Frequently Asked Questions: MicroSD Cards
What is a micro SD card and where does it come from?
A micro SD card is a physical storage medium in a compact memory card format. It is just 11 x 15 cm and is ideal, for example, for use in mobile devices.
San Disk was the manufacturer of the first SD card that could be found on the market. You have paved the way for the Micro SD card and brought it to the market for the first time. At the beginning, this form of fast storage solution was still called TransFlash. It wasn’t until 2005 that the micro SD card got its real name, which it still bears today.
Micro SD cards are usually predominantly used in mobile devices such as cell phones and smartphones. Micro SD cards are also used in photography and videography. For example, these are used in system cameras. Here they ensure fast and secure storage of the resulting data volumes.
What do the abbreviations of the Micro SD card mean?
Micro SD cards have a wide variety of abbreviations. The overview is quickly lost here. We will help you to keep this, however, and have listed all common abbreviations in the following table:
SD / SDHC / SDXC
The so-called SD Association created these abbreviations to represent the memory size. SD cards often have a storage capacity of up to 2 GB. With SDHC up to 32 GB. And SDXC have a storage space of up to 128 GB.
UHS-I / UHS-II
This combination of letters stands for the transfer speed of the micro SD card. UHS-I cards have a speed of up to 104 MBps. UHS-II have a speed of up to 312 MBps.
What alternatives are there to the micro SD card?
It all depends on the purpose for which you need a new micro SD card. If this is your mobile phone, for example, there are few alternatives. It is usually advisable to use a micro SD card.
If you have a lot of data, you can also consider saving it on an external hard drive. An external hard drive is also a storage medium that is usually in its own housing and can be connected directly to a desktop PC or laptop via an interface connection.
Furthermore, there is now the possibility of online storage in a so-called cloud. Various companies such as Apple or Google already offer these services for a relatively small amount. In this cloud it is possible for you to store all kinds of things.
MicroSD Card: Purchase Criteria
In the following we will show you which aspects you can use to decide between the multitude of possible Micro SD cards. The criteria you can use to make your purchase decision are as follows:
- Storage capacity
- App performance
In the following paragraphs we explain to you what the individual criteria mean and what is important when making a purchase.
Micro SD cards have a wide variety of speed classes. The most common are Speed Class 2, 4, 6 and 10. The speed of the data transfer increases with increasing numbers.
The numbers indicate the minimum transfer rate in MB per second. A Speed Class 2 micro SD card has a minimum transfer rate of 2 MBps.
As already explained before, there are also the SDHC and SDXC cards which can be divided into the two categories UHS-I and UHS-II. The former has a minimum transfer rate of 10 MBps and the latter a transfer rate of at least 30 MBps.
Like so many products that come from the technology universe, speed is very important and should play a major role in the purchase decision. Fast data transfer contributes significantly to a good Micro SD card. So think carefully about how fast your new micro SD card should be.
In addition to the speed, the capacity is the second important factor when it comes to choosing a good and suitable Micro SD card. The principle is similar: the more storage capacity, the higher the price to be paid.
The capacities range from a few GB to over 100 GB. In any case, pay attention to the number which can be seen on the front of the card. It usually stands for the number of gigabytes that the micro SD card has available.
Capacity and speed are the two most important factors when buying a micro SD card!
It is important to keep in mind that a high capacity is not enough to be happy, as it also requires fast data transfer, as already mentioned above.
Another crucial factor when buying a micro SD card is the warranty and protection of the SD card. With the length of the warranty, a seller of Micro SD cards can also generate a certain degree of confidence in their product.
You must always be aware that a defect in your micro SD card can mean the loss of important personal data such as photos or the like.
To prevent such a disaster, some sellers offer a “data rescue service”. The attempt is made to save the data and content that was previously on the now defective card.
For this reason, pay particular attention to the conditions of the guarantee. Also make sure which service is offered to you.
A micro SD card worth US$30 can of course have a much greater value for you personally if there are important personal pictures on it. If you only receive compensation in the event of an accident, in the amount of the purchase price, this could lead to great dissatisfaction.
Another crucial purchase factor is the compatibility of your new micro SD card. Before you buy a new one, you should always check which card type your device is compatible with. There are many devices that do not support all formats and capacities.
Older cameras do not support every shape and card type!
This problem may arise when you want to buy a micro SD card to use to save pictures from your camera. Older cameras in particular do not support every card type.
A decisive criterion when it comes to buying a micro SD card for your mobile phone is the app performance or the compatibility of the SIM card with the various programs on your mobile phone.
There are speed classes A1 and A2 which are at least twice as fast as other speed classes. You can also find this designation on the packaging of the micro SD card.
If you need a micro SD card for other purposes, this is not a decisive criterion, but certainly a relevant one. So it can happen that one day you want to use your micro SD card for something else. For this you need the app performance mentioned.
Facts about MicroSD Cards
What do you do if your micro SD card is defective?
As already mentioned in the last point, there may be documents or content on your micro SD card that are of great importance to you.
If your micro SD card is defective, the most important thing is to keep calm first.
One possibility is to try to have the micro SD card repaired from where you already bought it. This service may still be available in the form of a guarantee. If this is not the case, the costs are usually in the double-digit range.
Of course, that’s not the nicest news, but you probably don’t want to lose your personal data and content either.
Another possibility is to take the rescue of the data into your own hands. In the next step we will explain exactly how this works. In any case, you should be aware of the risk you are taking.
It can certainly work that you save the data yourself and have saved yourself a lot of money. It could just as well be that something goes wrong and the data is lost.
