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.

HeatsinkiVersions sold. The base lists every version and each variant row lists its own. A water block or a cooler with a fan counts as a heatsink. A thermal pad or label alone is bare. A heatsink in the box that the buyer fits, as on the XPG MARS 980 BLADE, counts as with heatsink.
