Price (trend) is a sparkline of every recorded price point, newest on the right — green line = falling, red = rising. Expand a row for the full chart with low / high. Snapshots are appended weekly and on request; most rows start with a single Sept-2026 point, so trends fill in over time.
2026 is a NAND-shortage year. Street prices roughly doubled vs 2025 and SATA has inverted — an 870 EVO now costs more per TB than a 990 PRO. Treat every price as a snapshot; the $/TB column is the honest comparison.
DRAM vs DRAM-less (HMB) — DRAM-less drives are fine as game / bulk storage, weaker as an OS drive under sustained mixed load. QLC is cheaper per TB with lower endurance and slow post-cache writes; the TLC-only / Hide-QLC filters remove it.
Speeds and TBW are the manufacturer rating for the listed capacity. Some budget drives are a component lottery (NAND / controller change under the same part number) — flagged in NAND as varies.
