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.

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.

The drive writes at over 12.6 GB/s for over 31 seconds with a cache of about 400 GB. Intel Core i9-12900K, Asus ROG Maximus Z790 Hero, drive prefilled to 50% and tested as a secondary device. The drive then holds about 2.0 GB/s in a mixed state of TLC writes plus copying data out of the cache for about 13 minutes before a steady 2.96 GB/s. The first state after the cache is that mixed state, which the review does not call TLC mode, so measured_post_cache_write_mbs is not stored

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.

Primary composite sensor, about 22 C ambient, active cooling unless noted, same bench. Club386 saw 60 C and KitGuru 36 C with motherboard heatsinks in other methods

KitGuru logged 49 C in short benchmark runs, which is a different method
