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.

1,000mW2Press releasekingston.com/unitedkingdom/en/company/press/article/67692Read 23 October 2026Kingston's launch release (Japanese text, Kingston UK site) gives power per capacity as idle / average / max read / max write: 250GB 2.1 / 2.3 / 2.2 / 3.9 W, 500GB 2.3 / 2.3 / 2.2 / 4.6 W, 1TB 1.4 / 2.8 / 2.1 / 4.6 W, 2TB 0.9 / 1.0 / 2.2 / 5.4 W. The average, 1.0 W for the 2TB, is stored in mW. The workload is not named. The idle figures are plain idle, not a low-power state, so they are not stored. No power figures for the 4TB

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.

Write speed after the cache (measured)iWrite speed in the first state after the fast cache is full, when the drive writes straight to TLC or QLC. Tom's Hardware calls it TLC mode. The slower folding state and the lowest dip are not stored. Only from a long sequential write test.
