The memory capacity of modern smartphones has increased greatly in recent years and in the case of flagships it already reaches 128 or even 256 GB. This is more than enough for most users, but sometimes this is not enough, and what can we say about state employees, who often have no more than 64 GB. The solution to this situation is the best memory cards for smartphones, which can be used to store photos, videos, music and other files you need. They were selected for the rating based on user reviews and expert opinions.
SanDisk Ultra microSDHC Class 10 UHS-I 80MB/s
A tenth class memory card has a guaranteed minimum write speed of 10 MB/s, and file reading is carried out at speeds of up to 48 MB/s. The flash drive is suitable for recording FullHD video, serial photography, or running various programs. SanDisk Ultra microSDHC Class 10 is housed in a shockproof and waterproof case that is resistant to vibration, radiation and temperature fluctuations. Thanks to this, you don’t have to worry about the safety of all data stored on the device. The drive will remain operational even if the gadget in which it was installed breaks down.
Memory size
The file size of a movie in DVD quality with a resolution of 1920×1080 pixels can reach 9.5 GB. A flash drive with a memory capacity of 32 GB will fit no more than 3 of these films. Drives larger than 64 GB are expensive and are only supported by newer phone models.
The solution is to search for films in lower quality or HD 720p resolution. Such files take up 2-3 times less space. For example, a 60-minute episode in WEB-DLRip format, designed for streaming video, is 947 MB. This will allow you to collect a whole season or half of it on one 32 GB flash drive at once.
The table provides information about the approximate number of photos and audiobooks included on drives of different sizes.
And in this table, the manufacturer reports how much memory is actually available to the user.
| Size, GB | Really available, GB |
| 4 | 3,6 |
| 8 | 7,2 |
| 16 | 14,4 |
| 32 | 28,8 |
The ideal size of a flash drive for a smartphone today, from the point of view of the maximum ratio of capabilities and price, is 32 GB. It's inexpensive and comes with a lot.
Samsung microSDHC EVO Plus 95MB/s
Samsung microSDHC EVO Plus is a good choice for taking photos, recording 4K video, and quickly interacting with large amounts of data. Compact dimensions open up the possibility of use in any phone and video camera. The kit includes an SD adapter that expands the scope of application. Read speed reaches up to 95 MB/s, but writing is slow - 20 MB/s. It will not drop below 10 Mb/s under any conditions, as stated by its compliance with UHS I Class 1, V10 and Class 10.
The manufacturer uses advanced protection technologies - from water (withstands immersion in sea water for up to 72 hours), high and low temperatures, electromagnetic and x-ray radiation. But a flash drive will not fit into the DVR, as well as into other systems where data is continuously recorded. This is the only thing the model cannot handle.

Transcend TS*USD300S-A
A memory card allows you to increase the storage capacity of your phone or tablet, which can be used to store any files. Only reliable and proven materials were used to manufacture the model, thanks to which it will delight you with impeccable functioning for many years. Its volume is small - only 16 GB, but it is very cheap. The recording speed reaches 45 MB/s, which makes the drive suitable for recording FullHD video. Reading speed - 95 MB/s.
Option to connect a flash drive to your phone
If you have a regular flash drive with a standard full-size USB, then you can buy a special OTG cable.
On one side of this wire there is a socket for a standard USB, and on the other - a MicroUSB for mobile gadgets.
Attention! Most Android phones released in the last 3-5 years support OTG mode. In older models, this option for connecting an external drive may not work correctly.
The second option is to buy a flash drive with two USB connectors.
The figure shows one of the design options with a rotary connector block. And here is another option with a retractable connector.
In particular, owners of the Xiaomi MI4C smartphone, which is equipped with a Type C socket, can do this. A standard OTG cable will not work for such gadgets.
Kingston SDCS2/*SP
Speaking about the best Micro SD cards for a smartphone, we should mention Kingston SDCS2/*SP - an inexpensive but reliable model, created taking into account the features of the Android operating system. The storage capacity is 64 GB, which is enough to store a variety of content, but the performance class is only A1, which is inferior to A2 in terms of application loading speed.
The device is suitable for recording video in FullHD and storing a large number of photos. In read mode we get a speed of 100 MB/s. The manufacturer provides a lifetime warranty for its product, which already says a lot about its reliability.

