The article will help you familiarize yourself with the basic parameters when choosing a card reader. What are the types, how they differ, the number of supported cards and other cognitive information for the purchase of this device. Choosing a card reader Is a fairly easy task. Everyone can make the right choice, even if you have never heard of such a device. The main thing is only to know the nuances of the operation of such a device, and even then there will definitely not be any problems with the purchase. At TutKnow.ru we will announce the nuances of the card reader, namely, we will name the criteria for choosing such a seemingly complex device.
First, let's decide: do you need a card reader or not?
In principle, an ordinary USB cable can easily serve as an alternative to the card reader. What are its advantages?
- Firstly, in the speed of work, namely, writing and reading information.
- Secondly, the card reader does not require additional software to be installed.
- Thirdly, there is no need to buy USB cables for various devices (after all, such a cable is not universal).
As you can see, the card reader has clear advantages over the USB cable and solves all problems instantly, without unnecessary hassle. But this is achieved only if you have chosen the correct card reader. In other matters, let's figure it out!
And so, let's define the purpose of the card readers
Modern card readers, and not only modern ones, are classified into internal and external.
Internal card readers
mounted directly into the computer system unit. Advantages: such models do not interfere with your work at all with a bunch of wires, you simply cannot see the device.
External card readers
- similar to an ordinary computer USB flash drive (read how to choose a USB flash drive), only slightly larger in size. If necessary, such a card reader can be easily connected or disconnected from a computer or laptop, and then carried in your pocket or purse. There is no obvious advantage of one type of card reader over another. Therefore, you should choose such a device, focusing on your external factors of life.
First, think about the variety of support for different types of cards
In order not to buy a new device every time, because the previous one is not relevant, your card reader should work absolutely with all the home appliances you use.
Consider a card reader. What do you see? First of all, there are many holes for memory cards. So, the more of these "holes", the more memory cards your device will be able to work with. Supported types of memory cards are the first and most important criterion for choosing a card reader. At home, prior to purchasing, determine and write down all the types of memory cards you are using. This will help you choose the right device. If it is difficult to make a choice of a specific model, take a card reader with the inscription "All-in-one". This "reads" all existing types of cards.
Card reader speed
The speed of the card reader shows the time required to read / write information of a certain volume. In principle, the speed of all existing models of such devices is the same. The main thing is to take into account the speed characteristics of both writing and reading when choosing. The ideal option would be when these values coincide as much as possible or are completely equal.
If your motherboard has a USB 3.0 port, then the speed of the card reader will not be a purely nominal characteristic for you. The fact is that normal specifications can operate at a speed of no more than 0.5 Gb / s, while devices connected to a perfect port are free at a speed of 5 Gb / s. The main thing is not to forget to take into account the various characteristics of writing and reading.
Picked up a model? Check if it is compatible with your computer?
Each card reader has its own software that can work with certain operating systems. Expensive device models support absolutely all operating systems, but not all of us will buy an expensive card reader. While in the store, remember the operating system installed on your computer and check if it is in the list of supported cartridges on the package.
This is the end of the tips for choosing a card reader. You just have to go to the store and be sure of the correct purchase. And if anything, then you can get additional advice in a specialized computer store. Happy choice!
