Flash memory is a type of nonvolatile memory that erases data in units called blocks. A block stored on a flash memory chip must be erased before data can be written, or programmed, to the microchip. Flash memory retains data for an extended period of time whether a flash-equipped device is powered on or off.
Flash cache is the temporary storage of data on NAND flash memory chips to enable requests for data to be fulfilled with greater speed. In a common scenario, the system stores a temporary copy of the most active data in the flash cache and a permanent copy of the data on a hard disk drive (HDD). The goal of flash caching is to store previously-requested data as it travels through the network so it can be retrieved quickly when it is needed again. Placing previously requested information in temporary storage, or cache, reduces demand on an enterprise's bandwidth in addition to speeding up access to data.
