How to choose a memory cardMicroSD: Tips

You should not look for an SD memory cards and microSD with a capacity of less than 4 GB simply because the price you pay for a container of two and four times more is practically not changing.

Make sure you take into account the shipping price when you order a microSD card via the Internet, you can pay more for postal expenses than per memory card, especially for low-cost models.

If you are looking for a large capacity card (32 GB or more), make sure your device is compatible with SDXC.

If you plan to move files on and with portable device (tablets or smartphones), consider the MicroUSB memory card reader, such as Leef Access.

Avoid purchasing memory cards from suppliers with a small number of reviews, since such cards can easily be fake. All stores in our ranking are a multi-level check and are reliable.

The capacity of 128 GB and above the SD card is usually cheaper, since users usually choose 64 GB, since this number often corresponds to the maximum supported container of most mobile devices. As a rule, MicroSD cards with an adapter are cheaper than equivalent SD cards.

Please note that all the figures are likely to be significantly less than indicated when formatting.

SD memory cards are usually divided into classes that give an approximate idea of \u200b\u200bminimal performance. CLASS 4 Map is guaranteed to offer at least 4 Mbps, and Class 10 must exceed 10 Mbps.

Similarly, many producers report accessible speeds in the form "X", which is multiple 150 kbps (read speed of the standard CDROM). It is expected that the memory card 100x will supply more than 14 Mbps.

If you plan to buy MicroSD memory cards just for storing data, do not do it. Flashki, 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 labeling. There are various types of microSD cards, even if they look equally.

Capacity

First consider microSDHC. HC means High Capacity (greater capacity) and covers dimensions from 4 to 32 GB. Over 32 GB of the MicroSDXC memory card, where XC means Extended Capacity (enlarged capacity), and the largest cards in this category available for purchase are 200 GB. Nevertheless, the latest models of phones and tablets, including HTC 10, declare MicroSD card support up to 2 TB. Check out the support of your device before purchasing a map: many devices do not support SDXC, so limited by cards up to 32 GB of memory.

Speed

There are three different speed standards, and you can see more than one on the card. The original speed marking is noted inside the letter C (in the center of the image above). The number indicates the minimum stable recording speed, so the Class 6 card is capable of writing information at a speed of 6 MB / s - that is, 6 megabytes per second. This sequential recording speed, which is applied only when recording a large amount of data (for example, when recording video) to serial memory cells. This does not apply to a random recording of 4 KB, a typical solution for phones and tablets, when small amounts of data are recorded in random locations.

Most devices that can write HD video require a 10th class microSD memory card, but most MicroSD Class 10 cards are capable of more than the minimum speed in the record of 10 MB / s.

It is here that the UHS system comes into play. This means Ultra High Speed \u200b\u200b(Ultra High Speed), and the letter U is used to designate the class. The letter U is used. MicroSD UHS 1-class memory card writes with a minimum of 10 MB / s, while UHS 3 cards are recorded at a minimum speed of 30 MB / from.

You can also see UHS-I or UHS-II on the map. This suggests what technology is the micro SD memory card. The UHS-I "BUS" can operate at a speed of up to 104 MB / s, while the UHS-II bus can transmit data at a speed of up to 312 MB / s. This does not mean that the card will read and write at these speeds, these are peak indicators.

In order to benefit from higher speeds available to UHS-I or MicroSD UHS-II, you need a device that is compatible with this standard.

You can easily determine the UHS-II card, because it has a second number of contacts under the main set. All cards tested in this article have Class 10 or UHS-I.

SanDisk has shown the MWC 2016 in Shanghai what the manufacturer calls the world's fastest map of its MicroSD on 256 GB - SanDisk Extreme MicroSDXC UHS-I 256GB.

A new card uses a new speed classification system called Video Class. You will see this system on the maps in the near future, with a marker V. as in the original class system, it means the minimum sequential write speed in MB / C and ranges from V6 to V90.

Best cardsMicroSD 2018: temperature, x-ray and strength

MicroSD memory cards are small and easily lost, but in addition to buying a special cover for your collection card, it is important to choose memory cards that can experience the journey and any other factors that can jeopardize their functioning.

Some manufacturers argue that their cards are waterproof, as well as protected from X-ray. However, these characteristics are relevant for almost all MicroSD cards. The data is stored not on magnets, so the scanner at the airport should not create problems, as long as you are trying to read or write data to the non-waterproof car card reader, the microSD memory card must be able to relive the surface moisture.

