An SSD (solid-state drive) is an advanced electronic storage medium that stores data on flash memory chips. In contrast to conventional hard disks (HDDs), which store data on rotating magnetic disks and use mechanical read/write heads, an SSD has no moving parts. This makes SSDs faster, quieter and more robust.
SSDs use semiconductor memory to store data non-volatile, which means that the data is retained even without a power supply. The memory chips in SSDs are able to read and write data in fractions of a second, resulting in significantly shorter access times and higher data transfer rates.
The most important advantages of SSDs are their high speed, reliability, storage density, reliability and energy efficiency. They are insensitive to shocks and vibrations, which makes them ideal for mobile devices such as laptops and tablets. They generate less heat and require less energy, which contributes to longer battery life in mobile devices. In practice, SSDs are used in many areas including: Business applications, gaming, mobility and servers.
