nonvolatile
Won't evaporate easily
Nonvolatile describes something that doesn't evaporate readily at normal temperatures—the opposite of volatile.
In computing, nonvolatile memory retains data when power is turned off: The settings are stored in nonvolatile memory.
Flash drives and solid-state drives are nonvolatile; RAM is not.
Also spelled non-volatile.
