Micro SD card - the hard drive counterpart in Raspberry Pi 3B+ computer board
Storage memory is one of the most important components of a computer next to such components as the main processor with Input / Output interfaces. Like previous models, the Raspberry Pi 3B + does not have a factory hard disk or other storage media. The equivalent of a hard drive known from PCs is the micro SD card in Raspberry Pi. The memory card slot is located on the bottom of the Pi 3B + board directly below the DSI connector for the display module. The micro SD card is a very important element for the Raspberry Pi 4B because it stores user files. Its second important function is support during the installation process and startup of the Raspbian OS operating system. Before inserting a memory card into the Raspberry Pi, please transfer all files required to install and start the operating system to it. It is worth noting that depending on the user's preferences, in addition to Raspbian OS, we can also install other Linux distributions, such as Ubuntu Core or Fedora.
Installing the operating system for Raspberry Pi 3B+
The micro SD memory card in Raspberry Pi 3B + is an element that stores user files and folders, but not only. From the level of the micro SD card in Raspberry Pi 3B +, the process of starting the operating system is carried out each time the power is turned on. To install the dedicated Raspbian OS operating system on a memory card, it's best to use the NOOBS application for this purpose. The files of this application should be sent to the memory card, and then insert the card into the micro SD slot located on the bottom of the Pi 3B + PCB on the opposite side to the DSI socket. After starting the computer, we can choose the operating system we want to install. After the whole process is completed, the NOOBS application files are automatically deleted and the Raspberry Pi 4B is ready for use. The installation and functional files of the Raspbian operating system itself require slightly more than 1 GB of free space. The recommended minimum memory card capacity for Raspberry Pi 3B + is 8 GB.
What should I look for while considering the memory card for my Raspberry Pi 3B+?
If you want to design an extensive application on Raspberry Pi 3B +, which is designed to quickly read and write data and save them to memory in real-time, you will certainly be interested in the offer of our micro SD cards. Most SD cards are not designed to install operating system files on them. They were developed for cyclical storage and reading of data, such as those used in multimedia devices to play music files, photos and videos. On the other hand, in-car video recorders and security systems at the airports, data is stored on the card in such a way that the stored data is constantly overwritten during the entire recording process. Micro SD cards offered by our store can also be used in such applications. They are made of high-quality materials and meet the highest requirements for data writing and reading.
