Shopping guide

When it comes to buying an SD card, there are many aspects that we must evaluate, beyond how much the product costs or its capacity. And it is that the high demand that many current devices have requires more advanced systems to transfer data. So so that you are clear about everything you need to know, we leave you the advice of our guide to buying the best SD card, in which we reveal all these aspects to you.

card capacity

Although there are many aspects that we can deal with when talking about these cards, we are going to start talking about capacity, as it is still key when it comes to finding a good and cheap SD card.

This capacity is very variable, as you will see when you see any comparison of SD cards. Currently, these SD cards offer a capacity from 8 or 16 GB, with really cheap prices. So if you don’t have huge storage needs, you won’t have to overspend on unused space either.

This scale grows according to the computer’s own numbering, so that we will have 32, 64, 128 or 256 GB cards. In these last two models, prices are already beginning to grow, as is the case with the 400 GB or 512 GB models, which are currently the market ceiling.

These latest models, starting at 128 GB, are suitable for high-demand products such as high-end digital cameras and the like. In any case, it will not take long to see cards of up to 2 TB, although surely at more than high prices, as is the case with current flash drives that have that capacity.

card size

Another important issue for the card to work properly is to have a size adapted to what the device needs. The three main sizes are the conventional SD formats, the micro SD and the mini SD.

The conventional SD card is the usual one for photo and video cameras, having specific compartments for its assembly, generally by pressure. The mini SD format is the intermediate, being less and less frequent as it is being replaced by micro SD. This last format, the micro, is the one currently used in mobile phones, tablets and in most devices on the market.

In addition to what has been stated, the mini and micro models are usually accompanied by adapters, so that you can convert these cards into SD-type models by simply inserting them inside. Something that helps manage the content on those devices that only have an SD input.

Card operating class and speed

Another important aspect of an SD card is the class it offers us when it comes to moving data. A class that has been growing at the same time as the needs of different devices. For this reason, today it is difficult to find 2 or 4 cards, with transfer speeds of 2 and 4 MB/s respectively.

Currently, the most advisable thing is to bet on class 10 cards, which, as their name suggests, offer us a transfer speed of 10 MB/s. It is the necessary and recommended standard to record videos in high definition 1080P, although we can also resort to UHS I Class I, which maintains this same speed although with the option of recording video in real time.

But if it is about making the leap to 4K technology, it will be necessary to resort to the UHS I Class III models, which increase the transfer speed up to 30 MB/s. It is what we will need in case we want to record video at the highest possible quality.

By the way, it should be remembered that each class guarantees a minimum speed, but that the actual operating speed of the device is usually higher, and it is also common for the card to offer better performance than those that its class simply establishes. In fact, some cards are around 100 MB/s in speed, as you can see by just looking at the market.

Strength and durability

As a final aspect, it is necessary to take a look at the resistance and durability offered by the SD card we are talking about. And it is that if we plan to use the card in complex conditions, such as those suffered by a sports camera, it will always be convenient for this card to have sufficient resistance so as not to lose our photos or our videos.

Fortunately, there are several manufacturers that have products dedicated to this purpose, offering high-level resistance to all kinds of problems. Among the risks covered are shocks, drastic changes in temperature or even X-rays, so there is no problem when passing the cards through an airport scanner, for example.

In any case, even if you do not plan to give it a particularly intensive or risky use, it is always convenient to have a product with a guarantee and high resistance. And it is that a poor quality card can mean the loss of its content, which can be easily avoided. We will not mention names, but it is easy to know which manufacturers we are referring to just by looking at the trajectory and the opinions that their products arouse among users.

Frequently asked questions

Q1: How to format SD card?

The process of formatting an SD card is as simple as that of any other memory device or similar that we connect to our computer. So once the card is connected, we will only have to access the Windows file explorer, select the drive with the right button and choose the format option. The same procedure can be executed on Mac computers, using the disk manager and following the usual process.

Q2: How to transfer media files to SD card?

If you want to transfer media files to your SD card, simply move or copy them the same way you would a conventional storage drive. So all you have to do is choose the files in Windows Explorer and move them to the drive where the card is located. By the way, if you want to move media files from card to PC or wherever, you just have to do the same process but in reverse.

Q3: Which SD card is better for recording video?

It all depends on the video quality that we want to record, as well as its format. For video recording in Full HD format, it is necessary to have a class 10 card, with which to ensure good data transfer. If we also want to record in real time, it will be necessary to opt for a class I UHS model, which significantly increases performance.

However, this class is not enough to record video in 4K format, and it is recommended to go one step further in this new class to class III UHS cards, specially designed for these uses.

Q4: Which SD card to buy for SLR camera?

