Solid state disk - Wikipedia, the free encyclopedia |
 | | Solid state disk (SSD, also called solid state drive) is a data storage device that uses memory chips, such as SDRAMs, to store data, instead of the spinning platters found in conventional hard disk drives. |
 | | The first, SSDs based on fast, volatile memory such as SDRAM, are categorized by extremely fast data access, less than 0.01 milliseconds (over 250 times faster than the fastest hard drives in 2004) and are used primarily to accelerate applications that would otherwise be held back by the latency of disk drives. |
 | | To avoid confusion with the first type, these disks are generally referred to as "flash disks." Occasionally, the term is used to include keydrives, since they are technically solid-state and RAM-based. |
