After our comparison of memory cards, in which we have analyzed the best models, we are going to explain what you should look for before buying one of these cards. In this purchase guide, you will discover the keys to buying the card that best suits your needs and your pocket.
Although most memory cards have adapters that will allow you to use them in almost any device, it is important to know the different types of memory cards that exist. Today, three types of cards can be found on the market, depending on their size: SD, mini SD and micro SD, also called TF or transflash.
SD cards were the first to appear on the market, so they are considered an old-fashioned model, although they are still used. They have dimensions of 32 mm high, 24 mm wide and 21 mm thick. This format is the most common among photographers and camcorders, in part because they are big enough not to lose them, but small enough not to take up too much space.
Mini SD cards were the first slightly smaller evolution of traditional SD cards, but they have long since become obsolete and are no longer used today. Micro SD are the most common format today, since they are used in electronic devices such as smartphones, game consoles and tablets. They are 15mm high, 11mm wide and 10mm thick.
Depending on the type of device in which you are going to use it, you must choose one type or another. Remember that micro SDs usually have adapters, which will allow you to use them in SD slots, but the opposite will not happen, so when in doubt, it will always be better to choose a micro SD.
In turn, micro SD are divided into: micro SD, micro SDHC and micro SDXC. The micro SD are obsolete, since their maximum capacity was 2GB. The micro SDHC have capacities from 2 to 32 GB and Fat32 system that prevents recording files of more than 4GB on them. Finally, the micro SDXC, the most recent, have capacities that can reach 2 TB and an exFAT system that eliminates writing limitations.
Finally, if what you are looking for is a specific card for a photography camera, the best are Compact Flash or CF, with capacities that exceed 2 TB and a transmission speed much higher than traditional memory cards.
We continue this guide to buy the best memory card by explaining this factor, which can be complex. The class of memory cards indicates the minimum writing speed of a card. The class is indicated by an icon on the card itself with a number: 2, 4, 6 or 10. Even if a card has a high class, if its transfer speed is low, it will be slow. The class only expresses the minimum guaranteed speed, but the transfer speed is expressed in MB per second.
It is best to always buy Class 10 cards, which have a minimum speed of 10 MB per second, one of these cards will be good and cheap and will meet most needs. Class 6 offers 6 MB per second and so on up to Class 2.
Recently, Class V memory cards, that is, Video Speed Class, have appeared. These cards meet all the requirements for video recording in all its qualities: 4K, 8K, 3D and 360º virtual reality. The speed of these cards is expressed by “Vson” which can range from V6 to V90, the former being a minimum speed of 6 MB per second and the latter 90 MB per second.
How much capacity should I buy the card? Well, as always, it depends. The memory capacity will affect how much the card costs, so you must be very clear about what you are going to use it for. Nowadays, mobile phones have set the minimum internal memory standard at 64GB, so any card below that will be small.
Today, 64GB cards are the best value for money for home or “off-road” use. However, for professional use, 128 or 256 GB cards are best, as they will allow you to store more information, take more photos or shoot more video without having to change cards. In the same way, those users who are looking for a card for a game console should choose models of 128GB or higher, if they want to have enough space.