Everything will depend on the image taking and video recording capacity offered by the product. In the event that this recording is made in Full HD format, it will be necessary to use class 10 cards, while if we have the possibility of recording in 4K format, it will be necessary to use class III UHS cards.

As for the capacity, it all depends on what we need, although theirs is to bet on models of 64 or 128 GB at least. Especially if you plan to take high-quality photos or record videos in 4K format, in which case it is necessary to have the largest possible storage capacities.

Q5: Where to store SD cards?

The storage of SD cards is not a minor issue, since inadequate storage can deteriorate them and even cause the loss of data inside them. Something that we can avoid by keeping the cards in a cover or case, which avoids these risks and keeps them protected.

Additionally, it is also convenient that storage be carried out away from sources of heat, magnetism and other risks that may damage the cards. In the market it is easy to find covers to organize your cards comfortably, as well as with the corresponding security.

Q6: How to recover damaged SD card?

Virtually all SD card manufacturers offer specific applications with which we can recover a damaged SD card. These applications are responsible for verifying the data structure of the product and try to restore access to data that is still recoverable.

In the best of cases, you will be able to recover part of that data, it is advisable to save it in another storage, to avoid problems. Once the data is recovered, it will be necessary to format the device to recover its integrity and return the card to normal operation.

Q7: How to fix SD card full with no files?

This problem is usually caused by a misallocation of space, which can cause some files to not appear or the card to run out of space when there really is space inside. Thus, to solve the problem, it is convenient to change the device to which we connect the card, such as a PC or a laptop, to verify exactly what is inside it.

If there are no files or space, it will be necessary to recover what we can from the card and format it, preferably from the device in which we are going to use it.

Q8: What SD card does the Nintendo Switch use?

When it comes to expanding the storage of our console, we can use practically any SD card on the market today. It is only necessary that it has a high transfer speed, at least class 10, as well as ample capacity to store games and everything we need inside. In any case, some products have been specially designed for this console, so if you prefer them, it will be easy for you to find them.

Q9: Why doesn’t it read the SD card?

To begin with, it is convenient to verify that the SD card is correctly placed in the reader, pressing it a little. It is also a good idea to clean the connectors of dust and other debris, in case it is possible that the dirt present makes it difficult to read. Finally, if we continue to have reading problems, it will be necessary to try the card in another reader, to verify if the problem is with the reader or with the card itself.

In any case, it is convenient to distinguish between a card that is not detected, which we can solve with this procedure, and one that is detected but cannot read its files, in which case it would be necessary to proceed with its repair.

Q10: How to fix damaged SD card without formatting?

To repair an SD card without formatting it, so that we can access the files inside it, we can use any conventional hard drive diagnostic tool, which will look for errors in the drive, repair them if possible, and offer us device access. If this is not enough, we will have to resort to a specific file recovery unit for these storage devices and cross our fingers to see what we can save.

How to use an SD card

The SD card has become the perfect complement for our photo and video cameras, as well as for our mobile, in case we opt for the micro SD models, which are compatible with these terminals. A model that requires a certain procedure for its use, which we will reveal below to get the most out of it.


When inserting the card into the device, it is important that we place it correctly. The good news is that the cards are shaped to prevent misplacement of the product. Therefore, whether we are talking about an SD or a micro SD, the installation of the card is easy, since it only fits in a specific way and there is no possibility of error. What we do need to verify is that the card is properly inserted in its place, so that the contacts do their job correctly.

initial formatting

Although it is a point where there is some controversy, the truth is that most users recommend formatting the SD or micro SD card. However, this formatting must be executed directly from the device itself, which prepares the internal space to store the data in a better way. The procedure depends on the device we are talking about, so you will have to take a look at the menu options to see how to proceed.

Card Usage

If you’ve done your homework, your card will be fast enough to give you the performance you need when it comes to file transfers. But for this speed to be maintained, it is important that you do not fill the card completely. And it is that as it happens with SSD hard drives, SD cards lose part of their performance when more than 90% of the storage is occupied. So unless it is essential, it is not convenient to rush the space.

moving the content

When it comes to extracting the contents of the card to make copies of the photos on your camera, for example, or the contents of your mobile, the fastest option is usually to connect the card directly to the PC or laptop. However, if it is a micro SD mounted on a mobile, you can also do it via USB port from the device where it is installed, since the transfer speed is usually not bad either. In the case of micro SD cards, do not forget to use the corresponding support to “convert” the micro SD card into a conventional SD.

card care

As a storage device, the SD card requires some care, with which to extend its useful life and avoid failures. Among these cares are keeping the card away from heat sources, as well as direct sunlight, always keeping it in its case when we are not using it, as well as avoiding bumps or unnecessary stress.

On the other hand, it is also a good idea to run an error detection tool from time to time, such as Scandisk. And in case of card failure, there are tools that make it easy to recover the data inside it, or at least try.
