High density vertical stackingEtches microscopically fine holes through hundreds of stacked silicon oxide and nitride layers to create dense 3D vertical charge-trap cells.
Empirical Benchmark Verification Matrix
Standardized lab results measuring integer throughput, floating-point vectors, ray tracing, and AI TOPS.
| Benchmark Routine | Measured Score | Uplift vs. Previous Gen | Subsystem |
|---|---|---|---|
| Sequential Read Speed | 2,100 MB/s | Doubles standard UFS 3.1 speeds | Read Throughput |
| Sequential Write Speed | 1,200 MB/s | Instantaneous video buffer flush | Write Throughput |
| Random Read IOPS | 420,000 IOPS | Immediate file lookups | Random Access |
What works
- Doubled Data Throughput Over Previous Generation (2,100 MB/s read speed)
- 2100 MB/s Read
- 1200 MB/s Write
- 128-Layer 6th-Gen V-NAND (3D TLC)
What does not
- Peak sequential and random throughput depends on host chipset memory controller support
- High manufacturing component cost adds bill-of-materials overhead for top capacity tiers
