Power while reading (claimed)iMaker's average power during sequential reads, including a figure given at the full read speed. A single average or active figure with no read and write split, such as Corsair's, is stored in both read and write, and the source note says so.

Max power consumption (claimed)iMaker's peak or maximum power figure. Not the average while reading or writing. Kingston publishes max read and max write power apart. Store the higher one and name both in the source note.

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.

Not available

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.

Cooling and build

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.

Without heatsink10Reviewkitguru.net/components/ssd-drives/simon-crisp/samsung-ssd-990-evo-plus-2tb-ssd-reviewRead 14 October 2026The drive has no heatsink as such, only a heat spreader label with a copper layer and a nickel-coated controller. Samsung sells it in one bare version

Tom's Hardware photographs the drive with a basic heatspreader fitted. KitGuru calls the stick-on heatsink in the box optional. XPG sells one pack per capacity, so the heatsink version is stored. The separate MARS 980 PRO has an active cooler and is not this product
