Power while reading (claimed)iMaker's average power during sequential reads, including a figure given at the full read speed. A single average or active figure with no read and write split, such as Corsair's, is stored in both read and write, and the source note says so. 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.
