Memory card for Raspberry Pi 4B

Most of today's multimedia devices have built-in memory, most often in the form of a hard disk, SSD, memory card. The device memory is a data carrier that enables the process of saving and reading a file, e.g. in cameras, portable MP3 players, cell phones and computers. What is worth emphasizing, if we need more space for our files and folders, then the built-in memory can be expanded easily and quickly. For this purpose, the most frequently chosen solution is to connect a micro SD memory card. The Raspberry Pi 4B minicomputer, like its previous generations, is standard equipped with a slot for such cards. The micro SD memory cards for Raspberry Pi 4B offered by the Botland store are available in several different capacities and data read/write speeds. Choosing the right memory card for your minicomputer is a guarantee of proper operation in any application. We offer high-quality micro SD cards for Raspberry Pi, which ensure reliable operation and a quick process of data saving and reading.

Micro SD card as mass storage in Raspberry Pi 4B single-board computer

One of the most important components of a computer next to the main processor and Input / Output interfaces is its mass storage. It is a non-volatile memory, which means that after turning off the power supply, the data stored in this memory is stored all the time, in contrast to the RAM memory, which is volatile memory. Like the previous models, also the Raspberry Pi 4B does not have a factory-built hard disk or other mass storage medium. The equivalent of a hard drive known from PCs is a micro SD card in Raspberry Pi. Slot for memory card was placed on the bottom of the Pi 4B PCB just below the DSI connector for the display. The micro SD card is a very important element for the Raspberry Pi 4B because it performs the function of storing user files. The micro SD card in Raspberry Pi 4B is also needed to install and run the Raspbian OS operating system. Before inserting a memory card into the Raspberry Pi, you must upload to the card all the files necessary to install and run the operating system. It is worth adding that depending on the user's preferences, in addition to Raspbian OS, we can also install other popular Linux distributions, such as Ubuntu Core.

NOOBS - the easiest way to install the operating system for Raspberry Pi 4B

The micro SD memory card in Raspberry Pi 4B is an element that stores user files and folders, but not only. It is from the level of the micro SD card in the Raspberry Pi 4B that the process of starting the operating system is carried out, each time the power is turned on. The minimum recommended memory card capacity for Raspberry Pi 4B is 8GB. The installation and function files of the Raspbian OS themselves take just over 1GB of space. The easiest and fastest way to install the Raspbian OS operating system on a memory card is to use the NOOBS (New Out Of Box Software) application. After downloading, the NOOBS installer files should be uploaded to the memory card and inserted into the slot on the bottom of the PCB Pi 4B. After starting the computer, we can choose which operating system we want to install. When the whole procedure is finished, the NOOBS application files are automatically deleted and Raspberry Pi 4B is ready for use.

Which micro SD card should I choose for the Raspberry Pi 4B?

If you already have a micro SD card, you can use it as much as possible in your Raspberry Pi. There are no contraindications for this if you need a micro SD card for ordinary data storage. On the other hand, if you create advanced applications that require fast data reading and writing and a large amount of disk space, then it is worth choosing a card from our offer. Most SD cards are not designed to install operating system files on them. They have been designed to cyclically save and read data as in multimedia devices for playing music, photo and movie files. On the other hand, in case of car video recorders and monitoring systems on the building objects, the procedure of saving data on the card is carried out in such a way that the saved data is overwritten on an ongoing basis throughout the whole operation of the device. For this reason, such a card must be characterized by high quality and long life of the semiconductor structure, because micro SD cards and other types of FLASH memory are designed for a specific number of read/write cycles. After exceeding this number, we will not be able to see the content stored on the card, which means the card is dead. The micro SD cards offered by our store are characterized by high quality and meet your requirements.