Maps can also be an assessment of suitability at certain temperatures, say, from -25 to +85 degrees Celsius, resist shocks and concussions, as well as much more. As long as you are ready to pay more for one of these cards, you can qualify for guarantees if it suddenly fails, because it visited in an elevated temperature or "shook".

The warranty, therefore, is the most important among all these things: check not only the duration, but also the conditions that cover the warranty.

Best memory cardsMicroSD: What card to buy?

Our main recommendation is to adhere to well-known manufacturers who can provide a guarantee for their cards. Solid manufacturers include: Toshiba, Samsung, SanDisk, Lexar, Kingston, and Verbatim, among others.

There are many fakes and low-quality microSD, so make sure you buy from a reliable supplier. If you see a map on Avito, significantly cheaper than you expected, you should not hurry!

Before you buy a MicroSD memory card, check the maximum device power. Some mobile devices are limited to 32 GB of memory, as they are SDHC, and not SDXC. It is tempting to get a 128 GB card, but it simply will not work if the device cannot access it.

Quadcopters / Action Cameras

If you buy a MicroSD memory card for the purpose of writing 4K video, look for a UHS-I Class Map 3. Many also recommend the same cards to record Full HD (1080p) video, especially at a high frequency of frames.

Phones / Tablets

It is difficult to focus the buyer here using common characteristics, since these devices are based on the transfer rate of small files, and this is an important difference. We will consider more compliance with mobile devices in the reviews below.

Let's try to find out what class of the memory card should be equipped with your smartphone, tablet, laptop, camcorder or camera, when such a need arises, and what class of memory card is better for each of these devices?

To do this, consider in detail what now there is a classification of memory cards, and than one miniature storage device differs from the other.

Before you know what the cumulative class class means, the concept of information carrier speed should be clarified. There are two different values \u200b\u200bof this parameter: the first is the speed of reading or data transfer, and the second is the speed of data recording. The speed of reading is almost always the faster of recording speed, while it does not have a direct relationship to the class class: it may even be that the flash drive with the designation "class 4" will be read faster than the class 10 flash drive.

Of the two numbers describing the characteristics of the media, it will be a larger number: the higher the read speed, the easier and faster can be transferred to the external device. The recording speed is important for equipment performance, and it is it that allows you to record video in high-resolution format. Recognize, whether the manufacturer suggests a good high-speed mode, you can look at the reverse side of the packaging.

Since some unscrupulous manufacturers indicate their products overestimated characteristics, it is better to acquire memory cards of well-known brands, but, in any case, it is always possible to refine the speed data on their own. Check speed easily with special programs, such as USB-Flash-Banchmark and Check Flash, which can be downloaded for free or H2TestW utility.

Existing types of cards

Modern digital information carrier is of different sizes: mini, micro and full-length option, while the smallest dimensions are intended for a smartphone, a tablet or a mobile phone, and those that are larger, used in camcorders and cameras.

For a long time, the main carrier was CompactFlash, or CF cards, the size of 43 x 36 x 3.3 mm, and, although these formats have already passed, however, they are still used in some DVRs today.

The most common type of digital storage equipment is currently SD Card (Secure Digital Memory Card) or SD card.

This device not exceeding the sizes of the postage stamp, the dimensions of 32 x 24 x 2.1 mm, exceeded all the parameters of the CF card, and almost the entire modern technique with it is compatible. Devices of higher capacitance began to be denoted by an SDHC abbreviation, and ultra-high - SDXC.

Micro SD or micro SD card is just a miniature version of the SD card, sizes of 11 x 15x 1 mm, which is inserted into devices with limited space, such as phones. However, if necessary, it can be installed even in a laptop if you use the special adapter existing for this. There is also mini SD dimensions of 21.5 x 20 x 1.4 mm, since some types of equipment are equipped with such slots.

SD Card Cards

Suppose that we already know how much the cumulative device should be, what amount of its memory we need for optimal work. It remains only to find out what a memory card class is what this SD card parameter affects to select the necessary one. It is from this characteristic that will depend at what speed we will be able to transfer or receive information you are interested in.

