Description
An SSD (solid-state drive) is a non-volatile storage device.
SSDs are silent, faster, lightweight, and more resistant to damage than hard disk drives. In SSDs, data is stored in microchips (flash memory), instead of rotating metal disks (HDDs). The data processing rate in an SSD processor is much higher than the data writing rate of an HDD. However, SSDs are also much more expensive per gigabyte of memory than a classic hard drive.
SSDs were originally introduced as data storage and transfer devices. These storage devices are divided into two groups: USB drives (1) and memory cards for electronic gadgets (2).
Components
1 - Top cover
2 - The connection type of the SSD to your system.
3 - The DRAM chip - cache memory. It is a temporary data storage with a small volume, which stabilizes the wear and tear of the memory. This cache memory is not available in all SSDs.
4 - NAND-controller - memory controller. This is the processor responsible for SSD performance.
5 - NAND flash memory; it is responsible for data storage.