Types of memory cards
Types of cards
Memory cards for phones are available primarily in three formats:
- SD cards are a classic option with a standard size of 24 by 32 mm.
- MicroSD is no less common option than the previous one, measuring 11x15 mm.
- CompactFlash is an outdated version of 42x36 mm.
Important! The latter format is not used practically anywhere except photography. Many experienced photographers prefer CompactFlash, considering it the most reliable and proven of all.
Some companies work only with their own media formats. For example, Sony supports its own development - Memory Stick. It is only compatible with branded devices. The storage will not work on other gadgets.
What is the difference between micro SDHC and SDXC
The difference between SDHC and SDXC
Some of the most common formats among users are:
- microSDHC;
- SDXC.
But not all buyers understand how they differ from each other and which one to buy for their gadget.
Technologies are developing rapidly and the once very popular microSD has been replaced by the new micro SDHC format. The dimensions of the drive remained unchanged, but the characteristics have improved significantly:
- memory expansion up to 32 GB;
- high read and write speed (50-150 MB/s).
It’s convenient that flash drives and card readers have good backward compatibility. But the microSD reader will not be able to recognize the micro SDHC.
Another new format is microSDXC drives. They are also no different from previous options in terms of dimensions. But they are more advanced in technical properties:
- exFAT file system;
- memory capacity up to 2 TB;
- read speed 50-312 MB/s.
Interestingly, readers designed for this format successfully recognize previous versions.
To summarize, we can conclude that microSDXC is a more advanced storage option with exFAT formatting. And it should be considered by those who need a large volume and quick reading of various types of information.
Kingston SDCS2
Micro SD is suitable for use in Android phones and corresponds to performance class A1. Its potential is enough for shooting high-resolution photos and recording FullHD video. Reading speed reaches 100 MB/s. The manufacturer gives a lifetime warranty on its device, and thanks to its significant capacity of 128Gb, it is suitable for storing a large amount of data. The package includes an SD adapter, which expands the scope of application.
The best inexpensive microSD memory cards
Mirex microSD Class 4 2GB
The price of this card is its main and, perhaps, only real advantage. It costs less than 200 rubles. For a low price, you will have to pay for a small volume - only 2 gigabytes - and low speed - 12 MB/s for reading and 5 MB/s for writing. It is better not to use this card in SLR cameras, but it is compatible even with the oldest phones and players. So if you decide to expand the available memory of some rare gadget, this card is for you.

Qumo MicroSD 2Gb + SD adapter
This microSD card is the price record holder in our selection: it costs only 200 rubles. For this money you will get 2 gigabytes of built-in memory and an adapter for full-format SD. The manufacturer decided not to disclose the technical parameters of speed and data reading, and the speed class is also not indicated anywhere, so you shouldn’t expect any achievements from this device. Similar to the previous card - a good budget solution for obsolete, but still beloved electronics.

Western Digital WD Purple
Western Digital WD Purple is highly reliable and suitable for continuous recording in DVRs and smart security cameras. The card is based on 3D NAND flash memory technology, which remains operational at temperatures from -25 to +85 degrees. Other influences are also not dangerous - moisture, X-rays, magnetic fields and shocks. Read speed is 100 MB/s, write speed is 65 MB/s.
Rating of flash drives for cameras
Professional photographers know which memory cards are best to buy for their cameras. The main requirements for these media are capacity and speed. Firstly, all videos and photos taken in one session must fit on the card. Secondly, shooting in bursts, especially in RAW, should not overflow the buffer, so that unique frames are not lost - this is also important for UHD clips, so as not to get a mosaic on the screen.

