Power

None of 6 known

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.

Not available

Power while writing (claimed)iMaker's average power during sequential writes. A single average or active figure with no read and write split is stored in both read and write, and the source note says so. A maximum figure, such as Kingston's (MAX) Write, is a peak and is not stored.

Max power consumption (claimed)iMaker's peak or maximum power figure. Not the average while reading or writing. Kingston publishes max read and max write power apart. Store the higher one and name both in the source note.

Average power in light use (claimed)iMaker's average over a mixed client workload such as MobileMark. Not idle power and not read or write power.

Not available

Not available

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.

Sleep power (claimed)iMaker's power in the deepest sleep state, PS4 or L1.2. On a SATA drive this is DevSleep.
