Adata Premier MicroSDHC
We recommend this memory card if you are interested in a device with good resistance to cold, heat, X-rays and water, and the large storage capacity is not necessarily a necessity for you. It is a microSDHC / SDXC UHS-I class 10 model, which means that it constantly exceeds the transfer speed of 10mb / s.

It is not the most powerful microSDHC card on the market, but you can buy it at a reasonable price and it offers you a pretty good storage capacity. For more, you can turn to the 64GB model, also available in this series.
128 GB memory card:
Samsung Micro-SDHC EVO Plus
When choosing a device with a larger capacity, such as this memory card, 128 GB, first of all you have to make sure that the device you want to use it accepts such a high value. It is of the small type, but it also has an adapter for the normal version.
Regarding the speed with which the data is written / read, this model is part of Class 10, UHS 3, which is why it will offer transfer speeds of about 100 MB / s. You can also use it to record it in 4K format, in case you are a professional photographer, vlogger and so on.
The card now in question is resistant to water (IEC 60592 and IPX7), but also to magnetic radiation and radiology, so that it can be easily used in any environment. Considering the capacity of this model, but also other features that we mentioned, the quality-price ratio is correct.
8 GB memory card:
Don’t have a very big budget and you need a cheap and good memory card? This could be a good option for you. You can use it for extra space on your smartphone, tablet, camera, MP3, etc., as long as a very large capacity is needed.
This 8 GB memory card is microSDHC time, with a write transfer speed of 10 MB / s. It’s not much, but it’s enough for the basics. In the event that you want to use it for devices that need a normal model, then you have an SD adapter included in the purchase package.
There are no details in the online environment regarding the resistance of this article to various external factors. We do not recommend this product to people who want, for example, to use it for high resolution filming. It does not come with a mini card adapter, but only with the micro and the normal version.
Micro SD memory card:
Sandisk microSDXC Ultra
This is one of the best memory cards. It is in microSDXC format and can be used on all kinds of devices, from smart mobile phones, to professional cameras that shoot in Full HD or 4K format. It will give you enough space for everything you want to save / record, because it has a very large capacity of 200 GB.
The card we are talking about now will allow data transfer at a very good speed, of about 100 MB / s, which is appreciated even by the most demanding buyers. It is part of the speed class 10 and the UHS-I U1 standard.
This micro SD memory card comes with an SD adapter that allows you to use such variants. From the point of view of the acquisition cost, it requires a slightly higher financial investment, compared to other items on our list, but it is worth the money, considering the ones mentioned above.
SD memory card:
Sandisk Extreme PRO
Sandisk Extreme PRO is considered by many to be the best memory card. We tell you from the start that it has a much higher price than other variants that have the same capacity as it, 64 GB. But this is a justified one. Why? We will tell you in the following.
The device is the first high-capacity device in the world, which supports VPG-655, more precisely, which ensures smooth, unblocked shooting in 4K format. In addition, it has much higher transfer speeds than you usually find on the market – 160 MB / s for reading and 150 MB / s for writing.
This is not an ordinary SD memory card, but one with the UDMA 7 (Ultra Direct Memory Access 7) interface, found in professional cameras. Not suitable for mobile phones or devices that support the popular micro / mini variants. It has no adapter but is easily delivered.
Advanced Memory cards Buying guide
Many times, we may run out of space on our phone, tablet, camera, etc. In such cases, the saving solution is to use a memory card that allows you to write data and to help you expand the capacity of the device to be able to keep as many pictures, videos, audio files and so on. Such products are often sought after by those who have devices with very low memory – drones, car cameras, thermal imaging cameras, etc.
But you can’t buy the first model that comes your way, but you have to buy the right one. By what criteria do you choose it? We will tell you in the following.
Compatibility : This is the most important aspect, because if you do not choose the right item, you buy it in vain. Here we refer more precisely to the type of card that your device supports and to its maximum capacity. You will find such information in the user manual of the device in which you want to insert the card.
Capacity : Since you have established which model supports your item and the maximum capacity it can have, you need to think about how many GB are needed. Yes, you can use a 128 GB card, but you need so much, since you are a basic user, who still takes a picture from time to time or receives all sorts of files from friends on the applications socializing?
Then, if, for example, you are a professional photographer and you make content at a very good quality, will 64 GB be enough for you or is something much more necessary, such as a 256 GB article? Or maybe even 1 TB?
Think carefully about the needs you have and buy according to this criterion. The more storage a card gives you, the higher its price will be.
Tip : As you may have noticed, not all products in this category are the same. The difference is made between the physical dimensions (normal, mini or micro – SD / SDHC / SDXC) and those related to capacity.
In terms of size, they are normal (micro or mixed) memory cards (at good prices). The last ones are used together with an adapter that allows the introduction of the micro / mini ones in a special hole that transforms them into normal variants.
If you are interested in exactly what dimensions each has: normal – 32 x 24 mm, mini – 21.5 x 20 mm, micro – 11 x 15 mm.
Regarding the capacity, for SD / miniSD / microSD models, this is between 1MB and 4 GB. They are a bit older, which are no longer extremely desirable, but for many they are still good enough. Then follow the SDHC / microSDHC variants, which have from 4 to 32 GB and the SDXC ones that can reach even 2 TB. The latter are harder to find in our country, here the largest variants being 256 GB.