The rating of memory cards is completed by microsd from South Korea, produced in capacities of 64, 128 and 256 GB. Red and white plates for reading on a computer are placed in the included adapter.
The manufacturer claims that the media can show 100 MB/sec for reading and 90 MB/sec for writing - in addition to the traditional C10 grade, they are compatible with the UHS-I U3 bus.
The actual figures are somewhat lower - 88 MB/sec for reading and 64 MB/sec for writing, but this is enough for UHD videos and shooting in RAW.
Choosing a good microSD: tips and tricks
Choosing a flash drive in 2022 is not so difficult:
- 90% of smartphones require microSD memory;
- Amateur cameras, surveillance cameras - standard SD card.
Professional photographers should check the instructions to see if it says Compact Flash or something exotic.
Speed is becoming increasingly important, but grade 10 is almost always sufficient.
The volume should be chosen on the principle of reasonable sufficiency - 512 GB, of course, is cool, but it is still very expensive, and there is nothing special to fill such storage with.
SanDisk Extreme microSDXC Class 10 UHS Class 3 V30 A2 160MB/s
Modern MicroSD complies with the A2 standard, designed to improve mobile gaming performance, making it an excellent choice for phones from any manufacturer. It loads programs that perform a large number of read and write operations faster. It copes equally well with recording video in 4K, which is facilitated by good speed characteristics.
The manufacturer claims a read speed of 160 MB/s, when in reality it is close to 100 MB/s. Recording speed - 90 Mb/s. The product complies with the UHS-I U3 and V30 specification, which means the recording speed cannot be lower than 30 MB/s. The device is housed in a waterproof case and comes complete with an SD adapter. Along with it, you get the opportunity to use proprietary software for backing up data on Android - Memory Zone and for recovering lost files - RescuePro.
Which company is better?
There are many different brands on the electronics market. Below are the best flash card manufacturers.
Kingston
An organization from America was formed not so long ago - in 1987. In the first couple of its existence, the company was designing reliable SIMM memory blocks. After some time, the company became one of the most popular manufacturers of permanent and random access memory.
In general, today you can easily find SSD drives, USB drives and high-performance flash drives in retail store windows. All new products are pleasing with their almost absolute compatibility with the established speed standard, as well as their long service life.
Samsung
It’s hard to believe, but today this brand is the most active in designing ultra-fast flash drives. Most likely, in a few years, flash drives of this particular brand will become the highest speed. This is proven by the fact that in the company’s advanced smartphones with memory characteristics, everything is excellent. In terms of speed, it outperforms all similar components made by other manufacturers.
It is worth noting that innovative drives will be made using similar technology, which is why their speed parameters will remain at an excellent level. But don’t forget that the products of this brand are not always budget-friendly in price.
SanDisk
Another US company that produces solid-state memory. Its drives are considered the most wear-resistant. At the same time, the company does not forget about less popular flash drive formats.
For example, to this day they produce cards that are necessary for the functional operation of the PSP Portable and some other Sony brand products. It is worth noting that SanDisk is not a self-sufficient company. Today it is “under the wing” of Western Digital (a popular hard disk manufacturing company).
Sony
The Japanese brand is trying to stay on the cutting edge of innovative technology in the electronics industry. She immediately began making cameras as soon as the digital format appeared. Its game consoles were the first to abandon the cartridges that were common at that time.
Regarding flash drives, the company is distinguished by good quality and compatibility with most electronic equipment. The company has only one drawback - the cost of its products, which is why Sony drives are sold at a much higher price when compared to other specialized companies.
Transcend
Like the other manufacturers discussed above, Transcend was opened in the late 80s. Its main department is located in the Chinese Republic of Taipei.
For some time, this brand was producing digital players and other multimedia gadgets. But today he is engaged in the manufacture of flash drives and the devices needed to read them - card readers.
Products of this brand are inexpensive, have fairly good speed capabilities and wear resistance.
SanDisk Extreme Pro microSDXC Class 10 UHS Class 3 V30 A2 170MB/s
The flash drive meets the following speed standards - general C10, UHS class U3 and video recording speed V30. Another important point is that the memory card complies with the A2 standard, which is necessary for interacting with mobile games and applications. Linear read speeds reach 170 MB/s and write speeds up to 90 MB/s, making the SanDisk Extreme Pro microSDXC Class 10 UHS one of the fastest MicroSDs on the market.
True, this is only according to the manufacturer’s statements. Real testing showed different results - the read speed was slightly less than 100 MB/s. This is due to the cunning of the manufacturer, who indicated on its official website that the speed will be the same only when used in a DVR, smartphone or other equipment of the corresponding class. Even despite this, the flash drive is one of the fastest at the moment. It is resistant to any impact and is suitable for any use scenario, including as a drive for an action camera.

SanDisk Extreme microSDXC Class 10 UHS Class 3 V30 A2 160MB/s.
Photo: SanDisk An advanced memory card from SanDisk, the same company that was at the forefront of creating the SD standard. The 64 GB card stands out among its competitors due to its price - a conventional gigabyte of memory will cost more here than many others. The so-called “golden series” gives an advantage in reading speed - 160 MB/s. The recording here is stated at 90 MB/s. By the way, this is enough for comfortable work with 4K video with an average bitrate, but it could be more. Fans of shooting video will also like the declared speed class UHS 3. The card has a lifetime warranty, but keep in mind that if the Extreme fails, you will most likely have to directly negotiate a replacement with the official representative office in Moscow.
Advantages and disadvantages
UHS 3, fast reading
Somewhat overpriced, although the warranty is lifetime, it’s not very convenient