So this is a parameter determining the degree of speed of the SD memory card by which all devices are divided into:

1. Class 2 - speed from 2 MB / s and up to 4 MB / s. Since the recording speed is very small, such a flash drive class should not be used in video cameras or digital cameras. Compensates the lack of speed relative low cost cards, so it can be safely used to play sound and images, that is, in audio or video players, since in this case you do not need high speed.
2. Class 4 - speed from 4 MB / s and above. For amateur home photography in digital cameras, you can use a four class. The fourth grade, in addition, is installed in the DVR and some inexpensive non-professional video cameras.
3. Class 6 - guaranteed speed from 6 MB / s and above. A flash drive of this level can already be installed in semi-professional video cameras and mirror cameras that are removed in RAW format. They allow you to get a fairly high picture quality.
4. Class 10 - speed ranges from 10 MB / s and above. A flash drive of the 10th grade can be equipped with auto registrar, professional video and photo equipment with Full HD recording. Class 10 allows you to produce serial photography, shoot in RAW format and save images, which is of great importance for professional photographers. However, such devices are somewhat more expensive, for example, the MicroSDHC Class 10 memory card will cost at least 1000 p.
5. SD Class 16 - speed of at least 16 MB / s, but it is still very difficult to buy this card in our country, because it has not yet come to a wide sale.
6. Ultra High Speed \u200b\u200b(UHS) - Such ultra-high speed maps can only be used with compatible devices, as usually written in the instructions. Class 10 UHS I is a high-speed card whose write speed can reach 50 MB / s or more.

There is a UHS specification, which regulates the speed of the equipment. According to the UHS-I standard, the rate of data exchange must be at least 50 MB / s and to 104 MB / s, according to the UHS-II standard - at least 156 MB / s and to 312 MB / s. CLASS 10 Map UHS I allows you to ensure the highest level of recording in real time and, in addition, get the large-sized video in HD format.

How to determine the class memory card? You just need to look at it carefully: the circle called the number is not the front of the digital media of the information and will be the desired value.

How to choose a flash drive

It should be borne in mind that the newest formats of memory devices may not approach outdated equipment. For example, if a smartphone supports Micro SD format, this does not mean that it will support and work high-speed Micro SDXC. Therefore, to find out this opportunity, it is better to familiarize yourself with the documentation for the smartphone.

Micro SD, as well as SD media, there are two formats (SDHC capacity up to 32 GB and SDXC with a capacity of 64 to 512 GB) and are used in all modern smartphones and tablets. The tenth class of such information media is no different from their full-size analogs. Thus, the higher the SDHC memory card classes, the more the data transfer occurs, which is the main advantage of those Micro SD cards, which are more expensive at the same capacity.

For example, a MicroSDHC Class 10 32GB memory card, worth about 1500 rubles. Ideal for modern digital devices, such as phones, camcorders, smartphones, pocket computers, audio players and gaming consoles. If you do not save on the class of equipment, pursuing a momentary benefit, you can get long-term excellent results in the future use of technology: high-quality pictures and stunning videos, as well as money from their sale.

The history of the development of SD cards has more than 10 years. During this period, the drives changed several generations, increased the maximum amount of memory, added in speed and became commonplace for the ordinary user of technology. Let's figure out what the SDHC memory cards differ from SDXC and SD. We also figure out in their characteristics and how to choose a suitable drive for your device.

SD drives differ from SDHC and SDXC.

The SD abbreviation is decrypted by Secure Memory Card. This type of media is manufactured since 1999. Of course, in primeval form, no one uses cards for today's reasons. Over time, the creators began to increase the characteristics and volume, the release of new generations, which will be discussed below.

The main difference, as mentioned above is the capacity. However, devices also differ in read / write speed and support in different devices (cameras, phones, and so on). There are 3 types in total:

• SD HIGH CAPACITY;

Let's look at the differences of the SD, SDHC and SDXC memory cards in all characteristics separately.

Difference in volume

The oldest and unclaimed type is microSD. The first generation accommodates only 2 GB of information (version 1.0) and up to 4 GB in version 1.1. These figures are currently extremely small for the modern consumer, given the size of high-quality videos and photographs that give new smartphones and cameras. Such a carrier can be useful only to transfer small files. Specially acquire such a carrier does not make sense. The role of the file system uses FAT16.

Second Type - SDHC Cards. Different from ordinary SD increased space and file system. Now the maximum capacity is up to 32 GB, the FAT32 file system is used.

The most modern view is SD Extended Capacity. The standard was issued officially in 2009 and remains demanded to this day. Compared to the previous generation, the SDXC standard, characterized by the volume, can accommodate up to 2 TB of information. File system - EXFAT with formatting support in FAT32.

Now you know the main difference between the SDHC memory cards from the SDXC, which is worth paying attention to when choosing a drive for its device.

