Abstract
A method for dynamically storing data of translation layer in a solid state disk is provided. A data access instruction is sent by a host. Whether the access data is a hot data or a cold data is determined. Whether a flash translation layer (FTL) dynamically established by the SSD is in the partial mapping method is checked. Access rates of different storage medium are compared. The storage position of the hot data of the FTL is adjusted to the storage medium having a faster access rate and the storage position of the cold data of the FTL is adjusted to the storage medium having a slower access rate to increase the access rate.