Western Digital WD Purple.
Photo: Western Digital The impressive-looking card attracts attention with its purple color. We know Western Digital more as a manufacturer of hard drives, but they also make flash drives. Here, a gigabyte of memory will cost even more than the previous model. The card claims UHS 3 speed class with 100 MB/s read and 60 MB/s write. The last figure will not be very inspiring, for example, for videographers shooting material in 4K 10-bit. But the stated speed is fair. In addition, the card has good survivability - users practically never encounter memory failures.
Advantages and disadvantages
Excellent quality, no glitches when recording
Recording speed could be higher

Transcend TS*USD300S-A.
Photo: Transcend This model is, as they say, folk. A 32 GB card can be bought for 800 rubles, and if you look for it, it’s even cheaper. The stated read speed is 95 MB/s, but the write speed is only 45 MB/s. This means that it will be difficult to record video even in FHD with a “fat” bitrate on this card. But that’s okay, the problem with the TS*USD300S-A lies elsewhere. The manufacturer in this model clearly saves on chip rejection, so how long a particular instance will live is a lottery. For some, the card works every day in a car recorder for more than the five-year warranty, while others complain that their smartphone fails after a month and a half. So don’t rush to throw away the packaging and receipt.
Advantages and disadvantages
Inexpensive, good performance in its price range
Unstable quality

What other memory cards are worth paying attention to?
Kingston SDCR (average price 800 rubles)
Kingston SDCR.
Photo: Kingston A relatively inexpensive but fast memory card from the famous flash memory manufacturer Kingston. There is support for UHS-I and VSC. The last three letters mean that the card is optimized for recording video in resolutions up to 8K at speeds up to 90 MB/s. In fact, the recording ceiling for this card, as the manufacturer honestly states, is 70 MB/s, which is also not bad. Read speed is maintained at 100 MB/s. But there are nuances. for example, some users complain that the card gets very hot during recording. It is possible that frequent cases of failure are associated with overheating. Please note that the warranty period here is only 1 year, which is much less than that of its main competitors.
Advantages and disadvantages
Good write speed, VSC certified
Gets hot, short warranty
Silicon Power ELITE microSDXC UHS Class 1 Class 10 (average price 700 rubles)
Silicon Power ELITE microSDXC UHS Class 1 Class 10. Photo: Silicon Power
What are we all about the recognized giants of the memory card market? Maybe look at the second echelon? For example, this 64 GB card from Silicon Power sells for 600-700 rubles. Tempting? Yes, but the write speed here is only 15 MB/s. And this immediately puts an end to any attempts to write a video on it. No, the card will cope with simple video recorders and smartphone videos for Instagram. But it’s better to use it to consume ready-made content. For example, watching a series on a tablet - reading here is at a decent 85 MB/s. Surprisingly, the card is quite reliable; defects are rare here. Well, if you are still unlucky, there is a five-year warranty.
Advantages and disadvantages
Affordable price, five-year warranty
Not suitable for video recording

Photo: Sony Almost 2 thousand rubles is not cheap for a 64 GB memory card. But “Sonyboys” are well aware that if you want Sony, you have to pay. Let’s say right away that this model is quite old and has been on the market for several years without changes. Its actual write speed is unlikely to be higher than 20 MB/s. Reading is 90 MB/s, which hints at the area of application of this memory card. There are no complaints about the reliability of the card, but the year of warranty is alarming. For such a price, the Japanese could have been more gallant with their customers.
Advantages and disadvantages

It may seem that three thousand rubles for a 64 GB memory card is a robbery. But ADATA Premier ONE is made according to the UHS-II speed standard. If your gadget is compatible with it, for example, it is a professional mirrorless camera, then the recording will reach 155 MB/s, which is very, very high. Reading is generally 275 MB/s, which is at the level of SSD drives. Therefore, when choosing such a card, you need to understand for what purpose it is needed and what device it will work with.
Advantages and disadvantages
Huge write and read speed, cheaper than direct competitors
You have to pay for record speed

Another budget item in the ranking of the best memory cards. A card with a capacity of 64 GB can be bought for 680 rubles, which is interesting. The manufacturer claims that the write speed is 45 and the read speed is 95 MB/s. If the second figure still inspires confidence, then the first is embellished by 15-20%. UHS Class 3 seems to guarantee sane operation with 4K video recording, but this model has its own nuances. Some users complain that the card refuses to record new data after two or three months of use in the DVR. Well, at least a five-year warranty will help.
Advantages and disadvantages
Cheap, five years warranty

The card is not very fast - the read speed is 90 MB/s, and the write speed barely reaches 30. Moreover, the latter is not yet accelerated to this mark on all devices. It's funny that the manufacturer claims shock resistance and water resistance - any memory card of the slightest quality is not afraid of falling or splashing water. However, there are no complaints about this Toshiba - everything is reliable and predictable. And if something goes wrong, there is a five-year warranty.

