Abstract
The present disclosure relates to a data storage system and method that includes at least two solid state devices that can be classified in at least two different efficiency levels, wherein data progression is used to allocate data to the most cost-appropriate device according to the nature of the data.
Claims19
A data storage system comprising a plurality of solid state devices, each solid state device being read optimized or read/write optimized and configured for on-demand conversion between read optimization and read/write optimization, wherein data progression is used to allocate data to the most cost-appropriate device according to how frequently the data is accessed.
A method for efficiently storing data in a data storage system that comprises a plurality of solid state devices, each solid state device being read optimized or read/write optimized and configured for on-demand conversion between read optimization and read/write optimization, comprising using data progression to move data to the most cost-appropriate solid state device according to how frequently the data is accessed.
