What are Micro SD memory cards?
Micro SD cards stands for Micro Secure Memory Card. Micro SD cards are digital data storage devices that are available with different storage capacities. The predecessor of the Micro SD card is the normal SD card, which has the largest dimensions. An intermediate size is the Mini SD card, which is slightly larger than the Micro SD card. Micro SD cards have dimensions of 11mm x 15mm x 0.7mm. The cards are based on the memory principle of flash memory and they do not only come in different sizes, because they also differ in storage capacity and speed. The largest storage capacity is SD cards with 1 TB of memory.
What are they used for?
Micro SD cards serve as an external storage medium that makes data portable. While the larger SD cards are often used in computers, micro SD cards are ideal for mobile phones and tablets. Thanks to their compact design, they fit into almost all devices and can be used to store photos, music and much more data. But you can also use micro SD cards in cameras, drones or security cameras that need data storage.
What are the differences?
It's not just the SD card size that varies, because Micro SD cards also have different specifications. Depending on how much data you want to store, you can buy Micro SD cards with different memory sizes. The largest possible memory size is a Micro SD card with 1 or 2 TB. Other sizes of Micro SD cards are:
-Micro SD card 128 GB
-Micro SD card 64 GB
-Micro SD card 32 GB
Other differences in Micro SD cards are the transfer speeds. The speed of the cards is differentiated in speed classes, which have the gradations 2, 4, 6, 8, 10. The numbers stand for the respective Mbit that are transferred per second. The lowest transmission rate is therefore 2 Mbit/s. With high-speed cards, 10 Mbit/s can be transmitted. Ultra High Speed cards have the fastest transfer rates and can transfer up to 30 Mbit/s.
What should I look for when buying a micro SD card?
When buying Micro SD cards, it is important that you have enough memory to store the data you want. If you want to store a lot of photos and videos, your micro SD card must also have enough memory. The transfer speed is also a factor when buying micro SD cards. However, it is important that the respective device supports the memory card. Tip: Buy SD cards with a little more memory to avoid the problem of too little memory for your projects.
