About SSD (Wiki’s version): A solid state drive (SSD, also called solid state disk) is a data storage device that uses non-volatile memory (NAND) such as flash, or volatile memory such as SDRAM, to store data, instead of the spinning platters found in conventional hard disk drives. While not technically “disks” in any sense, these devices are so named because they are typically used as replacements for disk drives in situations where conventional drives are impractical.
