Most modern electronic devices have built-in memory, which stores various data – from the operating system that manages a device to the user’s personal data. However, an internal memory is not always used for these purposes, sometimes it is convenient to use an external storage device. Different memory cards became very popular among these external devices. In the context of this trend, let’s talk about how to choose and buy the best memory SD card reader for digital media.
A memory card reader is a device for reading information from various memory cards and transferring it to such cards.
Based on this definition it is easy to understand what actually a card reader is.
Let’s consider the main characteristics of the card readers in detail:
1. Type of card reader.
Card reader types are determined depending on their placement.
There are internal (built-in) and external card readers on this basis.
- A built-in (internal) card reader is placed in the body of the device with which it is used in most cases (very often cases of computers or laptops).
Recently, such readers have almost completely replaced the slots for floppies in modern PC.
You can also install an internal card reader, even if it was not originally.
- An external SD card reader is connected from the outside. Often this connection is made via a standard USB (mini/micro USB) cable.
An external USB memory card reader can be connected to any USB device.
There are also wireless SD card readers. A wireless card reader most often uses Wi-Fi for its work. Most wireless card readers can be connected in the standard wired mode.
In most cases, you will be choosing the option of an external card reader, since the internal ones are most often shipped with the main device.
2. Number of supported card types.
In the article about the choice of digital memory card, we looked at features of SD cards that are now dominated by other types.
However, there are devices that use other cards, such as Memory Stick, etc.
However, the SD itself is different – for example, there is a standard SD, but there is also a micro SD.
Therefore, if you need to buy a card reader, first look at the types of cards used in your devices and then look for the appropriate model.
Many card riders are called “All in one”, which means that such a multi card reader can read almost all available types of digital cards.
3. Data transfer rate (speed).
As mentioned above, a card reader connection is made using a USB cable most common.
Now most computers use USB2 and USB3.0.
Accordingly, if your motherboard supports USB3 and the card reader support this standard too – you theoretically will receive data transfer rates up to 5 Gbps.
However, here it is necessary to consider not only the speed of a card reader, but also the speed of a memory card itself.
The fastest SD memory card for today’s UHS-II standard has an exchange rate of up to 312 MB/sec. (2.5 Mbps).
So if your cards are slower, then the expediency of having USB 3.0 is somewhat doubtful.
Needless to say a couple of words about the compatibility of the card readers with different operating systems: if you have Windows, in most cases the OS will detect a card reader automatically, but other OS may require a special reader driver, which you can find on manufactures site in most cases.
About the question – what is a compact card reader price?
We can answer – from $5.
On average, a normal model costs around $10-15. In any case, no more than $30 should be paid (with the exception of wireless models).
Well, after reading the article, choose the best card reader for your PC or other device.
