ADATA GAMMIX S70 BLADE 4000GB

The ADATA XPG GAMMIX S70 BLADE 4000GB is built around the Innogrit IG5236 Rainier controller (8-channel, NVMe 1.4) paired with a dedicated DDR4 DRAM cache. It typically uses 176-layer 3D TLC NAND (often Micron B47R) though ADATA may vary NAND suppliers by production batch. The design targets maximum sequential throughput over PCIe 4.0 x4. The "Blade" includes a thin, low-profile aluminum heatspreader sized for the PlayStation 5 M.2 slot; the IG5236 runs thermally aggressive, so the thin stock heatspreader can reach saturation under sustained writes and chassis airflow is important. There have also been firmware revision sensitivities reported with the Rainier controller that can cause drive recognition issues, requiring firmware maintenance.