The actual read speed of this card, which does support UHS Class 1, falls slightly short of 90 MB/s. Of course, the bottleneck is the write speed - only 25 MB/s. And be prepared for the random quality of the card - there are complaints about the instant death of the “patient” after a couple of months of easy work.

Kingston SDCG3
The drive has a capacity of 64 GB, which, according to the passport data, gives a read speed of 170 MB/s and a write speed of 70 MB/s.

How to choose a good MicroSD memory card for your phone?
First of all, you need to pay attention to its volume. The more, the better, but you need to take into account other characteristics on which comfort and usability depend. These include size, speed class, compatibility with various devices. Thus, not all flash drives are suitable for continuous video recording, which is needed in car DVRs and video surveillance systems.
SD cards are suitable for cameras, camcorders, quadcopters and laptops, but you can also install MicroSD in them. An adapter is designed for this, which is usually included in the package. On sale you can find drives with capacities from 2 to 512 GB. But you need to take into account not only this, but also the maximum storage capacity supported by your smartphone.
Choose the right speed class:
- The second is up to 2 Mb/s. Its purchase should be avoided;
- Grade 4 or 6 will be a good choice for everyday use;
- Class 10 cards are suitable for RAW photos and 4K video;
- Professional operators and photographers prefer MicroSDs corresponding to the UHS-I and UHS-II speed classes. The A2 standard speeds up the launch of applications from a flash drive.
Our rating will help you choose the best MicroSD, but you need to start based on the tasks that you assign to it. If you plan to record video and take photos in high resolution, then give preference to drives with speed class 10.

How to choose a memory card for your phone: important criteria
How to choose the most reliable memory card
Everyone chooses a medium for their own purposes, but in any case it is important to consider the basic parameters listed below.
Manufacturer
A brand in this segment is not just a name, but a guarantee of quality. Well-known companies supply the market with memory cards that do not break the first time they are used. And if a defect is discovered, the product will be replaced under warranty.
Budget firms do not provide such conditions. Therefore, savings can result in the loss of important information and the need to urgently look for a new medium. As a result, costs will increase significantly.
Important! If you don't want to pay the highest price for media, choose it from the middle price category. Such devices usually have all the advantages of expensive models, but are sold at a lower cost.
Format
Here you need to rely on the technical device for which the memory card is purchased. The most common formats are:
- SD;
- microSD
They are used primarily in video and photographic equipment. They are convenient to change, although the size often causes some inconvenience.
MicroSD cards are selected for smartphones. They are perfectly compatible with regular SD, but only if you have an adapter. Those looking for a card for a tablet should also consider microSD.
Important! There are also non-standard options on sale. They are designed for certain types of devices and have no analogues. Therefore, be careful when going to the store to buy a flash drive.
Class
The classes reflect the speed at which information from the media will be reproduced. The class designation is equivalent to the speed in Mb/s. For example, class 2 is recording data at a speed of 2 Mb/s, class 3 is 3 Mb/s.
Modern devices have faster speeds. Therefore, an updated class standard has emerged - UHS:
- 1 – 10 Mb/s;
- 2 – 2 Mb/s;
- 3 – 3 Mb/s and so on.
Often both options are indicated on the packaging.
Volume
This is one of the most important and at the same time subjective parameters. Many people purchase memory cards in order to permanently store a large amount of data on them. Others transfer information to a flash drive from time to time and do not use it to store files on a regular basis.
When choosing an SD format option, focus on the following indicators:
- standard SD holds only up to 2 GB;
- SDHC – memory card up to 32 GB for tablets and phones;
- SDXC – saving up to 2 TB of information.
Data writing and reading speed
This criterion reflects how quickly information:
- sign up;
- will be played from the flash drive.
These indicators are most important for video cameras and cameras, but smartphone owners also pay attention to them.
Important! The higher the speed, the more expensive the media. Therefore, proceed purely from your own needs and do not take an expensive option if there is no direct need for it.
