SSD (Solid State Drive)

  • mail
SSD (Solid State Drive) The next-generation large-capacity storage that uses a memory semiconductor as the storing medium. It is called an SSD as it replaces the HDD (Hard Disk Drive) as the auxiliary memory to store the computer’s operating system (OS) and data, and saves data on the semiconductor chip. An SSD does not need mechanical installations like a motor. Instead, it saves data on the NAND flash memory, allowing for faster speeds and higher stability. It also has minimal heating, noise, and electricity use. It can also be smaller and lighter. An SSD is largely composed of the NAND flash that is the data-saving memory, the interface, the controller that oversees the data transfers between memories, external features, and the DRAM that acts as the cache memory. A key feature of NAND flash memory is that it is non-volatile memory, meaning data is preserved permanently even if the power were to be turned off. With the releases of high-performance low-end SSDs recently, they are used on laptops and desktop PCs. They are also used as central data storage for data centers created to save and manage the dramatic increase of data in the big data era.
