    wear leveling

    Wear leveling is a process that is designed to extend the life of solid state storage devices. Solid state storage is made up of microchips that store data in blocks.

  • write amplification

    Write amplification is an issue that occurs in solid state storage devices that can decrease the lifespan of the device and impact performance.

  • write amplification factor (WAF)

    Write amplification factor (WAF) is a numerical value that represents the amount of data a solid state storage controller has to write in relation to the amount of data that the host’s flash controller has to write.

  • write cycle

    A write cycle is the process of recording data on a NAND flash solid state storage device. Write cycles are also called program/erase (P/E) cycles.

  • write endurance

    Write endurance is the number of program/erase (P/E cycles) that can be applied to a block of flash memory before the storage media becomes unreliable.
