The TBW value assigned to a solid-state device is the total bytes of written data (based on the number of
P/E cycles) that a drive can be guaranteed to complete (% of remaining P/E cycles = % of remaining
TBW). Reaching this limit does not cause the drive to immediately fail; the TBW simply denotes the
maximum number of writes that can be guaranteed. A solid-state device will not fail upon reaching the
specified TBW, but at some point after surpassing the TBW value (and based on manufacturing variance
margins), the drive will reach the end-of-life point, at which time the drive will go into read-only mode.
Because of such behavior by solid-state drives, careful planning must be done to use SSDs in the
application environments to ensure that the TBW of the drive will not be exceeded prior to the required life
expectancy.
