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.
SSDs have no moving parts and, depending on their design and usage scenario, can consume less power than comparable HDDs. In mobile devices, this can have a positive effect on battery life. In practice, SSDs are used in many areas including: Business applications, gaming, mobility and servers.