Speed : This detail is important, especially when you want what you copy to / from the card to transfer as quickly as possible. Until recently there were four speeds, numbered with 2, 4, 6 and 10, each digit representing the minimum number of MB / s with which the data transfer is made.
Over time, however, things have advanced and more high-performance devices have appeared (used in Full HD or 4K filming) and, implicitly, the need for higher speed. Thus, other upper classes were launched, among which we mention:
UHS (Ultra High Speed) – you can easily recognize it when you see such a model, because on it there is a symbol that resembles the letter “U”, inside which is passed a number from 1 to 3 (1 represents a minimum of 10 MB / s, 2 means at most 20 MB / s and 3 refers to at least 30 MB / s).
Video speed class – on some models you will see that certain values are entered in “Vx” format, where “x” is 6, 10, 30, 60, 90 and means the minimum number of MB / s with which data can be written on card. There are more expensive and helpful options for those who want to shoot at a 4K resolution.
Key details : Some models come bundled with a number of functions / features that make them usable and safer:
Recovery software – in case you accidentally deleted / lost various files, they can be easily recovered.
Increased resistance – is given by the ability of a device to withstand water, mechanical shocks, extreme temperatures, magnetic fields, etc., without damaging the data written on it.
Now that you have learned how to make an informed choice about such a product, it will be easier for you to form opinions about the best memory cards. Consider buying online, because you will find better prices and you will also save time, because you no longer walk through stores.
Does the brand or storage space matter more to a memory card?
When you want to buy a memory card, at a good price, brand and capacity are two important selection criteria.
The brand is important especially when you want something with a very large storage space, because not all manufacturers are appreciated for the quality of devices in such situations.
But capacity seems to be even more important, and here two aspects come to mind: compatibility and enough space. Regarding the first, check not to buy a model that allows more GB than it accepts the device in which you want to insert it.
Regarding the second point, you have to have room for everything you need and not exaggerate in the idea that “it’s good to be”, because the more generous an article is, the more expensive it is.
Who are the most popular manufacturers of memory cards for your phone?
If your budget is smaller, we recommend models from Sandisk, Transcend or Kingston. If you are not interested in the price, but the quality, opt for variants from Lexar, Toshiba or Samsung.
What memory card copy instructions should I follow?
Such an accessory is easy to use. Since you have it in a certain device, you can move multimedia files from the internal memory to that of the card, acting on the picture / clip / song you want transferred. We can’t say exactly the steps, because it’s different from one device to another.
Copying can also be done from the computer. In such situations, all you have to do is connect the device in which the card is located, via a wire or modern technologies (Bluetooth, for example), then select the desired file, and copy / move it to outer space.
Be careful not to disconnect the gadget during copying and have enough space on the card for what you want to transfer.
How to do data recovery from micro SD memory card?
If you have unpleasant situations in which you cannot access a card or you accidentally deleted the content from it, you should know that recovery programs are very useful – DiskDigger, ZAR X, Recuva or GetDataBack. These softwares will help you regain possession of lost files. They have a simple and intuitive interface, so it will not be difficult at all.
How to configure and use the memory card
It doesn’t matter if you buy memory cards, cheap and good or very expensive. You need to know how to configure and use them, so that everything is fine and you do not have unpleasant situations in which you do not have access to certain multimedia files. The tips below will help you.
Install the card
For starters, all you have to do is insert the card properly into the hole provided. This is done when the gadget is turned off. Look carefully at the tray in which you need to place it and position it correctly.
After you have done this, open the device. Most of the time, the settings are made automatically, without you having to do anything specific. If this does not happen, a notification will be displayed on the screen asking you to configure it, at which point you must follow the instructions received.
You may be asked if you want portable or internal storage. In the case of the first variant, when you insert the card in another gadget, what you have on it will be displayed (except for applications), and in the second it will not happen, but it will be necessary to format when changing his in another device.
Move files / applications to the card
Since you bought such a product, you most likely needed it. Well, see what you can transfer to it from the internal memory and do that. Such actions will lead to the release of internal storage space, which will lead to a better functioning of the operating system you use on a certain gadget.
There are cases in which certain phone models do not allow moving applications. In such cases, you can only transfer photos, videos and music.
If it is possible to transfer applications, keep in mind that once they are moved to the card they will be a bit slower. Ideally, you should do this with the ones you do not use daily.
Format it when you think something is wrong
In the event that you think there are problems with your memory card and you are afraid of losing what you have on it, transfer that data to an external device, then format it.
If you use it on your phone, you can do this from the menu, looking for the device and acting on it, and if you need to format it from your PC, for example, right click on it, selectFormat – Restore default settings – Start .
Once you have connected it to an external device, turn it off correctly
You will also have to be careful when you want to remove a card from your phone / tablet / camera, etc., but also after you have copied files from a PC.
Regarding the cases in which you want to physically remove it from certain devices, this must be done first from the menu. Go to the gadget settings and look for the option to remove / remove it (if it exists), then turn off the device and remove it.
If you connected it to a computer, before disconnecting it, right-click on it andRemove / Eject . By doing so, you do not risk accidentally losing data from the card.
Consider the above and you will use such a gadget correctly, and the chances of losing files from it will be significantly reduced.
