Best SD card readers. A buying guide on the memory card readers in circulation.

SD, MicroSD and other types of cards are a great inexpensive solution for saving your most important data, such as videos or photos. To better manage them it is advisable to get a suitable card reader, but what if you are not familiar with the subject?

If so, finding the best SD card reader could become a stressful experience. That's why I wanted to make a guide to make things easier for you and help you easily find the SD reader that can read and write on the best micro SD cards.

How to choose the best SD card reader

Card readers, in general, are not too complicated devices. Therefore, their most important characteristics are:

Read / write speed

The read / write speed indicates the speed at which the card reader will transfer data between devices and memory cards. Your super-fast SD card will be of little help if your card reader doesn't support its full speed. Therefore, before buying, determine what the characteristics of the reader are and try to get the most out of your investment.


There is nothing more to say about the price, except that you should choose the card reader according to your budget. Keep in mind that price is not always a guarantee of quality and that there are many affordable devices that offer performance worthy of the best SD card readers. For this reason, do not rush your search.


Fast performance and an affordable price will be worth very little if your device isn't compatible with the type of card you have. For this reason, think about what your current and future needs are and choose the card reader that will perfectly fit these requirements.


With the variety of memory cards available, you can find the most versatile input options. For maximum control over data transfer, look for a reader with multiple input ports that can function as a microSD card reader, CF card reader, and standard SD card reader to ensure, whatever your storage method , full coverage.


With advances in modern devices, it is necessary to have a USB SD card reader to connect. If you're still using standard USB devices, a USB-C type won't be of use to you, so make sure you're not buying the wrong thing.

LED Indicators

While not always essential, an LED indicator is useful for measuring when the reader is plugged in, warmed up, ready to use, and finished. A flashing light usually indicates a one minute wait, while a steady light indicates that you are ready to go.
