Flash memory has been widely used for storage devices in various embedded systems and enterprise computing environment, due to its shock-resistance, low power consumption, non-volatile, and high I/O speed. However, its physical characteristics impose several limitations in the design of flash-based Solid State Disks (SSDs). For example, its write operation costs much more time than read operation, and data in flash memory cannot be overwritten before being erased. In particular, random write operations in flash memory have a very poor performance.