Support for devices and operating systems

At the time of 2017, the SD generation is supported by all devices that have an appropriate slot. All devices that support only the SD standard will not be able to read information from HC or XC media. Cameras and smartphones with SD Extended Capacity are compatible with all three generations. No backward compatibility.

Although the SD from High Capacity and Extended Capacity may also support operating systems:

• due to EXFAT, SDXC drives are not supported by the Windows XP operating system without installing a special update;
• MacBook and Mac OS has SD Extended Capacity support from 2011;
• flagship devices on Android support SD Extended Capacity. For all other smartphones and tablets, you will need a special driver from Samsung.

Difference Micro and Mini

Now we'll figure out what the microSD memory cards differ from their mini analogs. As you can guess, the main difference lies in size. For compact techniques, a mini version is created, which is usually supported in smartphones (it is customary to install the second SIM card slot). The difference in MicroSDHC, SDXC and SD is that they are connected to the card reader without an adapter, and the MINI version requires an adapter.

Speed \u200b\u200bdifference

Now we will analyze the differences between all SD, SDHC, SDXC memory cards for information reading speed. High-speed classes are marked on the housing of each drive: 2 (from 2 MB / s), 4 (from 4 MB / s), 6 (from 6 MB / s), 10 (from 10 MB / s). In the designation of the classes, the minimum value of the recording rate is indicated, so in practice, the indicators of a separate drive may be higher. Manufacturers indicate the characteristics in MB / s, and not according to the established classification. Also SDHC and SDXC can support Ultra High Speed \u200b\u200btechnology (up to 25 MB / s).

When choosing a drive, pay attention to its type and volume. Actual today are SDHC and SDXC. Also before buying, check compatibility with the device for which the carrier is purchased to avoid incompatibility.

Often users interested in Microsdhc memory card: what is different from microSD and microSDXC. Secure Digital Memory devices are widely used as additional storage devices on portable devices, such as tablet computers, mobile phones, digital cameras and GPS navigation devices. SD, SDHC and SDXC drives are protected digital memory cards, but they have certain differences, the understanding of which is necessary to ensure optimal performance of portable devices.

If the user is interested in what is the difference between the types of flash drives, it will be interesting for him to find out that the SD memory card is the first generation of Secure Digital, which was designed to improve the MMC standard (Multimediacard). SD drives were created mainly in order to increase the storage space of files on mobile phones. The MMC standard is also used to store data. It looks like a microsphere, but is considered obsolete, because it cannot provide a sufficiently high speed of information transfer.

Those who are wondering than the microSD memory cards differ from MicroSDHC, it will be useful to know that the presture of the ordinary SD cannot exceed 2 GB. As a rule, it has a standard physical size of 11 mm x 15 mm. The maximum reading and recording speed for such a drive is 25 Mbps. This is a very decent speed if you take into account the small physical size of the device. This card is mainly used on mobile phones for storing photos, video recordings and apps. SDHC and SDXC drives appeared later.

Second and third generation SD

SDHC

The SDHC SDHC (Secure Digital High Capacity) differs from the usual microSD more roomy information storage, the size of which can be from 4 to 32 GB. It is also a protected digital device with a standard size of 11 mm x 15 mm. The difference between SD from the SDHC consists in a higher data transfer rate (the Secure Digital High Capacity can be from 50 Mbps to 150 Mbps).

SDHC memory cards are largely identical to SD drives, but there are significant differences. Old devices for SD cards are incompatible with SDHC, because the latter use FAT32 file system instead of FAT12, FAT16 and FAT16B. The difference between MicroSD and Microsdhc is that the latter uses a more convenient file system. However, some of the outdated gadgets can still use the Secure Digital High Capacity Standard after updating the firmware. Devices that are originally designed for SDHC must recognize conventional SDs without problems. Prices for such drives may vary depending on the amount of memory.

SDXC.

The SDXC (Secure Digital Extended Capacity) may have a volume of 32 GB to 2 TB and this is the main difference of SDHC memory cards from SDXC. As with other similar drives, the physical size is 11 mm x 15 mm. Data transfer rate may vary from 50 to 312 Mbps. The speed potential of such a drive depends on the version of its design. Build 3.0 with UHS-1 bus (Ultra High Speed) can accelerate up to 104 Mbps, and the more recent version 4.0 with UHS-2 reaches 312 Mbps. Prices for similar drives can vary greatly depending on their volume and speed. MicroSDHC and MicroSD devices in many countries are already considered outdated standards. Nevertheless, the SD and SDHC memory card are still popular.
