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.

Fanxiang's Amazon table claims 3200 MB/s read for this size and this reviewer measured about 3650 MB/s, in line with the 1TB and 2TB runs, so that claim looks conservative.11Reviewssd-tester.com/fanxiang_s500_pro_2tb.htmlRead 21 October 20262TB model.

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.

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.
