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

Not available

Idle power (measured)iReviewer's idle reading. Power-saving settings such as ASPM are in the source note. A value read from a chart image counts when the source note says "read from chart".

Cooling and build

1 of 4 differ

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.

With heatsink6Reviewtomshardware.com/reviews/adata-legend-960-ssd-reviewRead 15 October 2026Text: the drive comes with an installable heatsink or heatspreader that is easy to apply. FPS Review says it is in the box and not fitted. The separate LEGEND 960 MAX has a larger heatsink and is not this product. Stored as with_heatsink as for other drives with a heatsink in the box
