of the trusted manufacturers, such as SanDisk, or Kingston. It is also worth paying attention to the cost. If you suddenly find a suspiciously cheap memory card, you should be wary of it.
According to AndroidPit
The amount of information required for work and play is increasing every day. The quality of photos and video files is increasing, and with it their “weight” is also growing. As a result, the built-in memory of our gadgets, especially from the budget segment, is sorely lacking. This problem is easily solved, especially in phones with a removable battery. Why in them, how to choose a memory card for your phone for any budget and many other issues will be discussed in this article.
Memory card. What is this?
The memory card is usually a small black rectangle, but sometimes appearance is different. Depending on the model, it has a different amount of memory. IN modern models a variety of gadgets use only one type of memory card - microSD, although there are a fairly large number of them.
Earlier when Cell phones just starting to get additional memory, each manufacturer tried to invent its own format, different from the others. For example, the memory card of an LG phone could not be installed in Nokia. Over time, this trend, as well as specific charging connectors, gradually faded away. This has its own plus, because, having changed the smartphone, now it is not at all necessary to re-purchase this important accessory for it.
What volume do I need?
When it comes to the size of your SD Card, the first thing to ask yourself is which files you work with the most. In order to orient ourselves at least a little, you can look at the following list, which shows the approximate size of the files we are used to:
- Melody or track - from 3 to 10 megabytes.
- Photo - from 1 to 5 megabytes.
- Film (depending on quality) from 700 megabytes to several gigabytes.
If you are used to using only high-quality content, then you will have to think about memory cards from 32 GB or more. If the card is needed only to store a small playlist and current photos, its volume can be easily calculated using the above information. We can definitely say that with large volumes of photos inner space is not enough, and a memory card is required. A phone with 2 GB of memory is simply not able to store the number of videos and photos that modern youth is used to taking.
Feature regarding the capacity of the new memory card
Probably everyone who has previously encountered memory cards or flash drives noticed that there is a little less space on them than stated by the manufacturer. Why does this problem occur and can it be fixed?
Actually there is no problem. The reason lies in the principles of calculating space by a computer or phone. We are accustomed to multiplying all quantities by a thousand, as, for example, in one kilogram there are a thousand grams. However, in computer world the calculation is carried out a little differently, and it is customary to consider a number of 1024 as a unit. As a result, such an error occurs on the missing 24 bytes to every thousand. Therefore, manufacturers should not be blamed for such a “shortage”, and an SD memory card with a “trimmed” memory is actually quite normal.
What is a memory map class
All memory cards are divided not only by volume, but also by class. Therefore, when deciding how to choose a memory card for your phone, do not forget about this parameter. The class displays the speed of writing any information to it. There are different classes of cards, but the most popular in our stores are 4, 10 and U1.
In fact, everything is clear with digital classes - a four is equal to a write speed of up to 4 MB / s, and a dozen - up to 10 MB / s, respectively. With the U1 class, it’s a little more interesting, since manufacturers promise speeds not up to, but from 10 MB / s, but what will be the maximum possible, you have to check on the spot. This class is considered a newer standard and an SD memory card marked with it differs in better side from their predecessors.
In addition to the above, there are also digital SD Card classes 2 and 6, as well as a new generation U3 class. Digital ones are no different from their predecessors, that is, they correspond in the same way top speed records. The U3 class is currently considered the highest and allows you to write information at speeds over 30 MB / s. But despite high level development of smartphones, so far none of them needs such a high speed, so we will not consider it in detail.
What do I need?
Let's take a look at what each class's memory map can be used for. This will be another step towards how to choose a memory card for your phone and not make a mistake.
- Class 2 memory cards - designed for data storage and represent the slowest and cheapest option. You can record music and video files on them, while the recording process itself will be quite lengthy. Problems may occur when viewing high-definition video.
- Class 4 memory cards are the most popular and widespread. Fully meet the high-speed needs of budget phones and smartphones related to multimedia files. Nevertheless, it is better not to use it for games and programs.
- Class 6 memory cards - may already be a replacement internal memory some electronic devices and are designed to record and store any type of files.
- Class 10 memory cards - the most speed view cards, the maximum capabilities of which can be used by any smartphone. Allows you to record video in high resolution and perform other tasks that require high-speed recording of information.
- Class U1 memory cards - are an improved class 10, a slightly higher write speed and significantly faster reading, as a result of which they can be used for program files, since loading from them will be much faster.
- U3 class memory cards are used very rarely, since their characteristics are only needed when recording video in 4K resolution, and the cost is very high.
What is the maximum memory card capacity supported by the device?
Often, most manufacturers themselves indicate in the characteristics of the phone or smartphone, what size memory card is recommended to be installed in the gadget. However, sometimes this information is not indicated directly, but using an encoding. different types kart. It's worth taking a look at the device's spec sheet to see which cards are supported. The following might be written there:
- microSD cards are an old standard that requires the installation of a micro-storage card of the phone with a maximum capacity of 4 GB. Sometimes some Chinese manufacturers write that cards up to 8 GB are supported with the same marking, but no more.
- microSDHC cards are the most common format among budget phones and smartphones today. It provides for the possibility of expanding the memory with cards up to 32 GB, which is quite enough for most users.
- microSDXC cards are a new format that allows you to work with volumes up to 2 TB. Often, cards of this size can be very high cost, but quite popular, inexpensive, and at the same time functional solution there will be an installation of additional memory of 64 or 128 GB.
How to choose a manufacturer
Really little difference between memory cards various manufacturers No. They are all quite reliable, so only the price or attractive appearance can become the final weighty argument when choosing. The speed of a card, as discussed above, depends only on its class.
Sometimes on older devices there is a situation when memory cards of the maximum volume for the gadget do not work from all manufacturers. What this is connected with, even the developers of this or that gadget cannot answer. For example, a similar question was previously discussed on the forums - I bought regular card memory, I didn’t see it point-blank, although it worked with other devices without problems. Therefore, when buying a memory card, it is best to take with you the device for which it is intended. In this way, you can avoid unnecessary stress associated with the return of an accessory that did not fit.
Instructions for inserting a memory card
How exactly and where to put the card itself is often written in the user instructions for the device. However, there is often missed another important point. Some devices can easily read data written to a card with a file system in one of the common formats. But at the same time, after prolonged use, failures may begin, which can lead to the loss of important information.
To prevent this from happening, it is recommended immediately after installation, while there is no data on the card, to format it directly using your phone or smartphone. Do not be too lazy to do this operation, because later it can protect you from unnecessary worries. This is where the recommendations on how to choose a memory card for your phone come to an end. We hope you will not have any problems when purchasing this accessory.
A memory card is needed to store information. In order not to lose valuable files, memory cards should be purchased only from trusted places.
How to use the memory card
The memory card is easy to use. In all modern devices There are special entrances for such cards. As a rule, they are located on the side or bottom panels. Usually, the device itself has a picture showing exactly how to insert the memory card (for example, beveled corner to the right). Insert it into the connector as it should, and start working with the equipment.
Some memory cards have an additional button. Lowering it down to the inscription Lock, you will block the card. Thus, it will be impossible to delete information from it, nor to write a new one.
How to check a memory card through a computer
The simplest of the options for checking a memory card and its volume is checking through a computer. You need to insert a memory card into a special slot in a computer or laptop (or using a card reader). Next, select a memory card in the detected devices and go to its properties. All the necessary information will be displayed there.
