Introduction

ADATA is Taiwan’s largest manufacturer of flash storage and DRAM memory for computers. They have been at the forefront of SSD development for many years, bringing us famous SSDs like the SX8200, SX900, and S510.

XPG is one of ADATA’s sub-brands and creates products optimized for the needs of gamers.

With the Gammix S70, ADATA XPG uses a controller vendor we rarely see. Innogrit has been building SSD chips with a focus on the value segment for a long time. Now, they’ve released the IG5236 “Rainier” controller with support for PCI-Express 4.0. Besides the controller, 3D TLC chips are used. They have been rebranded by ADATA; I suspect these are Intel/Micron B27 TLC. Two 1 GB DDR4-3200 DRAM chips provide 2 GB of storage for the mapping tables of the SSD.

The XPG Gammix S70 is available in capacities of 1 TB ($200) or 2 TB ($400). Endurance for these models is set to 740 TBW and 1480 TBW respectively. ADATA provides a five-year warranty for the S70.
