What the current evidence supports

Human editorial judgment · 2026-08-20

Track; not yet

Why
Every performance number available today is a vendor claim about a part that is still under development, and the layer-count reduction from the internal 400-layer target shows the process is at the edge of what channel-hole etching supports. There is no purchasable product and no third-party measurement before 2027, so nothing can be designed against it yet — but the wafer-bonding transition plus the tungsten-to-molybdenum word-line shift are structural changes worth watching because they define the whole 480/604-layer roadmap behind them.
Next
Re-evaluate when independent benchmarks of the CSP sample units appear, or at eSSD mass production in 1H 2027 — specifically verify the 2.5x perf/watt claim under sustained mixed read/write AI-ingest workloads rather than at the wafer/die datasheet level.
