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.

Highest temperature under load (measured)iHighest drive sensor reading in a sustained write test of 10 minutes or more, on the bare drive unless the row is a heatsink version. Short benchmark runs do not count. Heatsink, airflow and room temperature go in the source note.

80°C7Measurementtomshardware.com/reviews/adata-legend-960-ssd-review/2Read 15 October 2026Text: the 2TB idled at 34 C and after 1TB of consistent writes hit up to 80 C but did not quite throttle. Ambient is typically 24 C, the load is sustained writes at full speed, and the page names a sensor and an infrared thermometer without saying which gave 80 C. The review says the included heatspreader keeps the drive from throttling, so the drive was most likely tested with it fitted

The review does not state the duration of the test for this reading. The heatsink ran hotter than the Inland Gaming Performance Plus.

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.
