The exact name is <strong>Flash-EEPROM<\/strong>, as it was developed from <a href=\"https:\/\/de.wikipedia.org\/wiki\/Electrically_Erasable_Programmable_Read-Only_Memory\" data-htmlarea-external=\"1\" target=\"_blank\" rel=\"noopener\">EEPROM (stands for Electrical Erasable and Programmable Read Only Memory)<\/a>. The storage of data is identical to EEPROM, but they are read, written, deleted or reprogrammed block by block in data blocks of 4, 8 or 16 kilobytes.<\/p>\n<p>The flash memory is characterized above all by its fast response times and high data transfer rates, which is why it is also suitable for performance-heavy applications such as video editing or 3D. It is also efficient, shock-resistant, compact and contains no moving parts. In contrast to <a href=\"\/blog\/wissen\/was-ist-ram\" data-htmlarea-external=\"1\">RAM (random access memory)<\/a>, flash retains data even after the power supply is switched off, which is why it is mainly used in SSDs, USB sticks, smartphones, cameras and memory cards.<\/p>\n<h2>Advantages of flash memory<\/h2>\n<ul>\n<li>Data is retained even without a power supply. As a result, this type of storage also consumes less power and generates less heat than HDDs.<\/li>\n<li>Works silently and has no problems with vibrations.<\/li>\n<li>Cost-effective.<\/li>\n<li>High read and write speed.<\/li>\n<\/ul>\n<h2>Disadvantages of flash memory<\/h2>\n<ul>\n<li>Higher wear and therefore a limited number of write and erase operations.<\/li>\n<li>The duration of data storage is also limited, which is why flash is not suitable for archiving data.<\/li>\n<\/ul>\n<p>We have already explained the difference between HDDs and SSDs in a knowledge article.
