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.

360mW2Reviewstoragereview.com/review/kingston-kc3000-ssd-reviewRead 15 October 2026Avg figure per capacity, 0.34W is 340 mW, 0.33W is 330 mW and 0.36W is 360 mW. The workload is not named

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.

5mW2Reviewstoragereview.com/review/kingston-kc3000-ssd-reviewRead 15 October 2026Kingston labels 5mW as Idle for every capacity. At 5 mW it can only be a low-power state, though the datasheet does not name the state. Some retailer copies print 50mW for the 512GB and 4TB

Not available

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