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. A maximum figure, such as Kingston's (MAX) Read, is a peak and is not stored.

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.

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.

Write cache size (measured)iData written at full speed in one long sequential write on an empty drive before the speed drops.

548GB5Reviewtomshardware.com/pc-components/ssds/kingston-nv3-ssd-review/2Read 14 October 20262TB sample with SMI SM2268XT2 controller and Kioxia 162-layer BiCS6 QLC flash. Iometer sustained sequential write, 1 MiB blocks, QD32, over 15 minutes: almost 5.7 GB/s for just over 96 seconds, which the review calls a 548 GB cache. After the cache the drive drops straight to about 250 MB/s, which the review calls a folding state, so the post-cache write field is left empty

226GB9Reviewtomshardware.com/pc-components/ssds/samsung-990-evo-plus-ssd-review/2Read 14 October 20262TB. Iometer sustained sequential write, 1 MiB blocks, QD32, 15 minutes. The review says the drive wrote at almost 6.1 GB/s for over 37 seconds and calls the total cache 226 GB: 216 GB of dynamic cache plus 10 GB of static cache, more or less exactly what the test found. The sequential write chart drops at about 39 seconds

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.

Review text: TLC write speeds around 1.5 GB/s after the cache is depleted, stored as 1500. The chart shows 1,400 to 1,500 MB/s right after the drop. The steady state average over 15 minutes is 1,777 MB/s and is not stored

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.

48°C5Reviewtomshardware.com/pc-components/ssds/kingston-nv3-ssd-review/2Read 14 October 20262TB sample, no heatsink. Review text: the drive only reached 48 C, taking the higher of its two sensors, about 22 C ambient, Intel Core i9-12900K on Asus ROG Maximus Z790 Hero, drive prefilled to 50 percent and tested as a secondary device

65°C9Reviewtomshardware.com/pc-components/ssds/samsung-990-evo-plus-ssd-review/2Read 14 October 20262TB, bare drive, no heatsink. Maximum recorded temperature of 65 C on the primary composite sensor, about 22 C ambient, Intel Core i9-12900K on Asus ROG Maximus Z790 Hero. The review says the drive should not need a heatsink. KitGuru logged 49 C in short benchmark runs, which is a different method

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".

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.
