Abstract: A solid state drive including non-flash memory for storage of short-lifetime data and/or frequently updated data. The solid state drive is configured, when it receives a write command, to identify short lifetime data, and store it in non-flash memory, e.g., DRAM, instead of flash memory and store longer lifetime data to flash memory. When the non-flash memory is volatile memory (e.g., DRAM) the solid state drive may also include an energy storage device, such as a supercapacitor, to provide temporary power to move data from the volatile memory to flash memory if supply power is interrupted.
