A maximum figure, such as Kingston's (MAX) Read, is a peak and is not stored.

Idle power (claimed)iMaker's idle power in the PS3 state with APST on, or the state the maker calls low-power idle. On a SATA drive, Slumber counts as low-power idle. A plain idle figure with no low-power state, often near 1 W, is active idle and is not stored. Samsung's Idle with DIPM on is a SATA link power state, so it counts as low-power idle.

The drive then holds about 2.0 GB/s in a mixed state of TLC writes plus copying data out of the cache for about 13 minutes before a steady 2.96 GB/s.
