How to Choose the Right Memory Card

If you go to a modern electronics store, you can stumble upon at least a couple of shelves, completely filled with memory cards. An unprepared man is taken aback by such abundance. What is the difference between all these cards? Why can’t you create a universal memory card? Which models are the most reliable from? This article will tell you all about it.



Each of us would like to imagine a world in which only one type of memory card is sold – only the manufacturer would be different in this case. In the world of interchangeable media it has already happened – remember audiotapes. Although even in those days there were special types of audio cassettes designed for voice recorders or answering machines, they were simply sold in not every store, so their existence was suspected by few. Not to mention the fact that there were options for 45, 60 and 90 minutes of audio recording.

So why can’t manufacturers limit themselves to a single memory card? First, they are hindered by the creators of electronic devices, rushing from one form factor to another. If smartphones and tablets most often use microSD cards (the minimum size of these gadgets are affected), photo equipment manufacturers usually give their creations a slot for the SD card. And the PS Vita game console has received a proprietary type of memory card.

Secondly, not all users will be satisfied with the universal capacity of the memory card. For example, manufacturers can stop at 32-gigabyte volume. That alone will be enough. But other people want to buy a cheaper card – they do not need such capacity, as they are not going to save on a replacement media movies and huge volumes of music. And the third such capacity will be even small, as they are going to use the memory card in the video camera, recording the picture in 4K resolution. That’s why there will never be universal cards, so you will always have a very difficult choice.



There are some of the most popular types of memory card. The medium of a format can be installed only in a specially designed slot for it. That is, the card from PS Vita can not be installed in a camera or smartphone, even if they are also manufactured by the Japanese company Sony. Therefore, the form factor of the memory card should be determined first thing. The most popular types of cards are now:

  • MicroSD is the most common form factor. Such cards are inserted into almost all smartphones that have a memory extension slot. With a special SD adapter, the card can be placed in a camera, laptop or video camera.
  • SD is an equally common memory card format. It is larger in size and has a record lock. Usually such cards have decent speed characteristics and adequate price tag. Used in cameras, printers, video cameras and many other electronic devices.
  • MemoryStick Pro Duo – these cards are supported by some gadgets produced by Sony. For example, the PlayStation Portable game console and certain camera models.
  • PS Vita is a proprietary type of memory card supported only by the game console of the same name. Special software is written on it, so it is impossible to install another card in this console even by using some adapters.
  • CompactFlash – these memory cards are quite large in size and very decent recording speed. Most often used in professional SLR cameras and some video cameras.



Many memory cards are packed with their class. In fact, this indicates the speed characteristics of the product. The higher the class, the higher the recording speed.

  • Class 2 or 4 are very low-speed media. Suitable only for use in button phones or simple MP3 players. It is not recommended to purchase for installation in a tablet or smartphone, as the operating system with such a card will work noticeably slower!
  • Class 10 is probably the most popular memory card class in today’s market. Its speedy features are enough to record video at Full HD resolution. This suggests that such a card can be used in the vast majority of video cameras. And certainly such media are ideal for tablets, smartphones and cameras (except for professional).
  • UHS-I is a more high-speed standard. It was developed specifically for devices that write videos in 4K resolution. Perfect for most SLR cameras, action cameras (including GoPro Hero 4′ Black) and video cameras.
  • UHS-II and above – such high-speed cards are still required only by professional photo and video technology. In particular, photographers use them to load the clipboard of their device less, squeezing more frames during serial shooting. Well, videographers on such memory cards write 4K-video with the maximum bitrate.



The memory card is a miniature thing. And the smaller the electronic device, the easier it is to fail. That’s why some memory cards break down so quickly. That’s why you only buy products from time-tested companies! Forget about ordering Chinese products in the relevant online stores, as fakes rarely last long.

We advise you to pay attention to maps produced by Kingston, Samsung, Silicon Power and Transcend. A good choice will be a card from Sony,but in this case you will make some overpayment for the brand. This does not apply only to cards of a specific format designed for game consoles of this company – other manufacturers are rarely engaged in their release. Well, if you want to get the maximum quality, then look towards the products SanDisk. Tests show that these cards correspond to the stated characteristics and serve for many years. On some models the company provides a 10-year, if not a lifetime guarantee!



  1. Most often, when choosing a memory card, the following error is made: the consumer begins to listen to the seller-consultant. And he offers a stale product that has not the best characteristics. Think with your head!
  2. Also, many buyers want to save money on buying a replacement media. They buy a card of a little-known manufacturer. For example, it is strictly not recommended to purchase products of zumo. Someone has such memory cards work long enough. But most often they refuse if not in the first days of use, then a week or a month after the purchase. And, as luck would have it, by the time the check is thrown out, because of what the warranty exchange can be forgotten.
  3. A less common mistake is buying an unsuitable speeding card. But rarely it is allowed only because in our country not everyone owns a flagship smartphone or 4K video camera.
